At the Battle of Secessionville, PVT Herbert W. Beecher and the 1st Connecticut Light Artillery Battery supported the advance of the 2nd Division upon the Tower Battery on James Island with their 4x 14-inch James Rifles. Though the Confederate Artillery mostly focused on the several infantry advances upon the Tower Battery, they eventually dueled with the men from Connecticut.
