Battle of Princeton
John Trumbull used Mercer's son, Hugh Jr., as a model for his painting "The Death of General Mercer at the Battle of Princeton, January 3, 1777". A portrait by Charles Willson Peale entitled "Washington at the Battle of Princeton, January 3, 1777" displays Washington in the foreground with Hugh Mercer lying mortally wounded in the background, supported by Dr. Benjamin Rush and Major George Lewis holding the American flag. This portrait is the prize possession of Princeton University. James Peale painted a version of "Battle of Princeton" which shows in the background a very indistinct portrait of Mercer being helped from the ground.
