Detail: After the defeat at Second Bull Run, it was clear that the war would not end quickly. Lee’s daring move into Maryland and Pennsylvania led to the Battle of Antietam on September 17, 1862, the single bloodiest day in United States military history. The Thirteenth New Jersey regiment and the First Artillery Battery engaged in the worst of the fighting at the Antietam Creek near Sharpsburg, Maryland. Washington Roebling served as an engineer officer on General Hooker's staff during this battle. The following day, he drew this map, which shows landmarks, residences, roads, and fords across Antietam Creek, movements of Hooker's advance, and placement of Union forces. Notations in Washington's handwriting read "cornfield," and "place where Hooker was shot in the foot."

Detail: Washington Roebling of Trenton, son of engineer John A. Roebling and future builder of the Brooklyn Bridge, enlisted as a private in Company A of the New Jersey State Militia in April 1861, resigning a few months later to enlist in the Sixth New York Independent Battery. He was later promoted to the rank of sergeant, and then to second lieutenant in January 1862. During the war, he built suspension bridges, made maps, and did reconnaissance from a hot-air balloon. He saw action at the battles of Second Bull Run, Antietam, Chancellorsville, and Gettysburg, where he helped to secure Little Round Top, as well as the Battle of the Wilderness, Spotsylvania Court House, and the Crater. In 1865, he was commissioned Colonel, U.S. Volunteers, by brevet for "gallant and meritorious services during the war."
