Under command of Col. Maulsby, the regiment formed part of 2nd Brigade (Brig. Gen. Henry H. Lockwood), 1st Division (Brig. Gen. Alpheus S. Williams), XII Corps (Maj. Gen. Henry W. Slocum) at the Battle of Gettysburg. The regiment mustered 674 all ranks, making it the largest regiment in the Army of the Potomac. The regiment reached Gettysburg during the afternoon of July 1, but was not engaged.
On the morning of July 2, the regiment constructed breastworks south of Culp's Hill at McAlister's Woods. The entire division was withdrawn later in the day and sent south to support a section of the Union line under attack by Longstreet's Corps. Returning to Culp's Hill that evening, the regiment discovered that its breastworks had been captured by Confederates of Maj. Gen. Edward "Allegheny" Johnson's division.
On July 3, the regiment fought to hold ground against renewed attacks by Johnson's division. Bloody fighting continued until around 11:00 a.m. when Johnson finally broke off his attack. XII Corps commander Brig. Gen. Alpheus Williams wrote: "The wonder is that the rebels persisted so long in an attempt that the first half hour must have told them was useless."
The regiment mustered 674 all ranks at the beginning of the battle. It lost 104 killed, wounded, captured and missing.
