Battery B brought 114 men to the field serving four 10-pounder Parrott Rifles. It was commanded from July 2-3 by Captain James McKay Rorty.
Rorty had been Second Corps Ordnance Officer, but had persuaded General Hancock to give him a combat command for the battle, and he took over Battery B from Lieutenant Sheldon on July 2nd, probably in the afternoon before Longstreet’s assault.
On Juy 2 the battery fought near the Wheatfield before being withdrawn to the line of batteries set up by Lt. Colonel Freeman McGilvery along Plum Run. It lost one man killed and eight wounded, as well as 13 horses killed or disabled.
On July 3 the battery was placed on Cemetery Ridge just south of the Copse of Trees – directly in the path of Pickett’s Charge. The intense bombardment before the charge disabled three of the four cannon of the battery, blowing one from its carriage. Captain Rorty dropped his sword belt and coat and grabbed a sponge staff to help work the remaining gun. He shouted a desperate plea to Colonel Arthur Devereau of the nearby 19th Massachusetts Infantry for a dozen men to help work his guns, and was rewarded with a score of volunteers. Lieutenant Moses Shackley risked his life to fill a sponge bucket from a nearby spring to keep the gun firing.
Captain Rorty was killed and Lieutenant Sheldon wounded as the final charge of Confederate Brigadier General James Kemper’s Virginians swept up and over the battery. Sergeant Lewis Darveau shot a Confederate captain who had placed his colors on one of the guns, brained him with a handspike, and was in turn shot down.
Captain Rorty, Sergeant Darveau, Privates John Barry, Michael Halloran, Patrick Kelley, Amos Maynard, Charles Radue, Henry Rosegrant, Napoleon Twitchell were killed or mortally wounded and 16 men were wounded. Lieutenant Robert E. Rogers then took over the battery.
