Overview
The 154th Pennsylvania Infantry (Nine Months’ Service) was an infantry regiment organized in Pennsylvania for Union service during the American Civil War. The regiment was formed in late 1862, with its companies mustered in at Philadelphia between November 1, 1862, and January 21, 1863. The unit served exclusively in the Department of the East, performing provost (military police) duties in Philadelphia. The regiment was never fully organized, as only three companies—A, B, and C—remained together, while the other companies were detailed for special duty before the field officers were commissioned.
This regiment served a nine-month term and did not participate in field campaigns or major battles, focusing instead on maintaining order and security within Philadelphia.
Organization & Service
The 154th Pennsylvania Infantry (Nine Months’ Service) began organizing in December 1862. Although enough companies were initially raised to form a full regiment, seven companies were detached for special assignments before the regiment’s field officers could be commissioned. As a result, only Companies A, B, and C remained as the 154th Pennsylvania Infantry.
These three companies were mustered into United States service at Philadelphia between November 1, 1862, and January 21, 1863, for a nine-month enlistment. The regiment was assigned to provost duty in Philadelphia, responsible for maintaining order, enforcing military regulations, and supporting local authorities. Companies A and B were mustered out at Philadelphia on September 29, 1863, and Company C followed on October 21, 1863. The regiment did not serve in the field or participate in combat operations.
