The New York Volunteers were one of several regiments of Provincials (Loyalists that were essentially trained and equipped in the manner of British regulars) that served in the Southern campaign of the American Revolution.
Loyalist refugees in New York began fleeing in 1775 to the British authorities, and these were formed in early 1776 at Halifax into two companies of Volunteers. The companies were first deployed at the battles of Long Island (1776) and White Plains (1776). The Volunteers were subsequently expanded and in 1779 were placed on the American Establishment and designated the 3rd American Regiment (although they continued to be referred to as the New York Volunteers). The Volunteers participated in the storming of Fort Montgomery, New York (1777), the capture of Savannah, Georgia (1778), the siege of Savannah (1779), and the siege of Charleston, South Carolina (1780). Following the capture of the American army at Charleston, the regiment was assigned to garrison the post at Rocky Mount, South Carolina, one of a string of posts across the northern portion of the state. The regiment was engaged at the battle of Rocky Mount (1780), and, after that post was abandoned, Hobkirk's Hill (1781), and Eutaw Springs (1781). Detachments were also present at Williamson's Plantation (1780), Camden (1780), and King's Mountain (1780).
The regiment appears to have worn red coats, faced blue, while in South Carolina.
