CURTIN. the CAli FOE TBOOPS; HißiuyuußO, July 4.—Tne following proclamation wm issued by the Governor to-day: Pennsylvania, ss; - In the name and by the authority of the Common* wealth of Pennsylvania* Andrew J, Curtin, Governor of the said Commonwealth, A PBOOIiiMATIOK. „ More men are required for th« suppression of there, hellion. Our regiments in tho field are to be recruited to tbeir original strength, and iu addition new regiments are to be formed. . Pennsylvania has hitherto done her duty to the coun try. Her freemen are again called on to volunteer in her defence, that the blood of her sous, who have already fallen, may not have been shed in vain, and that we may hand down to our posterity the blessings of Union, and civil and political llberty, which'we derived from our fatheta. The number of men now required, and the regulations for enlistments, will be made known forthwith in geueral orders. Meanwhile, the taien of Pennsylvania will bold tbt-mselvfs iu readluesufor a pioaiptcomoiance with the necessary demand upon their gallant and patriotic spirit. Our noble Commonwealth has never yet faltered, and must stand- 11 nt now, when hor honor and everything that is dear to her are at stake. Gi«eu tinder my hand Hud the great 'aoal of the Stito, at Bnrtbhurg, this fourth day of Jul;. in the year of our loid one thonuJi d eight hundred and sixty-two, and of the Commonwealth the eighty ierentb, Ily the Governor. Eli Sufbhj Secretary of the Common wealth. The pause of the last few days enables ns to more etearly.naderstand the condition of affairs bt fore Richmond. TYe are gratified to Snow that the details which have been spread before our readers verify the conclusions at which we at first arrived. We have fought a great battle, we have gained a great victory, and we think that this week’s conflict, on the banks of the Cbiekahominy, will do more towards' putting down the rebellion than any achievementthe war. The theory Which'seems to be perfectly well established is this: The rebel leaders taking advan- tage of the weak condition of General Mc- Clillan’s army, recall Jackson from the Shenandoah, and combining his army to that of Johnston, made a sudden and gene ral attack upon General McCnsolan. The re inforced foe was powerful and desperate, and there can be no doubt that he calculated upon an essy-victory. Since war first blighted the earth, no gena ral was ever in a more critical and embarrass- ing position than Gem-ral McClbllan. It was a crisis which requited the rarest quali ties of the soldier. He was in a position which ho con’d not control.! Ilia army was weak from ihe hamissing warfare through which it pissed,—it was distant its sources of supply; it was in ari etemy’s country, and on the borders of a swamp whose continual miasma burdened the air withdeaih and disease. An impetuous and desperate commander would have rushed upon the enemy and met destruction. A timid and cautious general- would, have hesitated and trembled until he was overwhelmed. It was not only the foe before him that menaced Gtneial McClellan. Behind him-was au anxious, an eager, and a j along public -sen- tiaent.’ If he;had'been .merely ambitious of military distinction, ho might have made the peninsula an Aceldama, a Golgotha of dead men’s skulls, and, in doing so, would have gone into history with a glorious and venerated name. The occasion demanded the exercise of that moral courage which is so seldom seen in stations so exalted. To retreat at any time is a humiliating task; to retreat at the head of' an army which • only yesterday command! d the admiration of .the world, was to invito criticism and censure of those who had before commended it. General McClellan, in the presence of immediate danger and inevitable disas ter, turned bis army around, -and exe cuted one of the most extraordinary and most brilliant movements -which history records. IVe do not know, indeed, wh-thor to commend more strongly the genius of the general or the bravery of the divisions who met the attack at Mechanicsville. Their courage was superhuman, and it is a thrilling thought that chief among them were our gal lant Pennsylvania soldiers. Hour after hour, through the long day and the weary night, they met the onset of the rebel army. They saved our army from being overwhelmed and beaten in detail on its march to James river. Many of them were slain ; that- splendid di vision of General McCall, -which':we have so oiteo looked upen with pride and exultation, was terribly shattered. -But it did its work nobly, and, in'sustiiaing the charge-of the rebel legions, it saved the army of the To tsniac. ■ This is not saying too much. Wo are not ] disposed to he ungenerous or ungrateful—to 1 deal in exaggeration or'byperbole. Wo sira- • ply repeat the history which the whole world is reading. A lesson of that day id one not to he forgotten. We must study it here at home. In our pleasant walks of peace, with no token' of war visible h-.yond the occasional recruit ing station, or the wounded soldier who claims our sympathy, wo must bring home to ourselves the example of our brothers on the banks of the Chiekahominy. We must not recriminate nor condemn. We must be patient, forbearing, and se:f-sacrificing. Tho danger is too itaminont and' tho dufy is too great for tis to pause, and hesitate, and ques tion. It would be unprofitable for us to ask now, why it was that Gen. McClellan was left with an insufficient army before Richmond. It would be disgraceful for us to become a party to the anger and animosity which- this question has engendered. The presout is too exacting for us to quarrel over the past. All weknawis this, Gen. McClellan requires more men. For every man that is fallen two jnen must be sent to take his place. In attempt- - ing to destroy McClellan the rebel Confede racy has exhausted tho last sources of its strength. It is weak, emaciated, and gasping, and lingers on to its speedy dissolution. In all these things wo see signs of comfort and courage. When these bloody times are over, and we have perused tue history that- is every day being written, no chapter will be read with more pride than that whieh records the deeds of these midsummer days. It will tell how a great general had the genius to »p]an an exttaordinary military movement, and the moral courage to execute it at the risk of his fame. It will tell how a small army of American soldiers stood like a bar rier before an overwhelming force, and deHed it by a courage equal .to that ot Sparta in her palmiest days. And may we not hope that the chapter will also tell how a great people cxbibitid magnauimiiy and pa tience, and, by a self-sacrificing and uncom plaining loyalty, so.strengthened the hands of the President that the retreat of his great general was hut the recoiling blow which an nihilated the rebellion. .

