# Anderson Troop

Anderson Troop was an independent cavalry company that served in the Union Army during the American Civil War. It had an authorized strength of 110 officers and men, and served for 18 months at the headquarters of Generals Don Carlos Buell and William S. Rosecrans, commanders of the Department and Army of the Ohio and Cumberland. The unit was frequently referred to as "Anderson Troop, Pennsylvania Cavalry", and while occasionally identified as the 15th Pennsylvania Cavalry because its officers raised and organized that regiment, it was never a part.

## Service

The Anderson Troop was organized at Carlisle, Pennsylvania in October–November 1861 and mustered in on November 30, 1861 under the command of Captain William Jackson Palmer of Philadelphia, its organizer. The company was raised for headquarters and escort duty with Gen. Robert Anderson in Kentucky but instead became a unit of "elite scouts." Palmer, a Quaker, recruited a number of men of his faith to serve in the company, and all members were hand-picked after nomination by upstanding citizens of Pennsylvania. Among the requirements for enrollment was an oath to abstain from consumption of liquor for the duration.
In July 1862 Captain Palmer, 1st Lt. William Spencer, and 12 men were detailed to raise three additional companies of similar recruits to form a battalion to be known as the 1st Anderson Cavalry, with the Anderson Troop as its Company A. The recruiters, however, received sufficient applications to raise an entire regiment, which was authorized and became the 15th Pennsylvania Volunteer Cavalry. Palmer left the troop to become colonel of the 15th and Spencer the lieutenant colonel.
Although known as the "Anderson Cavalry," the regiment nonetheless did not incorporate the company into its ranks when it elected to remain independent under the command of its second lieutenant, Thomas Maple. 11 of its 17 officers and non-commissioned officers, with 21 of 90 privates, had joined the 15th, the majority of them commissioned as officers. With the 15th Pennsylvania Cavalry designated to become his headquarters cavalry, General William Rosecrans felt that the two units could not serve side-by-side without friction and offered the remaining 53 men of the Anderson Troop the opportunity to muster out of service, which was done on March 24, 1863. Maple continued in service as a major and assistant army quartermaster.
