Regimental History
Two Hundred and Tenth Infantry. - Cols., William Sergeant, 
Edward L. Witman; Lieut.-Col., Edward L. Witman; Majs., Henry 
E. Munson, James H. Graves, Sol. B. Bowerman. The 210th, from 
the counties of Dauphin, Columbia, Schuylkill, Potter, Mifflin, 
Bradford, Franklin and Center, rendezvoused at Camp Curtin, 
Harrisburg, and was mustered into the U. S. service from Aug. 
25 to Sept. 24, 1864, for one year. Col. Sergeant was formerly 
a captain in the 12th U. S. infantry, Lieut.-Col. Witman was a 
captain in the 46th Pa., and a large proportion of both offi-
cers and men had been in the service before. As soon as it was 
organized it left for the front and joined the army of the Po-
tomac before Petersburg, where it was assigned to the 3d bri-
gade, 2nd division, 5th corps. It was active for the first 
time at Hatcher's run in October, meeting with slight loss. It 
shared in the Weldon railroad expedition in December, suffering
much from the intense cold and exposure, which caused many to 
sicken and die. It behaved with great gallantry in the engage-
ment at Dabney's mill, in Feb., 1865, where its losses were 
considerable. On the opening of the spring campaign it was 
heavily engaged from March 29 to April 1, at the Quaker road, 
Gravelly run, the Boydton road and Five Forks, its loss being 
35 killed, 115 wounded and 150 missing. Col. Sergeant was mor-
tally wounded at Five Forks as were Adjt. Schlesinger and Capt.
Hughes. It followed the enemy during his retreat from Peters-
burg and was at the front when Lee's final surrender took 
place. It then returned to the vicinity of Washington, par-
ticipated in the grand review, and was mustered out at Alexan-
dria on May 30, 1865 when the recruits were transferred to the 
51st Pa., with which organization they served until their final 
muster out on July 28, 1865.
