"The Advance Guard of the Grand Army of the United States Crossing the Long Bridge Over the Potomac at A.M. on May 24, 1861" is a wood engraving by Winslow Homer, depicting the Union Army's advance across the Potomac River during the American Civil War. The scene is rendered in a realistic style, with a focus on the soldiers' determination and the dramatic setting of the bridge. This piece, created early in Homer's career, demonstrates his skill in capturing the human cost of war, which would become a recurring theme in his later work.