From all quarters of the army, right, left, and centre, the glad tidings of glorious victories, suc cessful advances, and brilliant skirmishes orowd into the camps, filling the troops with joy and doubling their already high spirits., It seems that, after a long series of delays, Providence has at last enabled us to overcome some of the obstacles put in our way to the suppression of the rebellion and to accomplish a great part of the capture of Rich mond. ■ GENBKALSKBABNBY AND HpOKBE’S ADVANCE. On Wednesday afternoon Generals Kearney and Hooker made a moat brilliant and successful ad vance upon t.be enemy’s lines. In the general ar rangement of tho army these two generals have their troops to the left and left contra. Previously to Wednesday their picket front bore-back when considered in- relation to the rest of the line, and in order to correct this inequality Gen: Kearney s was ordered to advance three quarters of a mile and Gen. Hooker a half mile. A series of en trenchments protected their previous position, and artillery were placed in them to command the ad vanced post and protect its occupation against any force the enemy bring in opposition.' All prepara tions being made, the advance was commenced un der cover of a fire of artillery: to clear the sur rounding country of prowling rebels. The men marched steadily on, a constant shelling and occa sional use of musketry compelling the rebols as steadily to retreat. By six o’clock tho advanced post was oooupied, and another hour secured it in such a manner that all the rebel army could not dislodge the brave troops of these two admirable divisions. The enemy boing on a full retreat, a ■ strong reconnoitring party, was sent further for ward and marched for fully a mile, penetrating the enemy’s entrenchments, and meeting but little se rious opposition, It completely sooured the conn-, .try and eame back after nightfall, bringing several 'prisoners and much.valuable information. A .few of our troops were, killed and wounded in the movement. I did not learn their numbers. • This advance brings our pickets on : the line of the York River Railroad, and to the loft of it : within three and a half to four miles of the rebel ’bapital. Another advance of but half the distance -would givo tho left wing of the army a chance to shell the Rocketts and lower part of the town, and to command the James river, cutting off water communication with Fort Darling. Tha present advance enables us to commence the second pa rallel of the siege works, a half mile in front of the first, and by this time the greater-part of it, to the left cf the railroad, baa Keen thrown up. The gal lantry of the generals and the bravery of their men "deserves the highest praise. ' THE SIXTY-THmn NEW YOBK BBGIIIENT ATTACKED. :: After night, the enemy made an attack upon our pickets, and the 63d New York, a regiment of gal lant Irishmen, were ordered to the front, to protect tho retreating pioketers. The regiment advanced, and,, selecting a favorable spot, lay down upon the ground. Our pickets rallied behind it, and the enemy, continuing to advanee, came within twenty yards of the New Yorkers, when that regiment rose np and fired a deadly volley into them; just as they fired a scattering one at the pickoters.- The leaden hail was so .strongly, kept' up that in' a few minutes the rebels broke and fled, leaving the 63d winner of tha field. One man Was killed and .eighteen wounded out of the regiment. SUCCESSFUL ADVANCE ON THE BIGHT WING. On Thursday it was decided to build a redouln ion a bill, in a large wheat field, in front of the right wirg.. The field aid pea up Rome two hundred yards from a wood on our side, then descends in a hallow, then ascends again to the two rebel earthwfwt®-i:~ menticuml in my last letter asbolus'successfully shelled by the aid of the signal officers. Oar farthest advanced pickets were right on the crest of the hill, and the rebel advanced posts were in the bottom. Twe or three houses and a wood on our right and a wood on our left were also picketed in force by the enemy, and cannon on the earthworks commanded the wholo place. The work was to be done with -great secrecy, and two detachments of three hun dred each, one from the 96th Pennsylvania, the 'other from the 7th Maine, were selected as the par ties to do it. A thrBe*sided redoubt of four hun dred yards length was staked out on the crest of the hill, some ten yards behind ‘our picket, ndvßnoe, and its right rested on tho ruins of an old brick -house, and the left ran back towards the woods on the federal aide of the hill. The 7fch Maine broke ground at ten o’clock on Thursday, evening, working with the greatest assiduity until midnight- of the 96th then set to work, and labored until the redoubt was completed, af half past three, afterwards garrisoning it until a few moments past four. Lieut. Col. Frick, of tho latter regiment, was the field officer under whose direction the work was performed. Two thousand troops behind the hill, and numerous cannon in the woods, were ready at a moment’s notice to resist the enemy, should they attempt any interference with the working parties. Thus, for five hours and a half, in tho very face of the enemy, and within a hundred yards of bis pickets, these six hundred men handled their picks and’shovels, and spades, as they were wont to do in potato digging at home. They labored silently and swiftly, soon throwing up on embankment sufficient for their protection, and afterwards strengthening it, until the streaks of dawn bade them to be on tho alert. Then every man seized his musket and took his position in the trench, ready to resist the anticipated charge from tho enemy, which they seemed only waiting to bo* gin when daylight should enable them to discern the exact condition of affairs. Every soldier was in the trench, musket in hand, and sat there as approaching morning dis pelled tho gloom whieh hung over all nature. OF all were anxious to