Leaving a large detachment under Sedwick in front of Fredericksburg, Hooker marched a flanking column around, and, behind the Confederates. Lee left a small unit to met Sedwick and marched westward to meet Hooker. Hooker, dropped the inititive and entrenched at Chancellorsville at the Chancellorsville Inn. Lee again divided his army, sending Stonewall Jackson on May 02 out to flank Hooker's right. If one evaluates the battle map of the day, Jackson left the biovouac on Furnance Road, over to Brock Road, past the Burton Farm, and, up to Plank Road (above Orange Plank Road). The attack and severe fighting on May 03 drove Hooker back to a rear position, the apex of his line being located on Elys Ford Road. His last recourse was the Rappahanock and Rapidan Rivers by way of U.S. Ford Road. Reminded me of Moses being trapped at the Red Sea!! With the confusion of the day, there was certainly enough of blame to go all way around...Hooker first, the Staff coming in second. When Jackson approached Lee at three in the morning on May 02 and asked for the troops he needed, Lee thought a moment, agreed, knowing the risk and ended the conversation with "Well, go on then." He had to trust Jackson. I doubt there was much of an "element of surprise" and thus, the Union troops were routed, fair and square.
