• The supposition made is that the most likely area of Tarleton's capture of the sloops and cannon would have been in the narrow 3-mile stretch between the Brickyard and Cainhoy (the upper limit of navigation of the Wando River per McCrady).

  On this 10th day of April A.D. 1833,
  ...
  The troops again rendezvoused at Hillsborough– They were marched under the command of Col. Hugh Tinnon to a point on Cooper river in sight of Charleston South Carolina. When they arrived at the above point the engagement had commenced at Charleston. This declarant together with about fifty others were under Captain Adam Sanders sent up the river in Boats for the purpose of conveying all the vessels they could which lay up the river down to Charlestown– About thirty of the fifty having taken some vessels down were enabled to reach town. But this declarant together with the balance, on their return, reached what was called the old Brickyard on the river [sic: probably near Mount Pleasant SC on a branch of the Cooper River now called the Wando River] we were compelled to leave our boats and make our escape into the woods on the East side of the river. We went then our Captain being with us to Santee river which we crossed at Duprees & Lippees ferry, as he understood one of the above individuals owning the boat & landing on one side & the other the oposite side of the river.

  Monday, 17th. Crossed Bono Ferry and passed on to Miller's Bridge, over a branch of Wando river, where we took up our ground about nine o'clock in the evening. This day passed St. Thomas' church, where we met the Thirty-third regiment.
  Tuesday, 18th. Began to fortify at the Bridge, and make a block house in order to keep post here with a few men.
  Wednesday, 19th. Maj. Ferguson, with fifty of the American Volunteers, and part of the North Carolinians, moved on to join the. Thirty-third and Sixty-fourth regiments, and the British Legion, which had gone forward to attack a Rebel post at Lempriere's Point. The British were coming back; they had marched up to the fort, but found it so strong that it was imprudent to storm it with so few men.
  Thursday, 20th. Remained at Miller's Bridge, finishing the block house. Col. Tarleton surprised and took nine sloops with goods, stores, etc., and twenty pieces of cannon.

  JR Note: The schooners were captured by Lt.Col. Tarleton, a dragoon commander. It is probable that they were captured near the northern limits of navigation, near shore, where the river was most narrow.