witness the effect our | bold manoeuvre would have, and "many an eye i piercotl to where sad experience had often taught l that the rebels might he found. Numerous sur | mises were made as to their having discovered oar | operations. Some believed they had evacuated | the place, and advancing day, bringing no attack, | seemed to confirm it- ‘ Some looked askance at a I low range of bushes, and thought. they detected j myriads of rebels lurking in their shelter. Every • one had his opinion of the denouement of which I the early future was’ supposed to be portentous, a ! furious attack by horse, foofci and dragoon. Ad j vancing day, however, soon settled the great ques tion, and sunrise sawthe. rebels gazing with con sternation. upon the long low embankment which i his earliest rays discovered. They had not dreamed | before of gueh Yanb.ee enterprise. During all the j night they were ignorant of wbat was in progress. I Our troops labored so silently that they could not be heard at thirty yards distance, and the long wheat straw growing around effectually shielded them from the enemy’s sight.- Squads of rebels came to their front to gaze in astonishment at this •second Bunker Hill bristling with Yankee bayonets. One man mounted himself on a post to see to more satisfaction, hut a slow and sorrowful dismounting I told the effect it had on. him. Hundreds of them came to look at it, but not an offer was made to molest us. At five o’clock sie Ninety-sixth were relieved, the regiments in reserve during the night furnishing the garrison of the redoubt. Generals Brooks and Taylor were on the ground at day-light, inspecting the work. This brilliant achievement advances our entrench ments on the right wing nearly half ami Lo. In three days we will compel tho rebels to abandon their two earthworks in front of the redoubt. A cannonade, too hot for any troops to withstand, will be poured into them. In tho meanwhile wo sooure possession oflbreeor four hundred yards in advance of the entrenchment, compelling the cnomy’s pickets to fall back, and drive them from two flanking pieces of wood in which their movements have been ex ceedingly annoying.: This is a fair advance up the Richmond'bank of the Chiekahominy, wedging tho enemy away from the river, depriving fchcmof ttioir r»Dge of high hills bordering it, and compressing their entire force closer upon the city. The steady perseverance of the two detachments who did so much wo?k in so short a time, is as oemmondable as the bravery which they showed in. passing five hours and a half in a spot where discovery would have been annihilation. - BATTLE AT MECHANICSYILLB. yesterday afternoon, as was anticipated and hoped, tbe rebels, twenty thousand.strong, crossed the river on the bridges in the vicinity of Me chanicsville. General McCall lay a mile hack of the town and to the loft of it, and General Porter in the vicinity of Dr. Gaines’ house, throe miles to tho left. General Martindale, with his brigade of General Porter’s corps, was with McCall; and Generals Cooke and, Emory, with large forces of cavalry, were a short distance on the right. Thus there were plenty of troops, both in advance and reserve, to cope with the enemy. There is no end to tho number of cannon which Generals McCall and Porter have with them, their corps being con sidered as among tho most efficient in artillery ot any in the army.-. General McCall had. dug rifle pits at tho oelebratod cross-roads near Col. Rich f ardson’s house, and a mile and a half back of Mo-. I chaniesville, and six companies of the Buoktails, I tho sth‘Rosorvo Regiment, opmmanded by Colonel [ Simmons, garrisoned them. The 9th Reserve, Col. Jackson, were just behind them in an oat field, and Btrong batteries supported both. The nature of the ground over which yesterday’s battle was fought is very easily understood: a toad running from Meohaniosville to White House, about a mile from the river, aoross Beaver Dam Creek, behind which General MoCaU was, posted. Thisoreek runs in a crooked course some distance, and enters the CbiekaWominy a haif mUe below the town, at a point just to the right of an, important picket post, known as Sydnor’s houso, and has boon for weeks the chosen line of battle on which our men should stand if attacked, and to which rein forcements were to be sent. General McClellan, however, ordered differently for yesterday. Our men were to retreat and draw the rebels-over.: A hsif mile back of the bridge crossing this stream, this road intersects the 'road from Hanover Court House, a renowned fork, whoso sign-board marking “seven miles to Richmond,” has. for months en grossed' attention. Thiok woods, interspersed with fields, are .on the Meehaniosville side of the Hano- ver road, the other being bounded by vast grain fields. I was away aoross the Chiokahomtny when the first cannon shot was heard from the Meohanios ville battle, and what I write you about it I only glean from flying reports. I first heard the battle about four o'clock in the afternoon, and there was a furious artillery fight until eleven at night, during which, from the. change of .the direction of sound and its increasing distance, we- appeared to have driven.the enemy along way. Rumor 3 from across the river are briefly this: General McCall, upon his approach, gradually retreated from Bea ver Dam creek to the cross-roads, making the ap pearance of being driven back. At that point, he suddenly rallied his men, checked the eneihy, and bad a short, though furious, musketry fight,. The Bucktails jumped out of their rifle-pits on the ap proach of the rebels and gave them the warmest possible reception. One company, in its eagerness, ventured too far, and is said to have been captured. Our troops rallied upon-them, fully checking their advance, when the artillery battle commenced. After this, musketry was but little used, and tho enemy were mowed with most fearful slaughter. Darkness 'at last ended the conflict, and, by