Service
Drum, Company B
The 40th New York was mustered at Yonkers, New York, on June 27, 1861, sponsored by the Union Defense Committee of New York City by special authority from the War Department. Originally, the regiment was to be raised as the United States Constitution Guard by Colonel John S. Cocks of the 2nd New York but organization was not completed. With additional sponsorship by the Mozart Hall Committee it adopted the name Mozart regiment. Despite being a New York Regiment, only the original Constitution Guard were New Yorkers. The regiment was completed by taking four companies from Massachusetts and two from Pennsylvania. On September 6, 1862, the regiment absorbed the enlisted men of the 87th New York Volunteer Infantry Regiment. On May 30, 1863, it absorbed the three-year enlistees of the 37th New York, 38th New York, 55th New York, and 101st New York. On August 3, 1864, the regiment absorbed the 74th New York.
At the Battle of Fair Oaks (Seven Pines) the 40th New York gained considerable recognition for its action on June 1. The regiment's commander, Colonel Edward J. Riley, was kicked in the head and thrown by his horse prior to the battle, removing him from the front. Lt. Col. Thomas W. Egan led the regiment into battle on May 31, and on June 1 ordered a bayonet charge into the 5th and 8th Alabama regiments. The Mozart Regiment suffered 96 casualties, including every member of the color guard killed or wounded. Following the death of Color Sergeant Joseph Conroy, Color Corporal Robert Grieves, himself severely wounded, planted the flag far out in front of the regiment, before being ordered by Egan to withdraw.[1]
Gettysburg, Second Day
Monument at Gettysburg
The 40th New York played a critical role in the defense of the Federal left flank during the second day at Gettysburg, delaying the approach of Law's Division to Little Round Top. Below Devil's Den, the men of the 40th New York were called upon to delay at all costs elements of Benning's Georgia brigade and Law's Alabama brigade, as Confederates began forcing back Hobart Ward's 2nd Brigade of the Third Corps. The 40th New York charged seven times down the course of Plum Run, into the boulders of Devil's Den and the Slaughter Pen.[2]
