Benedict was the site of Camp Stanton, constructed in October 1863 for the Maryland 7th Regiment.[9] Camp Stanton was also the location where the Maryland 19th Regiment of the United States Colored Troops was formed on December 19, 1863, with freed slaves who were purchased for their freedom by the United States Government to serve as soldiers.[10] This unit distinguished itself at the Battle of the Wilderness.[11] Some of its members included the Rev. William Saunders Crowdy and his brother Daniel, of a plantation in St. Mary's County.[citation needed]
A school was established on the site to educate the black soldiers, most of whom had received no education when they were slaves. The school was run by Samuel C. Armstrong.[12]