midnight, all was silent. At two o'clock this morning General Martindale’s brigade re- treated down the Hanover road to General Porter, at Dr. Gaines’.'house, and this morning; I hear that the Reserves have ” orders to retreat. Hone of these retreats, it must be borne in mind, were made necessary by any movements of tho enemy. They wore all made in accordance with direct-orders from General McClellan, and are part of some strategic idea of his. The fraction of the army aeross the Chickahominy has always been re garded as an independent army of observation more than a part of Richmond’s besiegers. Different oorps hare relieved one another in performing its duties," and these retreats may to more beneficial to us than the furthest advance in that direction. But I can scarcely reconcile the rumors with tho evidence of my own senses. - They speak of con stant stands and retreats all in a ,direction towards me. . On the contrary, the artillery reports I heard plainly receded, and seemed atleast Jhreo miles more distant at the end of the fight than they were at the beginning. Then, at about 9 o’olook last evening,- a report of a groat Union victory , in that direction was officially given out, and the greatest imaginable rejoicing, cheers, band-playing, and joy generally was kept up until midnight. The story was that Stonewall Jackson had come down to tho cross-roads,’ with Fremont and Sigol behind him, and that MoCall attacked him on one flank and Porter on the other, completely cutting his army into pieces. This was read at the head of every regiment, and so. coincided with the cannon-shots heard that it was implicitly believed, the most up roarious joy being the result. .- Whilst it prevailed the sound of..the,.artillery; fight, in the number of reports, far exceeded that at Pair Oaks. Scarcely any mnskotry was per ceptible, and that leads mo to think there wus but little, as in my position I ought to hsvo distinctly heard it if there were. At nine this morning our troops aoross the river are at Dr. Gaines’ house, and slightly in advance of it, tho cavalry bain? back on tho road to White House, guarding in that direction.’ A strong force of all arms of the service is at Grapevine bridge, a mile from Dr. Gaines’, ready to reinforce, if it should to needed. Several cannon shots have been heard in that di rection this morning, and, if necessary,.l shall cross the river with the reinforcements. It is yot too early to send yon any detailed intelligence. J. C. BIKTOTtACEOP WIU.IAM IIF.KKT H.IBRTSOX, . Jambs Arras, 40 Mils* below JSiohuoxd, . • • : Jr.ly 4, 1862. General McClellan has at length accomplished the great scheme which engrossed all his attention for the past two weeks—the transfer of bis army, by a flank movement, from the north and oast of Richmond to the south and southeast of it, and the change - or ms-ease -or'operaQons ana sum-oo m sfipply from the Pamunky to the James river, necessity compelled tho change, and never in military history did an army more successfully and effectually accomplish amanoeuvre of so great mag nitude. Troops had to march with all thoir bag gage; supplies bad to he carried along to meet tho hourly wants of the journey; tho enemy had to bo a hundred times defeated as he pressed too vio lently upon the Federal rear and flanks; sick and wounded were to be cared for, and when a safe arrival upon the James'river was secured, sup plies had to bo provided there with a profusion once in-vogue at White Souse. It was all done and well done. The movement was made; the enemy beaten baok; the supplies scoured; tho sick and wounded sent to hospitals, and all com pleted in the short space of four days. The past ten days have, been among the meat eventful in American history. Doubtless the first reports sent homo to you by frightened sutlers and seared boatmen, fleeing from Whito TCouse.liad the army completely annihilated. Their story would, be that McClellan was entirely surrounded by a vast force of the enemy, who were swiftly and surely cutting his once proud army into pieces, and from tho enemy’s movements.in their vioinity, tho tale thoy would tell would have every appearance of plausibility. To’this moment, I s-.aroely boliovo the version given by your first informants has been diseipated by the truth, as all connection between the army and the North, either by mail or passage, has been for days prohibited. A history of the ten days’ work, however, so nearly correct as I can -give it amid the turmoil around mo, may tend to fill the void and set you aright. THE IIEBELS CIIO3S THE CHtCKAIIOMINr AT KECIIA . - NICSVILIrE. ' No point in all the former front of the army was more eagerly watched or strongly guarded than McohanicsviUe. On numerous occasions I have told you of its importance. The enemy were equally wilh us aware of the great Federal advan tage the possession of Meohanicsville gave, and General McClellan had long ago resolved to make use of their anxiety for its repossossion in order to secure the safety of the -movement across to tho James river. Certain indications of an attempt at crossing were, thereto-e, hailed with delight, and every means resorted to to blind the,rebels as to our real wishes, but at the same time to get them over. Union and Secession coquetted long at that pass, hut Union at length triumphed, and on Thurs day afternoon, June 26, at two o’clock, the enemy threw their bridges across the stream, and the first ranks cautiously passed it. The news of tills,was, of course, instantly telegraphed to General Mc- Clellan, and ten minutes afterwards the extreme left of the army was on the march t® White Oak swamp and the James river. The great movement had commenced. ' Finding the ground not near so hotly contested as they had expected, the rebels threw vast num bers across the stream, in order the more quickly to bear down bur opposition, A brigade of Gene ral McCaH’s Pennsylvania Reserves met them and bravely fought for hours'against.a 