The Battle of Fredericksburg was fought from December 11th to December 15th, 1862. Among the 120,000 or so Union soldiers in the Army of the Potomac was a 36 year old French-Canadian immigrant named Moises Beaulieu. Moises had enlisted in June 1861 in Company A of the 11th Massachusetts Volunteer Infantry Regiment (sometimes known as the Boston Volunteers) and thus had already been in the Union army for some 18 months when he found himself on the bank of the Rappahannock River across from the town of Fredericksburg, Virginia. Major General Ambrose Burnside, a Rhode Islander who had risen from Colonel of the 1st Rhode Island to commander of the army, was waiting for pontoons to arrive so bridges could be built across the river. At that time the 11th Massachusetts was in Brigadier General Joseph Carr’s brigade, of Brigadier General Dan Sickles’ Second Division of George Stoneman’s Third Corps, part of the Center Grand Division commanded by Major General Joseph Hooker.
