An answer to that pressing question — what DO pirates have for breakfast?

Captain Thomas Pound.

On August 8th, 1689, this pirate, with five men and a boy, sailed out of Boston Harbour as passengers in a small vessel. When off Lovell’s Island, five other armed men joined them. Pound now seized the craft and took command, and declared his intention of going on a piratical cruise. The first vessel they met with they decided to take. It was a fishing boat. Pound ran his craft alongside, but at the last moment his heart failed him, and he merely bought eight penn’o’th of mackerel from the surprised fishermen.
