What famous pirate captain had a wooden leg?

The obvious answer, I think, is the fictional Long John Silver in R. L. Stevenson's "Treasure Island" though he wasn't a captain:

"His left leg was cut off close by the hip, and under the left shoulder he carried a crutch, which he managed with wonderful dexterity, hopping about upon it like a bird. He was very tall and strong, with a face as big as a ham - plain and pale, but intelligent and smiling."

Obviously, if you are looking for a person who really lived this isn't the correct answer.

Hector Barbossa, the fictional pirate captain of the Black Pearl in the "Pirates of the Caribbean" movies, had a wooden leg.

Long John Silver had a crutch but not a wooden leg.

Captain Ahab, the captain in Melville's "Moby Dick", had false leg but it was made of whale bone.

François Leclerc (~1554), privateer
Cornelis Jol, (1597-1641), privateer and admiral of the Dutch West India Company

These should work since privateers were just authorized pirates.