'body of troops ten times their number. They fell back, however, as no bravery could withstand the torrent, until they came upon the balance of tho Reserve divi sion, two brigades, and a brigade sf General Por ter’s corps, commanded by . General; Martindale. This was most welcome aid to the jaded troops who sought it. Rifle pits apd seme slight entrenchments also proved an additional means of defence, and Ceionel Simmons’ regiment, the sth, with Colonel Jackson’s 9tb, were the first to rush upon the foe. Here'the rebel advance, which had been made for two miles, was cheeked, and brilliant charges soon broke their columns. ' A- few moments more and the gallant Reserves were driving Secession pell mell into the Chiek&heioiny. At dusk they rested on their arms the victors of the field, a few artil lery shots being the only sound of war, and in the 'silence of evening proceeded to the -sorrowful'-task of burying the dead. JUvery. regiment of the corps was terribly: decimated. Colonel Simmons lay dead upon the field, where he and his regiment - had so immortalised themselves. Dead and wounded, Federal and rebel, ißy all about, and ' with saddened hearts the - brave Pennsylvanians I proceeded to the task before them, placing each loved companion, who had that day sealed his pa triotism with bis blood, in the rude hut honored grave of the soldier.- Rebel wateh- fires surrounded them, and the distant tramp of rebel reinforcements could constantly bo heard. So man passed that night in other mien than sprrov. However, attwo o’clock on Friday morning, June 27, these brave troops, who were effectually chock ing the rebel advance at the “ Seven Miles to Rich mond” cross-roads, received orders to retreat: With groat reluctance thoy- started down the road ; to Gaines’ Mills, four miles distant, knowing, as they did so, that they were leaving a position in which they could hold at bay a hundred thousand men. Slowly they came, making very short.marches and Very long baits, their way lighted by a vast pile Of burning knapsacks, left behind by General The enemy soon discovered the retreat and poured along after, ; thousands to the roar, filling up tho spaoewhieh the ad vaneing front left vacant. - Thoy deployed into the fields, skirmished oo all sides, and spread out as fnr as the rivor would allow them on tbo one band or our harassing oaralryon the other. The Federal plan seemed to be to give the rebels aa much annoyance as possible; firiDg cannon at them, but still, always by retreating, to entice them as far ss possible from their oroBsing plaoes at Meohanios villo. ... , ' ■: It beirg wcll understood that this was to be. our course of operations, , by nine: Qtt the morning of i THE PBESS.-PHILADELPHIA, MONDAY. JULY 7. 1862. Friday the rebels had come down to-and were in full poEßetsion of Dr. Gaines’ house and all the neighboring highlands. Here the Grapevine bridge crosses the Chickahominy river, debouching in the midst of General Smith’s foroes on the federal aide of the stream, and if the enemy were to change their minds and come across it, or, by sending a detachment aoross, were to attack General Smith and moke a junction with their own forces just above him on that Bide of the river, it would jeo pardise the whole army. So General Slocum’s division was ordered out at an oarly hour to guard this bridge. They marched to ! the flat at .the ex-; treme end, and Gen. Bewton’s brigade crossed, the others bivouacking. When General Now ton had passed through the trees bordering the river, he saw the enemy enemy in full force on the hilts above, and immediately returned to report his ob servation, The division lay there until noon, when it was ordered to return towards camp, but one brigade was subsequently wheeled about whilst on the homeward road, and again halted on the flat. At noon cannonading commenced, from one side of the river to the other. General Smith’s batteries had several huge columbiads mounted, which played with splendid accuracy upon the rebels surrounding the Doctor's house. Every Federal gun which could be brought to bear was fired at them, and. their artillery, of which they seemed to have but. few throwing shell, endeavored, but without effect, to silence these terrible batteries. General Porter, too, whose troops were now the opposing force, on their own side of the river, upon their approach sent ehell after shell into them, ail with the most telling results. At two o’clock, on Friday after noon,- the rebel Sine' of .battle, commoneed-at the river’s edge, just at Dr. Gaines’ house, ran up the hill to it, then across,and curving aroupid the Federal troepsreemed to bear away off back into the country Thousands of their men were deployed on the hill sides, a Federal battery, taken across a .corduroy road, above Grapevine bridge, firing into them with deadly effect. Skirmishers and pioketers fought in the flat, and so it was allup the hill and back to the woods. Musketry rattled unceasingly, and the enemy seemed to be met strongly at - all quarters. Porter’s and McCall’s troops lay on.the hills bor dering the Chickahominy, at Woodbury bridge, a mile or two belew Grapevine, their horses grazing under the trees, and the men in lino of battle. This, fight was almost purely au artillery one, ex cepting among the skirmishers, whose rifies main tained a constant cracking. • Infantry, excepting as reserves or; supporting parties, were but little used. There was some severe infantry lighting, however, hut it waß only a prelude to the great battle which gave that day such a bloody name. . At 3 o’olock in the afternoon the Grapevine bridge: and the one above it were destroyed, the 96th Pennsylvania and 3d Vermont breaking down the former. Trees were thrown in every way to obstruct a passage, and in a few momonta such an impassable barrier was reared of logs and trees and brush, added- to the streams of : water and swamp, that no force of ibe enemy could have parsed it in a week..

