In 1780, the Maryland line was sent to the Carolinas, where they suffered horrendous losses at the battle of Camden (August 16). The remnants of the Maryland regiments were organized into two regiments. The reorganized 1st Maryland fought with great distinction at Cowpens (January 17, 1781), Guilford Courthouse (March 15, 1781), and Eutaw Springs (September 8, 1781). On each of these occasions the regiment launched a critical bayonet charge that broke well-trained British regulars. The regiment was also heavily engaged at Hobkirk's Hill (April 25, 1781) and the siege of Ninety-Six (May 22-June 19, 1781).
The Maryland Regiment of 1776 wore hunting shirts (in battle). Beginning in 1777, and continuing until the end of the war, the regiment wore blue coats with red facings. Below: An assortment of blue-coated Continentals by several manufacturers that can be used to represent the 1st Maryland or its sister regiments.
