Overview

The 69th New York Infantry (Three Years’ Service) was an infantry regiment organized in New York City and mustered into United States service from September 7 to November 17, 1861. It served as the 1st regiment of the Irish Brigade, drawing its ranks primarily from New York City, with additional members from Chicago, Brooklyn, and Buffalo. The regiment fought for the Union in the Eastern Theater and became known for its high casualty rates and distinguished service in major campaigns of the Army of the Potomac.

This unit is distinct from the 69th New York Infantry (Militia).

Organization & Service

The 69th New York Infantry (Three Years’ Service) was mustered in at New York City between September and November 1861. The regiment departed for Washington, D.C., on November 18, 1861, and was stationed at Fort Corcoran. In December 1861, it became part of the Irish Brigade under Brigadier General Thomas Francis Meagher.

During the Peninsula Campaign in spring 1862, the regiment was attached to the 2nd Brigade, 1st Division, 2nd Corps, Army of the Potomac. Its first engagement occurred at Rappahannock Station, followed by participation in the Siege of Yorktown and the Battle of Fair Oaks. The regiment was heavily engaged throughout the Seven Days’ Battles, suffering significant losses. At the Second Battle of Bull Run, the division arrived after the main fighting. At Antietam, the 69th fought at the “Bloody Lane,” incurring heavy casualties. The regiment then moved to Fredericksburg, where it participated in the assault on Marye’s Heights and again sustained severe losses.

After wintering near Falmouth, the regiment was active in the Chancellorsville Campaign and fought at Gettysburg, Auburn, Bristoe Station, and during the Mine Run Campaign. Due to heavy losses, the regiment was consolidated into two companies in June 1863. Many men reenlisted as veterans in late 1863 and early 1864, and new recruits joined, allowing the regiment to continue as a veteran unit.

In 1864, the 69th participated in the Overland Campaign, including the Wilderness and Cold Harbor, and suffered further losses during the initial assaults on Petersburg. The regiment remained before Petersburg during the siege and was engaged at the Weldon Railroad, Strawberry Plains, Reams’ Station, Hatcher’s Run, and throughout the Appomattox Campaign. The regiment was mustered out at Alexandria, Virginia, on June 30, 1865.
