As soon as Early's withdrawal from Maryland had quieted all apprehensions for the safety of Washington, the orders that had met the advance of the Nineteenth Corps at Hampton Roads were recalled, and, reverting to his original intention, Grant sent the detachments of the corps as they arrived up the James River to Bermuda Hundred to join the right wing of his armies under Butler. Indeed, at the moment of its arrival at Poolesville, the First division had been ordered to take the same destination, but this the movements of the contending armies prevented. The first of the troops to land at Bermuda Hundred was the 15th Maine on the 17th of July. It was at once sent to the right of the lines before Petersburg, and within the next ten days there were assembled there parts of four brigades--McMillan's and Currie's of the First division, and Birge's and Molineux's of Grover's. Part of Currie's brigade was engaged, under Hancock, in the affair at Deep Bottom on the north bank of the James on the 25th of July, losing eighteen killed and wounded and twenty-four prisoners. The work and duty in the trenches and on the skirmishing line were hard and constant, reminding the men of their days and nights before Port Hudson, but this was not to last long, and the loss was light.(2) On the 20th of July at Carter's Farm, three miles north of Winchester, Averell, who was following Early, met and routed Ramseur, who had been sent back to check the pursuit. Early continued his retreat to Strasburg on the 22d, but when the next day he learned that Wright was gone, he turned back to punish the weak force under Hunter, and on the 24th overwhelmed Crook at Kernstown. Crook retreated through Martinsburg into Maryland, and marching by Williamsport and Boonsborough, took post at Sharpsburg, while Averell stayed at Hagerstown to watch the upper fords of the Potomac. To break up the Baltimore and Ohio railway and to ravage the borders of Pennsylvania were favorite ideas with Early. He now entered with zest on the unopposed gratification of both desires, and while he himself bestrode the railway at Martinsburg with his army engaged in its destruction, he sent McCausland with his own brigade of cavalry and Bradley Johnson's on the famous marauding expedition that culminated in the wanton burning of Chambersburg in default of an impossible ransom, and at last resulted in the flight of McCausland's whole force, with Averell at his heels, and its ultimate destruction or dispersion by Averell, after a long chase, at Moorefield far up the south branch of the Potomac. When on the 23d of July he saw Wright back at Washington and Early at Strasburg in retreat, as was imagined, up the valley, Grant partly changed his mind about recalling the troops he had spared for the defence of Washington, and determining to content himself with Wright's corps, directed Emory to stay where he was. Emory now had 253 officers and 5,320 men for duty.
