sought to flank them out of position, thereby fighting on more open ground. After the reorganization Couch continued to lead the II Corps, with his divisions commanded by Hancock and French (both now major generals) and Brig. Gen. John Gibbon at the head of Howard's former division, a total of about 17,000 soldiers. During the ensuing Chancellorsville Campaign Couch was the senior corps commander, making him Hooker's second-in-command. In late April, Hooker began moving his corps across the Rappahannock and Rapidan Rivers, ordering two of Couch's divisions to entrench and defend the Banks's Ford crossing of the Rappahannock and detach Gibbon's 5,000 men to remain at the Union camp back at Falmouth on April 29. The following day Couch had cleared the ford and was marching toward Chancellorsville. In the afternoon of May 1 Hooker—normally quite aggressive—cautiously slowed his marching army, and soon he stopped their movement altogether, despite some success against the Confederates and the loud protests of his corps commanders. Couch sent Hancock's division to bolster the Union men already engaged, and informed Hooker they could handle the enemy in front of them. However, Hooker's orders stood; march back into the positions they held the previous day and assume a defensive posture. Couch complied and ordered Hancock's division to form a rear guard as they withdrew. As Hancock formed his men, Couch could see Confederate artillery aiming for the massed Union columns, and he told his staff "Let us draw their fire." The group of mounted officers clustered around a clearing where the enemy cannon could easily view them, thus attracting their fire and sparing the marching infantry; Couch and his staff also went unharmed. By nightfall the Union soldiers were busy fortifying the ground. Couch formed his divisions behind the XII Corps in roughly the center of Hooker's line. By late afternoon on May 2, Hooker's line was hit on the right (the XI Corps led by Howard) by Confederates under Lt. Gen. Thomas Jonathan "Stonewall" Jackson, and despite resisting the XI Corps was routed and ran toward Chancellorsville. The remaining corps tightened into a "U" shaped formation by May 3, and Confederate artillery began shelling their positions, including Couch's men. At about 9 a.m. that day Hooker was stunned by enemy fire when a shell hit the pillar he was leaning on, temporarily incapacitating him within an hour. At that time Hooker turned command of the
