Colonel William R. Brewster
Colonel William R. Brewster commanded the brigade at Gettysburg. Brewster was originally from Connecticut but was living in New York at the start of the war. He became major of the ninety day 28th New York State Militia, then colonel of the 73rd New York in Daniel Sickles’ Excelsior Brigade. The death of Hiram Berry and the court martial of Joseph Revere at Chancellorsville brought Brewster to command of the brigade as senior colonel. Brewster would continue to command the regiment or the brigade except for bouts of illness until the regiment mustered out in December of 1864.
