"Everything goes on prosperously. The intelligence of the men is a great surprise to me. They learn all the details of guard duty and camp service infinitely more readily than most of the Irish that I have had under my command. There is not the least doubt that we will leave the State with as good a regiment as any that has marched."Shaw was promoted to major on March 31, 1863, and two weeks later on April 17 was made full colonel. On April 30 the regiment drew 950 Enfield rifled muskets and swords for non-commissioned officers (NCOs). By May 11 more troops had arrived in Boston than were required to man the regiment. The 55th Massachusetts was begun with the next round of new recruits.
