notes.--Formerly the Sixty-fourth Militia, but reorganized as a volunteer command at Elmira in the autumn of 1861. The regiment arrived at Washington, December 11, 1861, and went into camp near the capitol. It commenced active service in Virginia, January 2, 1862, performing picket duty, with an occasional reconnoissance, until April 5, 1862, when it sailed for the Peninsula with General McClellan's Army. It served there in Richardson's Division — afterwards Hancock's — remaining in that division (1st Division, 2d A. C.) until the end of the war. The Sixty-fourth, under Colonel Bingham, distinguished itself at Chancellorsville, where, in company with four other regiments, it held successfully an advanced skirmish-line against the persistent attack of a large force of the enemy. This line was in charge of Colonel Nelson A. Miles of the Sixty-first New York, and the brilliancy of the affair became a matter of history. The regiment fought at Gettysburg in Caldwell's Division (same division), and lost there 98 out of the 20 officers and 185 men who marched with the colors on that field.
