The battle began at three o'clock, and raged with fury till nine o'clock. There were no movements in the Union lines. The men stood in their places and poured an uninterrupted fire upon the enemy, who were vainly endeavoring to cross the ravine and scale the heights. The artillery, fifty pieces, rained solid shot, shells, grape, canister, shrapnel, all sorts of missiles, producing great slaughter. General D. H. Hill arrived with his division, and joined in the attack upon Seymour at the Mills, but was received with a "murderous fire."[37] [Footnote 37: Confederate Narrative, Rebellion Record, Vol. V. p. 250.] The united efforts of the two Hills and General Branch were not sufficient to dislodge the two brigades which held the position. Griffin, Martindale, and Meade were ready to lend assistance, but were not engaged. Griffin only fired a few shots. The Union loss was eighty killed and about two hundred wounded. The Rebel loss is supposed to have been nearly three thousand. The assaults upon the rifle-pits were made with great desperation, but the men could not get through the impassable abattis, and were cut down by the constant and steady fire of musketry and canister at short range. But the advance of General Jackson by Coal Harbor made it necessary to withdraw the troops from this strong position and concentrate the entire force on the north bank, to cover the bridges which had been constructed between the two wings of the army. During the night General McCall's division was withdrawn, contrary to the remonstrances of the brave men who had held the ground against five times their force; but they did not know that Jackson was on their rear with 40,000 men. General McClellan ordered the heavy guns and all the baggage to be sent across the Chickahominy. He had already meditated a retreat to the James River. "Run the cars to the last moment, and load them with provisions and ammunition. Load every wagon you have with subsistence, and send them to Savage Station," was the order sent to Colonel Ingalls, the Chief Quarter-Master at White-House. THE BATTLE OF GAINES'S MILLS. The battle which was fought on the 27th of June is known in the South as the battle of Coal Harbor; in the North, as the battle of Gaines's Mills. General Fitz-John Porter commanded the Union troops, and General Lee the Rebel army.
