Eventually the unit was named the Royal North Carolina Regiment, and had eventually had as many as men. Hamilton and his regiment saw action at the Siege of Savannah, as well as the battles of Briar Creek, Kettle Creek (Hamilton may have meant only the battle of Carr's fort that preceded Kettle Creek), Stono Ferry, Monck's Corner, Hanging Rock, Camden, and the Guilford Courthouse. Hamilton lost a pair of pistols to Colonel Andrew Pickens at the battle at Carr's fort on February 10, 1779. Today those pistols are on display at the Museum of Art and History in Pickens, South Carolina.
