 There are two "Thatch" islands in the BVI (Great Thatch and Little Thatch) and almost directly opposite Road Harbour is the island known as 'Deadchest,' where Blackbeard allegedly marooned a number of his men giving the island its name.These men were supposed to have tried to swim to the adjacent Peter Island but drowned, hence the name 'Dead Man's Bay' on Peter Island.The reality is that there is no documentary evidence to support any of this and academically speaking, there is no proof to show that Blackbeard ever sailed through the Virgin Islands.