I cannot dose my acoonnt of the contests across the Chiekahominy without sending you an hum ble tribute to the worth of. one of my High-School ‘ brethren, Lieutenant Jamas F. MoElhone, of com pany C, 14th Regular Infantry. Early in tho no tion at Gaii es’ Mills he received a severe and painful wound, one which , would have sent a less bravo officer to hospital. The enemy were making most tearful onslaughts upon his regiment. Bleeding and almost exhausted he led his com pany Upon them,, rallying around the regimental colors, Volley after volley mowed down tho brave troops, hut still the heroic boy foughton. Half of bis company were killed or wounded, hut at the front of the battle bis sword waved in the sunlight, a beacon to victory. Tho weaker he seemed,' the stronger was his voice, and the more powerful his arm. ne had butene ebjeot, to see the enemy de feated. A brave charge, he in tho front rank, did it, when he sank to the ground, and amid a thou sand plaudits was homo to the rear. Tho last I saw of my schoolmate, ho was wearily journeying towards Savage Station. A soldier of his company, named McGrath, was by his side singing his pfawos and cheering his sorrowful way. Another laurel wreath is woven for tho Philadelphia High School. A HEROIC PICXET PARTY. Whilst one side of the Chiekahominy saw so much blood and battle, the other was not allowed to rest quietly.. During.aH of Thursday and Friday tho most terrific cannonades rent the air. Our artille rists. aware of the evacuation they were so soon to moke, kDew that they could best cover it by fierce and furious shelling. In the midst of all this ball playing, on Friday, two Goorgia brigades oame upon four companies of the 33d New York and three of the 49ih Pennsylvania, who were picketing in front of Fort Davidson, on the extreme right of our position. Our five hundred Unionists fought bravely, making scores of rebels bite the dust. We, of course, retreated, but it was in good order, and with flying colors. Gcnoral Lamar, of the rebels, was killed, and a colonel and. lieutenant oolonel and numerous privates taken prisoners. The bravery of this skirmish, against vastly superior numbers, cannot he sufficiently praised. The week was fall of noble deeds. Friday night found every regiment in, tho army resting on its arms, momentarily expeoting an at tack. The retreat was to be mode by first sending away the wagons, beginning at the left, and going around to tbe right, aßd then the troops from right to left. Saturday morning, June 28, the mtin bodies were sent off, picketers and rear guard alone remaining. All along.the front demonstrations were made by infantry and artillery to blind the enemy. Marches, countermarches, feigned attacks,and every Eort of military manoeuvre were made with endless profurion. The bait took. The foolish enemy never for onepnoment suspected ourreal design, aod, thinking ihese movements demonstrations against them, made for the purpose of weakening the effect of their fancied turning of our right wing,con tinued concentrating their entire army on the Cliiokahominy, and sending tons of thousands of troops across it as reinforcements for the advancing. column. Deluded rebeldom little suspootod. she was sending the flower of her army away from her enemies, SDd that tbe hundred thousand, men she bad aoross tho Chiekahominy had no other foe to fight but a few helpless men, lying in an old house opposite Woodbury bridge. Saturday commenced the evacuation of tho right wing, which was slowly, though snrely made- White House, and all tho stores there, which could not he onrried away, burned. Thirty thou sand Federal muskets wero thrown into the Pa muniy. The mail canao through tjmt morning with newspapers, and Bottom’s bridge and tbe railroad bridge were destroyed as suon as the train passed over. All day the rear guard was march ing and countermarching, still blinding tbe enemy, and in every skirmish with his forces gaining a -victory. Thousands of wagons were sent off on the . road past Savage station, through White Oak Swamp, towards City Point, on tho James river. THE EVACUATION PROCEEDS. All the sick find wounded who could walk wore sont along with the teams—the helpless had to ihift for themselves. I enlisted that day in the squad who hunted sick and sent them away, and at night was with the extreme rear at Wood bury bridge. Never in my life did an evening pass with snob solemn grandeur as that one Bpent at Woodbury bridge. On the Federal aide a solitary cempanyof cavalry guarded the end of the destroyed bridge, and soldiers burned the few vatuable articles which were lying about. Camp-fires were lighted as for a vast army.! Stragglers, tired almost to death, lay on' the ground sleeping, each marked feature sunk into a porfeot rest; A few wagons were still there; The vast plain, once filled with all the pageantry of war, was stretched out before me dotted all over with fires, but having, save that one cavalry company, not a single human being .upon all its surface. Across the river, brightly reflected upon the clouds, were the lights of the rebel camp, and their forces, with no one to oppose them, no . doubt were as they had been for many hours pre viously, under arms upon the bloody field which bore so many of their dead. J( . . WOODBURY BRIDGE EVACUATED. At ten o’olock on Saturday evening, the last of iho Federal army had left Woodbury bridge, and were in full retreat for White Oak Swamp. The night was dark and cloudy, threatening rain. Thousands of straggling soldiers were mixed-up with the wagons, and as we proceeded, regiment after regiment, from all parts'of the right wing, joined us. Through a wilderness of wood and swamp, the dose and damp atmosphere almost suf focating us, we went rushing over logs and stumps, the'men running ;to keep up with-the wagons, and the wagons jolting along in the mo3fc outrageous manner. Midnight brought us to Savage Station, and here was the first horror of that night’s journey. Savage Station was, a large depot of commissary ; stores, and an immense hospital. Sheds and tents by scores had been erected, and were , filled to overflowing with tho sick and wounded, whom ex posure, and battle had rendered helpless. The poor soldiers, - far too numerous to receive any thing like proper care from the very few surgeons who were at their posts, lay on the ground in heaps, huggmfs each other for warmth. Officers and men, ‘ high and low, were; all reduced .to the same level that night. Bach was waiting to have, his wants attended to, and all, I am glad- to say, amid the terrible scenes which surrounded them, bore their agonies niih patience. This horror, however,'was nothing to that which next morning saw. When the rear guard came up, the enemy pressing them on all. sides, the entire hospital was turned out. Sick and wounded were told to shiffcfor themselve® as they best could, and those who could hot got intojthe few ambulances whioh wore there had to walk forward, or, ifpossiblo, persuade some surly teamster to carry them on'his overloaded wa gon. In gloomy squads the lame and halt limped off towards the James river, the groans ;of poor suffering humanity almost stifling the words of; encouragement which the slightly wounded, gave. They shifted for themselves, and many did it by lying down by the roadside to .die. When the enemycame there a fe.w houTS afterwords, even their barbarity must have been mollified by the terrible appearance of Savage Hospital, Do'ad and dying soldiers covered the ground. The ashes of a burning pile of com missary stores, blown about hy the wisd of that Sabbath morning, shrouded them, and the' explo sion of a railroad train; laden with ammunition, ythich was sent shrieking'through the woods, was the knell sounded; for all. , That railroad station will always be a sod spot in my recollection. For' terrible: sights "and scenes, the world has not its equal. ■. , , ; in the hunted Bkirmishes of that retreat.

