Allan Pinkerton, President Lincoln, and Maj. Gen. John A. McClernand Photo

Allan Pinkerton, President Lincoln, and Maj. Gen. John A. McClernand; Antietam, Md.
Photograph from the main eastern theater of the war, Battle of Antietam, September-October 1862.

At Antietam (or Sharpsburg), on Sept. 19, 1862, the casualties numbered 23,000-- nine times greater than those of D-Day in World War II.

The Union victory turned back Gen. Lee's invasion of the North, negated his intent to get Lincoln to sue for peace, and provided a rationale to declare the abolition of slavery.

Gen. McClernand commanded the 1st Division of the 8th Illinois Volunteer Regiment, which fought at Ft. Donelson and Shiloh.

In 1861, Allan Pinkerton thwarted a plot to assassinate Pres. Lincoln, and, at the President's request, started the Secret Service. His Operatives later used a double agent to uncover a Confederate plan to free 8,000 prisoners of war.

Two versions of the photo were made. Above is the other known photograph.


Many existing Civil War photographs were taken under the supervision of Mathew B. Brady, who at the time had acquired a reputation as one of America's greatest photographers. He spent most of his time during the war supervising his corps of traveling photographers, preserving their negatives and buying others from private photographers freshly returned from the battlefield, so that his collection would be as comprehensive as possible.

Below is blowups of President Lincol's face in the above photos.
