When I returned to my command in the early part of March, after a long absence as a prisoner, I was greatly depressed at the sad state of feeling in which I found almost the whole army.--The buoyant, hopeful tone that animated them during the bloody and heroic struggles in the Wilderness, and at Spotsylvania, was gone. The men who followed the immortal Jackson in his historic and eventful campaigns, and endured every fatigue and hardship without a murmur, in the full hope of eventual victory, were dejected, crestfallen and despondent. The wear and tear of a continuous campaign from the Rappahannoc to the James, and the disasters of the Valley struggle of the previous fall, together with the continuous marching and counter-marching on their present lines, without rest and with short rations, were telling upon their hardy natures. Longstreet's veterans, who had followed their old leader from the ensanguined fields of Virginia to Chicamauga and East Tennessee, and who had again been forwarded to their old fields of conflict, were thinned in numbers, and had lost much of the fierce fire of pluck that characterised them of old. The lines were long, stretching from below Richmond, on the north side of the James, to Hatcher's run, away beyond Petersburg, on the south side. A countless host were just in front of them, watching an opportunity to strike where the lines were the weakest.--The Confederate army numbered perhaps 60,000 all told--artillery, cavalry and infantry, and with 40 miles of defence, the battle-line was thin as a skirmish, and the duty incessant and fatiguing in the greatest degree. On some parts of the line the crack of the rifle, the booming of artillery, and the bursting of the mortar shells were incessant. Desertions were very numerous, both to the enemy and to the rear, and I early found that the army had at last succumbed, not to the enemy in front, but to the discontent, the murmurings, despondency and demoralization among the people at home, who infused their hopeless dejection, by furloughed men returning to their commands, and by letters. Longstreet commanded the Confederate left, across the James, and his right division extended to within a few miles of Petersburg. Gordon came next, with his three divisions, thinned by arduous and fatiguing marches and bloody battles in the Shenandoah Valley, to the dimensions of only respectable brigades. He commanded just in front of Petersburg, from the Appomattox to a small stream just to the right of the city, which, not knowing its correct name, I will call Silver run; and it was along this line, almost its entire length, that a continuous struggle for months had been kept up, and in some places the opposing forces were scarce a dozen yards apart. A. P. Hill, with his three divisions, held the right, extending to Hatcher's run, while the cavalry guarded either flank.
