The Rebels made no attack on Saturday. They were compelled to repair the bridges which had been destroyed, before they could cross the Chickahominy. General Sumner commanded the rear-guard. He retreated slowly on Saturday to Peach Orchard, and halted to destroy the supplies. On Sunday morning a portion of Lee's army advanced to attack Sumner, who was at Peach Orchard and Allen's Farm; but Hazard's and Pettit's batteries, with Sedgwick's division, quickly repulsed them. BATTLE OF SAVAGE STATION. Lee's divisions, one after another, filed across the hastily repaired bridges. General Franklin was north of the railroad. He saw them, and sent word to General Sumner, who fell back with Franklin to Savage Station. General Franklin was on the right, Sumner in the center, and Heintzelman nearer Richmond on the left. There was a misunderstanding of orders; and General Heintzelman moved across White-Oak Swamp, which exposed Sumner's left flank to the enemy. Through the long Sabbath hours, these troops stood upon the wide plain facing northwest, seemingly motionless almost as statues, while the long wagon trains moved into the woods towards the south. They were the rear-guard, and on them depended the salvation of the army. Following the wagons were thousands of sick and wounded, working their way towards the swamp, urged on by hope of escaping the hands of the Rebels. It was heart-rending to hear the words of those who were too badly wounded to be moved, or who could not be taken away. The sun went down. Evening was coming on, yet the twenty thousand men remained upon that field awaiting the attack,--three lines of resolute, determined men. Brooks's, Hancock's, and Burns's brigades were in front; with Osborn's, Bramhall's, Hazard's, and Pettit's batteries,--twenty-four guns. It was past five o'clock before the enemy opened the battle. An hour passed of constant artillery firing. Then the Rebels advanced across the wide and level plain with yellings and howlings. There was a stream of fire from Sumner's line,--a steady outpouring of deadly volleys. It was twenty thousand against forty thousand. There were answering volleys from the Rebel lines. Sumner's batteries left off firing shell and threw canister, and the lines, which had advanced so triumphantly, were sent in confusion across the field. Again they advanced, and were again repulsed. Longstreet and Jackson, once more under cover of the gathering darkness, urged on their reluctant troops. Sumner brought up his reserve brigades. It was a short, sharp struggle,--a wild night-tempest,--the roaring of fifty cannon, and thirty thousand muskets. The evening was unusually calm. Not a breath of air stirred the leaves of the trees. The stars shone brightly. Strange the scene,--so weird and terrible upon that plain! A thousand men dropped from the Union ranks, and thrice that number from the ranks of the Rebels.
