Rhett was a Colonel in the Provincial Militia and Vice-Admiral in the Colonial Navy. He is best known for his successful capture of the notorious pirate Stede Bonnet in 1718. He also held appointments as Surveyor and Comptroller General for His Majesty's Customs and was Lieutenant-General and Constructor of Fortifications.
