notes.--Recruited in July and August, 1865, from the counties of Saratoga, Montgomery, Fulton and Hamilton. Leaving the rendezvous at Fonda on the 29th of August, it arrived two days later at Sandy Hook, Md., where arms and equipments were furnished. Two weeks afterwards the entire regiment was captured at the surrender of Harper's Ferry, and after being paroled was ordered to Chicago to await exchange. During 1863, the regiment was stationed at Hilton Head and Beaufort, S. C., and thence, on February 5, 1864, sailed for Florida. At the battle of Olustee, Fla, the regiment made a gallant fight, losing over 300 in killed, wounded or missing. Leaving Jacksonville, Fla., on the 15th of April, 1864, the One Hundred and Fifteenth sailed with the Tenth Corps for Virginia, where it joined General Butler's Army of the James and was assigned to Barton's (2d) Brigade, Turner's (2d) Division, Tenth Corps. In the actions around Drewry's Bluff and Bermuda Hundred, May 6-16, 1864, it lost 6 killed, 87 wounded, and 7 missing; total, 100. While at Cold Harbor the brigade was attached temporarily to the Eighteenth Corps, but on its return to the James it rejoined the Tenth Corps and went into position before Petersburg. Recrossing the James, the regiment was engaged at Deep Bottom, where it lost 5 killed, 44 wounded, and 24 missing; total, 73. At the battle of Chaffin's Farm, the regiment was in the fight at Fort Gilmer, where it lost half of its number present in action; on October 27, 1864, it joined in the advance on Richmond on the Darbytown Road, in which affair the One Hundred and Fifteenth sustained considerable loss from a volley fired into them, through mistake, by the Ninth Maine. In December, 1864, the Tenth Corps was discontinued, and the regiment was transferred to Ames's (2d) Division of the newly-formed Twenty-fourth Corps. At Fort Fisher the regiment fought in Bell's (3d) Brigade, Ames's Division, many of the lives lost there occurring at the explosion of the magazine the day after the Fort was taken. Mustered out June I 7, 1865.
