Sixty-third Infantry.—Cols., Richard C. Enright, John Burke, Henry Fowler, Richard C. Bentley, John H. Gleason, James D. Brady; Lieut.-Cols., Henry Fowler, Richard C. Bentley, John Stewart, John H. Gleason, James D. Brady, William H. Terwilliger; Majs., Thomas F. Lynch, Richard C. Bentley, Joseph O'Neil, Thomas Touhey, Miles McDonald, John H. Gleason, James D. Brady, William H.

The 63d, the 3d Irish regiment, composed mainly of recruits from New York city, but containing a number from Boston and some from Albany, was mustered into the service of the United States at New York city from Sept. to Dec., 1861, for three years. It left New York Nov. 28, 1861, for Washington and was assigned to the Irish brigade in Sumner's division, which became the 2nd brigade, 1st division, 2nd corps, Army of the Potomac. The regiment remained in the vicinity of Washington during the winter but was early in motion in the general advance to the Peninsula. Trench duty and picket duty occupied the troops during the siege of Yorktown but the regiment was in action at Williamsburg, Fair Oaks and during the Seven Days' battles. At Antietam the Irish brigade showed its mettle, the 63d losing 6 officers mortally wounded and 202 killed or wounded out of 341 engaged. The regiment then moved into Virginia and arrived at Falmouth in November. It went into the battle at Fredericksburg with 162 men, of whom 44 were reported killed, wounded or missing. After spending the winter in camp near Falmouth the 63d participated in the Chancellorsville campaign, and in June, 1863, was consolidated into two companies. This little force lost 23 at Gettysburg, fought at Auburn and Bristoe Station, shared in the Mine Run campaign, and established winter quarters near Brandy Station. In . Oct., 1863, a company of new recruits was added to the regiment, two more companies in April, 1864, and in June, 1864, one company, which with the reenlisted men continued it in service as a veteran organization. At the Wilderness 99 of the regiment fell, and 31 in the week following, among them Maj. Touhey. At Cold Harbor and in the first engagements before Petersburg the loss was severe. The regiment was active at Deep Bottom, Strawberry Plains, Reams' station, Hatcher's run, Fort Stedman, the final assault on April 2, 1865, and joined in the pursuit to Appomattox. It was mustered out at Alexandria on June 30, 1865, having lost 157 by death from wounds and 95 from other causes, out of a total enrollment of 1,411. The Irish brigade, as well as the individual regiments composing it, became noted for bravery on many a hard-fought field, and the 63d, which was one of the original regiments of the brigade, was one of New York's most gallant organizations.
