Jackson and his command arrived late in the afternoon. However, unable to find A.P. Hill or D.H. Hill, Jackson did nothing. Although a major battle was raging within earshot, he ordered his troops to make camp for the evening. Hill's 11,000 men, most of them green regiments who had never fired a shot in battle, launched a series of futile attacks over the next few hours. The brigade of John R. Anderson assaulted the Union right flank, with James Archer's and Charles W. Field's brigades in support. Maxcy Gregg's brigade was held in reserve and did not participate in the battle at all. Directing his troops, John Reynolds gestured at the oncoming mass of Confederates and told a staffer "There they come like flies on a piece of gingerbread." The Union artillery and musketry tore enormous gaps in the Confederate lines as they attempted to cross the creek. Although A.P. Hill had 24 guns with him, he made no attempt to use massed artillery fire to counter the Union gunners, instead sending individual batteries in support of the infantry, most of which were quickly put out of action by enemy shelling.
