In 1644, pirate Captain John Mucknell stole a brand new forty four gun ship called the John, and took to piracy with it on the high seas during the English Civil War. Under the flag of Charles I, Mucknell then inflicted terror upon merchant shipping around the Isles of Scilly and the western approaches that lasted for nearly 8 years. The author delves into this facinating pirate and what remains of his first ship on the sea bed at Scilly.
