The National troops fell back to Savage's Station, where later in the day Magruder attacked them again. He had a rifled cannon mounted on a platform car, with which he expected to do great execution. But there was an ample force to oppose him, and it stood unmoved by his successive charges. About sunset he advanced his whole line with a desperate rush in the face of a continuous fire of cannon and musketry, but it was of no avail, and half an hour later his own line was broken by a counter charge that closed the battle. He admitted a loss of four thousand men. Sumner and Franklin, at a cost of three thousand, had thus maintained the approach to the single road through White Oak Swamp, by which they were to follow the body of the army that had already passed. But it was found necessary to burn another immense quantity of food and clothing that could not be removed, and to leave behind two thousand five hundred sick and wounded men.

A.] Jackson, after spending a day in building bridges, crossed the Chickahominy and attempted to follow McClellan's rear guard through White Oak Swamp; but when he got to the other side he found a necessary bridge destroyed and National batteries commanding its site, so that it was impossible for his forces to emerge from the swamp. But meanwhile Hill and Longstreet had crossed the river farther up stream, marched around the swamp, and struck the retreating army near Charles City Cross-Roads, on the 30th. There was terrific fighting all the afternoon. There were brave charges and bloody repulses, masses of men moving up steadily in the face of batteries that tore great gaps through them at every discharge, crossed bayonets, and clubbed muskets. Only on that part of the line held by McCall did the Confederates, with all their daring, succeed in breaking through. McCall, in his report, describes the successful charge: "A most determined charge was made on Randol's battery by a full brigade, advancing in wedge shape, without order, but in perfect recklessness. Somewhat similar charges had been previously made on Cooper's and Kern's batteries by single regiments, without success, they having recoiled before the storm of canister hurled against them. A like result was anticipated by Randol's battery, and the Fourth Regiment was requested not to fire until the battery had done with them. Its gallant commander did not doubt his ability to repel the attack, and his guns did indeed mow down the advancing host; but still the gaps were closed, and the enemy came in upon a run to the very muzzles of his guns. It was a perfect torrent of men, and they were in his battery before the guns could be removed." General McCall himself, endeavoring to rally his men at this point, was captured and carried
