Lincoln visits with his generals
After the Civil War battle of Antietam, President Abraham Lincoln was anxious for Major General George B. McClellan to pursue Confederate General Robert E. Lee’s army into Virginia. McClellan believed that his army was not fit to move. Lincoln unexpectedly visited McClellan and his army to observe its condition. On October 3, 1862, Alexander Gardner photographed Lincoln and McClellan at the Fifth Corps headquarters.
