Lee quickly moved his army into the position thus relinquished, and began feeling the Federal lines with skirmishers and some cannonading during the evening of May 1st. By the next morning the two armies were in line of battle.

But Lee threw the hopes of success into one great and decisive blow at Hooker's host.

Early in the afternoon, Hooker by a ruse was beguiled into the belief that Lee's army was in full retreat. What Hooker had seen and believed to be a retreat was the marching of Jackson's forces, about twenty-six thousand strong, from the battlefield. What he did not see, however, was that, after a few miles, Jackson turned abruptly and made for the right flank of the Federal host, the Eleventh Corps, under Howard.

The Confederates fought heroically. The knowledge
