Mason A. Rea was 27 years old from Readville, MA when he was commissioned a 1st lieutenant in Company K of the 24th Massachusetts Infantry Regiment on September 2, 1861. The 24th was part of Burnside's Expedition to North Carolina and fought at Roanoke Island and New Berne in February and March of 1862. The majority of the regiment spent the balance of 1862 in North Carolina, moving to South Carolina in early 1863. The regiment was temporarily returned to the Virginia theater in the spring where they fought at Chancellorsville, before returning to South Carolina. There they participated in the action against James Island and then Morris Island, including the assault on Battery Wagner and its subsequent siege. In early 1864 many of the veterans, including Rea reenlisted and received a Veteran's Furlough with the balance of the regiment being moved to temporary duty in St. Augustine. In late April the regiment was sent to Virginia, where they participated in the battles of The Bermuda Hundred and Drewy's Bluff. It was at this battle that Lt. Rea was killed on May 16, 1864.
