The 72nd New York Infantry Regiment was one of five infantry regiments formed by former U.S. Congressman Daniel Sickles and established as part of the Excelsior Brigade which fought with the Union Army during multiple key engagements of the American Civil War, including the Chancellorsville Campaign in Virginia, the Battle of Gettysburg in Pennsylvania, and the Overland Campaign. Leaders from the 72nd New York recruited men from New Jersey, as well as from cities and small towns across the State of New York.