TURKEY LANDING. Lauding is a rude wharf, some four or jiiboYo City Point, on the Kiohmond bank nes river. A few hogsheads of tobaooo, seemed to be the extent of the trade war, although a rather largo warehouse, ! tastefully decorated, showed the wealth - Turh five mi of tbo sent aw before and judgment of Sts owner. Otherwise it had neither beauty nor attraction. Low and flat, burned alnioat to a cinder by the heat of the sun, it seemed the most uninviting spot in all Virginia, To the tired troops, however, it was a paradise. Here they wereallowed to encamp and find that rest of which they had been for days deprived. The sick and wounded crawled to a strip of wood, and there, after long delays, some attended to their •want*. The stragglers were picked up By the Provost Guard, and pent to their regiments, and quietly and speedily order seemed to come out of the terrible confusion which had reigned supreme for forty-eight hours. REVEL ATTACKS. •' The enemy, finding that their boldest efforts made no impression upon our slowly-retreating rear guard, but that, on the contrary, they only re sulted in defeats, and capture of cannon and pri soners, on Monday conceived a new design. A vast column was sent down the bank of the James river, on the City Point road, with the intention at first of cheeking our advance to the river bank, or if too late for that of flanking our rear guard and euttipg it off. The movement was discovered early in the day, and gunboats went up above Turkey Landing to shell the rebclssosoon as they, were within range. Along came the column raising a terrible dust, and a half dozen gunboats, aided by the signal corps, at once set to work to check it. Prom three o’clock until evening, they kept up a constant firing, every shell falling among the rebels. Thousands must have been killed and wounded, and: a hasty, disorderly; retreat ended the hopes of any early achievement of the wishes of the commander of that column, Monday and Tuesday I spent at the landing, the army steadily passing me on its road down to Harrison’s, and at midnight,,on Tuesday, I recommenced' the weary tramp which was being made by so many of my soldier-brethren. At daylight, • I reached Harrison’s, just below City. Point, which is oil the opposite side of the. river. This was the point ebosen for the encampment of the army, and its gradual restoration from the excessive fa tigue it had undergone, and is to be General MeCleUan’s future source of supply.: The hundreds of vessels, loaded with commissary stores,., which onoe congregated at White House, were there when we came, and every thing was; in readiness to pro vide for the wants of the almost-famished army. Wednesday morning, July 2, was ushered in by a severe and unrelenting northeast storm; which converted everything into mud sad mire. As the weary troops arrived they were forced to pitch their little shelter tents upon this disagreeable sur- face. Bain fell in torrents. The sick and wounded, granted a short rest at Turkey Landing, had again been inhospitably turned out, and were feebly and slowly tramping through the mud, to lie down in it, the rain beating upon them, whilst they waited for the hospital boats. There is always humanity in the army, andnevor did I see.nobler .instances, of it than on the plain pear Harrison’s wharf. Whilst the .poor and helpless men were lying in the mud or listlessly wandering about with despair in every feature, regiment after regiment of troops had their hearts touched and generously gave.up their tents for the woundod to creep under. Two hours raised quite a little town around the head of the wharf, and many a deep sigh showed the grati tude of the soldiers; who had given health and strength to their country. The rain fell faster and mud grew deeper. One eouid scarcely walk and Wednesday night lowered down upon us, per haps the most sad and dreary since the army enter ed the'ficld. On Wednesday and Thursday, every one labored - at ehippibg the wounded and landing commissary . stores.: Steamboat after steamboat passed down the, river, filled to overflowing with troops, only too glad to get into a comfortable resting place. Craft of all kinds landed food, which was at ones sent to the regiments and brigades to feed the hungry. The rebels, too, attacked us; but we captured nu merous prisoners and a battery, and they at length concluded to allow us to enoamp in peace. The rain did hot stop until Thursday at noon, and, of course, the mud became worse and worse. Sunset, on Thursday, however, was clear, and we could safely prophesy better weather. The rain had stopped the forward march of the rebels, even if it were at the expense of our comfort, and the Fourth of July found ns.in good condition, protected by gunboats and earthworks, and prepared to shook any attempt made against us. , : ; , THE RESULT Or THE MOYEKEKT. Though accomplished at an immense.sacrifice of life and property, it is plain that General McClel lan's movement has been a grand success. He.has.. changed bis front'and source of supply. •By the: former he has rcndcred.entireiy useless a series of. rebel earthworks built at an immense expense, and securing an impregnable position. By the lat- • ter lie has released thirty thousand troops from the . duty of guarding his railroad connection with White House. a.bod.v.of jtnennever useful in the •siege of'liicbmond, but who now can be employed with