A Seventh Connecticut Volunteer Infantry Regiment served in the Union Army during the Civil War. Most of its enlistment was in the Department of the South, but after early 1864, it was transferred to Virginia to join the Army of the Potomac and the Army of the James. It finished the war in North Carolina. Early in its history, it successfully invaded Tybee Island from the sea and captured Hilton Head in preparation of a landward assault on Charleston, South Carolina. After a brief skirmish that saw it defeated by a superior rebel defense, no further assault was attempted by land. Faced with hardships due to the loss of its support ships to a storm and treacherous terrain, the regiment was transferred to engagements elsewhere.
