The 3rd Maryland Regiment was an infantry regiment of the Continental Army during the American Revolutionary War. It served from 1776 to 1783, mostly in the Middle Atlantic Region of the conflict. Background The 3rd Maryland Regiment was organized on 27 March 1776 of eight companies from Anne Arundel, Prince George's, Talbot, Harford and Somerset counties of the colony of Maryland. The regiment was authorized on 16 September 1776 for service with the Continental Army and was assigned on 27 December 1776 to the main element. 1st Maryland Brigade On 22 May 1777 it was assigned to the 1st Maryland Brigade. The regiment was re-organized to nine companies on 12 May 1779. On 5 April 1780 the 1st Maryland Brigade was reassigned to the Southern Department. The regiment was relieved from the 1st Maryland Brigade on 1 January 1781. It was assigned to Gist's Brigade on 24 September 1781 in the main Continental Army. Three days later (27 September 1781) Gist's Brigade was reassigned to the Southern Department. On 4 January 1782 the regiment was reassigned from Gist's Brigade to the Maryland Brigade in the Southern Department. The regiment would see action during the Battle of Brandywine, Battle of Germantown, Battle of Monmouth, Battle of Camden, Battle of Guilford Court House, Battle of Eutaw Springs and the Battle of Yorktown. The regiment disbanded on 1 January 1783 at Charleston, South Carolina. Under Gist's command Gist became colonel in command of the 3rd Maryland on 10 December 1776. On 22 May 1777, George Washington assigned the regiment to the 1st Maryland Brigade together with the 1st Delaware Regiment, and the 1st, 5th, 7th Maryland Regiments. During the Battle of Brandywine on 11 September 1777, both the popular brigade commander William Smallwood and Gist were on detached duty recruiting the Maryland militia. This left the disliked Frenchman Philippe Hubert Preudhomme de Borre as the senior brigadier. The regiment was in John Sullivan's division on the right flank, guarding Brinton's Ford while other elements of the division guarded three upstream fords. Finding that the greater part of Sir William Howe's army had marched into the right rear of his division, Sullivan had to march cross country in an attempt to block the move. Finding his division in an awkward position, Sullivan rode off to confer with Adam Stephen and Lord Stirling and ordered De Borre to shift the division to the right. The
