On October 1, 1862, Lincoln took the train from Washington and reached McClellan’s camp on the banks of the Potomac River. This was his most determined effort to date to persuade McClellan to take action. During the three days Lincoln spent in the army camp, he was photographed numerous times, with the most famous ones showing him with McClellan and his staff.
One of the most famous photographs ever taken of President Lincoln is this one of him at Antietam meeting with General McClellan. A young George A. Custer is seen at the far right.
