Welcome to the Ninth Regiment Connecticut Volunteers: A CT Civil War Memorial

The Ninth Regiment Connecticut Volunteers (Connecticut’s “Irish Regiment”) was organized in New Haven in September of 1861. They were transported to Ship Island, MS on the Gulf Coast by the end of the year where they saw action as well as in New Orleans the following spring. During the summer of 1862 they were part of the first campaign against Vicksburg and assigned to the “Williams Canal” operation, an unsuccessful Federal project to divert the course of the Mississippi River, bypass Confederate guns at Vicksburg and win control of the Mississippi. Beginning there the regiment lost 150 men due to the lack of supplies, heat, dysentery and malaria conditions in a four month period. At Baton Rouge Colonel Thomas Cahill of the Ninth took command of the Federal troops after the death of Brigadier General Williams and successfully repulsed the Confederate attack. After being assigned to defend New Orleans they later served in Virginia’s Shenandoah Valley and played a prominent role in General Sheridan’s 1864 victory at Cedar Creek.


This website is intended to provide a history of the Ninth (1861-1865) as well as some soldier’s stories, information on the makeup of the Ninth, a listing of known gravesites, a description of regimental flags and various newspaper histories. In addition a review is provided of the Ninth’s monument dedicated in New Haven in 1903 and the Connecticut monument honoring the Ninth Regiment dedicated at the Vicksburg National Military Park in October of 2008.
