The forerunner of the 16th Infantry, the 1st Battalion, 11th U.S. Infantry, fought in almost every major campaign of the Army of the Potomac during the Civil War. During that conflict, the regiment earned 12 campaign streamers and engaged in numerous battles and skirmishes. In almost every major battle, the 11th US Infantry was in the thick of the fighting, and as part of Major General George Sykes’ divison of Regular Army regiments, the 2nd Division, V Army Corps, it was responsible for helping to avert destruction of that Army on several occasions. Arguably the regiment’s most significant action was that of Gettysburg on 2 July 1863 when it lost almost half its strength in the fighting to help stop Longstreet’s Confederates from taking Little Round Top and rolling up the Army of the Potomac’s left flank. Provided in these galleries are images of the men who laid the foundation for making the 16th Infantry one of the finest regiments in history and of locations where they built that reputation.
