The Regiment was attached to the Army of the Cumberland, and arrived in time to join the Battle of Perryville, which ended the Confederate incursion in Kentucky. During the battle, the 24th was assigned to defend a cannon battery, which came under assault from a Confederate brigade, lead by Daniel Weisiger Adams. The attack was repulsed, and Larrabee was commended by his brigade commander, Colonel Nicholas Greusel, for his leadership in the defense of the battery.
