15th Vermont Infantry

The 15th Regiment, Vermont Volunteer Infantry (or 15th VVI) was a nine months' infantry regiment in the Union Army during the American Civil War. It served in the eastern theater, predominantly in the Defenses of Washington, from October 1862 to August 1863. It was a member of the 2nd Vermont Brigade.

The 15th Vermont Infantry, a nine months regiment, raised as a result of President Lincoln's call on August 4, 1862, for additional troops due to the disastrous results of the Peninsula Campaign.

It was composed of volunteers from Caledonia, Orleans, Orange and Windsor counties, as follows:

Colonel Redfield Proctor, previously of the 3rd and 5th Vermont regiments, was selected to command the regiment. He would later serve as Governor of Vermont. William W. Grout, the regiment's lieutenant colonel, would later serve in the U.S. Congress.

The regiment went into camp at Brattleboro on October 8, 1862, occupying barracks just vacated the day before by the 12th Vermont Infantry, and was mustered into United States service on October 22. It left Vermont on October 23, and arrived in Washington, D.C. on October 26; the next day it joined the 14th Vermont Infantry and some Maine regiments in Camp Chase, in Arlington, Virginia, then returned to camp on East Capitol Hill, and on October 30 became part of the 2nd Vermont Brigade.
