Battle of Gettysburg

The 147th New York was commanded at the Battle of Gettysburg by Lieutenant Colonel Francis L. Miller. He was wounded on July 1st and Major George Harney took command.

The regiment was one of the first Union infantry regiments on the field, taking an advanced position north of the Chambersburg Pike. Lt. Colonel Miller was ordered to fall back but was wounded before he could pass the orders on to his men. The regiment stood its ground, taking heavy casualties, before orders finally reached it alowing it to withdraw. Although the 147th lost three quarters of its men, its stand saved Hall’s 2n Maine Battery from destruction and probably saved the Union position south of Chambersburg Pike.

The 147th withdrew through town and was part of the defense of Culp’s Hill for the rest of the battle.

Killed and mortally wounded 76. Wounded 146, missing 79. Total loss 301. Number engaged 380.