great effect in every opnrat',—, ."e ' enemy. His present position is, a strong ono. White Oak swamp-flanks ‘it on. the right; the . James river, aided by the gunboats, on the left.. Tbo. distance between oannot be more than eight miles. He is rapidly advancing up the Peninsula, being to-day beyond Turkey Station, and within twenty- five miles of the r ebel capital. • .The result in our immediate operations against the enemy has also been most flattering. So one can conceive of the immense slaughter we have made in their ranks in the constant battles from;" Friday, Jane 27, t» Friday, tho 4th of July. Our •course was to fight the entmy all day and retreat at night. Thousands of them were killed ami captured. Every one of onr battles was a Federal victory. The contest at White Oak Swamp was one of the Mood iest battles on record. Four lines of rebels were drawn np in front of our cannon. The second urged the first upon the sea, of flame and smoko at the point of the bayonet, but it was 'oi no avail. Scarcely a man survived to tell the tale -in either line, and the third and, fourth, defying . all the . curses of their officers,- thinking only of, the ; misery they wished to avoid,’broke and fled, and left ns masters of the field. Musket shot, and cannon ball, and gunboat shell poured constantly into reheldom for a week. It almost sickens me to write it, but Na poleon nover caused more blood to flow than has streamed from tho rebel army during this grand retreat. Bat the saddest story is the one which tells our ownlosses. Millions of property were destroyed. Forty pieces of artillery, broken, of course, fell into'the ''enemy's hands. These, however, would have been sacrifices easily made could they have prevented any loss of life. I regret exceedingly that my'duty compels me to tell the truth with regard to, this matter. Thirty; thousand soldiers, and there is the highest military, authority fori stating it, were killed or wounded or captured by the epemy in that one short week’s retreat. The constant battles brought their too rich harvest of dead and dying. Hospitals containing thousands of wounded were given up bodily to the enemy. Sick and wearied soldiers, too tired to proceed, a, step farther, would prawl into out-of-the-way places, be overlooked by our rear-guard, and only wake up from, their sleep to be captured by the enemy. Ten thousand sick and wounded were sent to hos pital down the James river. Our loss has been fearful; but. G?d L General §hipjd§’troops, who are hourly arriving as reinforcements, go a great way in filling up the void. . ' SriSKASAQBMKXT. I cannot close this letter without expressing my firm belief in the mismanagement of things among subordinates in tbo anny of the Potomac. 'Xhe Goyerßinent and country: provides everything on the most ample scale, and hundreds of officers are appointed, especially in the medical department, to carry : out its wishes. This retreat was a great and showed the utter" incom petency of that department. Scarcely an am balance could be found to carry a wounded man, . yet there were enough somewhere to carry all. Not one physician in twenty was at his and the poor, soldiers screaming with the agony of their wounds, went for days without hav ing them dressed. Thousands sick and wounded, who should now be safe in hospitals at the North, have fallen into the enemy’s hands, through ' the neglect of popinjay, surgeons. Many have died be cause their wants never were cared for. And even now, hundreds on the hospital boats are moaning and groaning with festering wounds, which have not received the slightest attention. A searching investigation and prompt punishment of those -men w.ho have violated the honor of their cloth in thus neglecting the afflicted, will do much to restore the confidence and alacrity of the troops. J- 0. Steams a John A. Warxeh, Os tub James Kiveh, July 5,1562. This morning, at 10 o’clock, when I - left Harri son’s bouse. General McClellan’s furthest advanced post was within twenty-five miles of Richmond, and he was rapidly pushing them forward, driving the. enemy at all points,; His army had completely re covered- from th*o fatigue caused by the retreat, and be had been strongly reinforced. Gunboats accompanied his advance, shelling the woods, and scattering the enemy, and his tnain forces were following at safe supporting distances. His position was one whioh could hot be flanked by the enemy, the James river and gunboats flanking it on the left, and the lower end of White Oak Swamp on the right, and three miles in length of laading-plaoes on the river were amply sufficient to secure full Supplies of every thing needed by the army. The river was full of transports, loaded with am munition, and the genial weather—neither extreme of temperature bolding sway—will prove the best reinforcement General McClellan- couid wish. ■ The capture of Richmond, from this; position, will very likely be a tedious operation, requiring great skill.and anovornholming force: The Fede ral army has twenty-five miles of rebel country to overcome, ami it may take as long a time as it did to cross the Peninsula from -White'.-House to.

Tour conduct ranks you among the celebrated armies of history, No one will now question that each of you may always with pride say, “I belong to- the army of the Potomac.” Ton have reached this new base complete in or ganization and unimpaired in spirit.
