He enlisted in the Union Army shortly after the start of the war and, as a private in the 18th Regiment Massachusetts Volunteer Infantry, participated in several major battles, including Antietam, Fredericksburg, Chancellorsville, and Gettysburg.  He was awarded the Medal of Honor for capturing a Confederate battle flag during the Battle of Globe Tavern on August 21, 1864.  Transferred to the 32nd Regiment Massachusetts Volunteer Infantry and wounded in the Siege of Petersburg, he returned to the field in time to witness the Confederate surrender at Appomattox Court House.  After the war, he returned to Massachusetts, working and raising a family until his sudden death at age 40.

When the 3rd and 4th Massachusetts were mustered out in July 1861, the seven companies that had signed on for three years were grouped together to form a battalion known as the Massachusetts Battalion.  Finally, in December 1861, three more companies were added to their roster to form a full regiment and the unit was designated the 29th Massachusetts.
