Most of the new Pennsylvania regiments were organized and trained at sprawling Camp Curtin near Harrisburg, as well as thousands of soldiers from other states. Other significant training sites were near Pittsburgh, Easton, Philadelphia and West Chester. Over 100 soldiers from Pennsylvania units would win the Medal of Honor for their actions during the conflict. Pennsylvania ranked first in the number of black soldiers (8,612) mustered into the Union Army, forming eleven regiments of U.S. Colored Troops. Most of these trained at Camp William Penn, established in 1863 north of Philadelphia, the only camp used to train Colored Troops exclusively. The 47th Pennsylvania Infantry also became an integrated regiment in October 1862 when several formerly enslaved Black men enlisted with the regiment while it was stationed in South Carolina, and was integrated further with the enlistment of additional formerly enslaved Black men in 1864 while the regiment was engaged in the Union's Red River Campaign across Louisiana.
