Sixty-seventh Infantry. - Cols., Otto Burstenbinder, Alvin C. Voris; Lieut.-Cols., John R. Bond, Henry S. Commager, Lewis Cass Hunt, Henry R. West; Majs., Edwin S. Platt, Lewis Butler, Thomas J. Platt. This regiment was organized in the state at large, from Oct., 1861, to Jan., 1862, to serve for three years, and left Columbus for the field, Jan. 19, 1862, going into western Virginia. It was the first to engage the enemy at Winchester on March 23, and lost in that action 15 killed and 32 wounded. At Harrison's landing it campaigned with the Army of the Potomac till the evacuation of the Peninsula, when it went to Suffolk, Va., with only 300 men for duty out of the 850 which composed the regiment at the organization. Being then transferred to the Carolinas, for seven months it heroically endured all the hardships, privations, and dangers of the siege of Charleston, taking part in the attack on Fort Wagner and sustaining a heavy loss. The regiment re-enlisted and returned to Ohio on furlough, then took the field again in Virginia, and
May 10, 1864, will always be remembered as a sad but glorious day for it, when it lost 76 officers and men killed and wounded in the battle of Chester Station. Ten days later at Bermuda Hundred it participated in a charge and lost 69 officers and men killed and wounded. On Aug. 16, four companies charged the rifle-pits of the enemy at Deep Bottom and at the first volley lost a third of their men; but before the Confederates could reload the rifle-pits were in possession of the Buckeye boys. During the spring, summer and fall of 1864 the regiment confronted the enemy at all times within range of their guns; and it is said, by officers competent to judge, that in that time it was under fire 200 times. Out of over 600 muskets taken to the front in the spring three-fifths were laid aside during the year on account of casualties. It was in the siege of Petersburg, witnessed the close at Appomattox, and was mustered out Dec. 7, 1865.
