Daniel Sickles
On June 27, Hooker resigned as commander of the Army of the Potomac. Among the corps commanders suggested to replace him, the New York Herald actually suggested Sickles as the best commander for the job. On June 28, three days before the battle of Gettysburg, Lincoln appointed general George G. Meade to replace Hooker. On July 1, the first day ended in Confederate victory. Meade worked to quickly put his forces in place for the next day's battle. Early on the morning of July 2, Meade sent a message to Sickles with instructions to place his 12,000-man corps on Cemetery Ridge. He was specifically ordered to connect to general Winfield Scott Hancock's II Corps on his right, and extend his line to Little Round Top on his left.
