During their existence between September 1, 1862 to June 20, 1863, the 25th New Jersey Volunteer Infantry Regiment fought in several engagements as part of the Army of the Potomac. These engagement included the Union loss in the Battle of Fredericksburg and the inconclusive Siege of Suffolk. Despite the losses, Derrom was cited by several of his superiors for exemplary engineering and bridge-building assignments, although his name now appears in Civil War databases incorrectly as "Andrew Derron".
