The 134th New York at Gettysburg
The 134th New York was commanded at the Battle of Gettysburg by Lieutenant Colonel Allan H. Jackson while Colonel Charles Coster was in command of the brigade. It brought 488 men to the field, losing 42 killed, 151 wounded and 59 missing.
When the 11th Corps reached Gettysburg on July 1, the regiment along with its 2nd Division was held in reserve on Cemetery Hill while the rest of the corps formed for battle north of town. When that battle line began to collapse in the afternoon the regiment and its brigade were marched through town and formed on the north side of Gettysburg to cover the retreat.
It turned into disaster. The 134th New York held the right flank of the brigade, and lost over half its strength in a few minutes when assaulted and overwhelmed by Confederates of Hoke’s and Hays’Brigades.
The survivors retreated through town and reformed on Cemetery Hill, which they defended during the attack on the evening of July 2nd and during the artillery barrage which preceded Pickett’s Charge.
Lieutenants Henry Palmer and Lucius Mead and 57 enlisted men were killed or mortally wounded, Captains Otis Guffin and William Mickle and 130 enlisted men were wounded, and Lieutenant John Kennedy and 57 enlisted men were captured. Lt. Colonel Jackson was captured during the retreat through town, but escaped and rejoined the regiment.
