Mustering in there that same day as a private, he became part of Company G in the 95th Pennsylvania Infantry Regiment (also known as the 95th Pennsylvania Volunteers).

Gettysburg. Arrested on September 2, 1863, he was later sent back to his unit, where he remained until he was transferred October 14, 1864. It was during this period of service that he demonstrated such bravery that he was awarded his nation's highest award for valor, the U.S.
Medal of Honor. He was then honorably discharged from military service on November 18, 1864. He died on February 9, 1904, and is interred at
Mount Moriah Cemetery in Philadelphia, Pennsylvania. ==Medal of Honor citation==
