Boatswain (The Curse of the Black Spot)

The boatswain was a pirate on board the Fancy in the 17th century.

He disagreed with Captain Avery's decision on how to protect themselves from the Siren. He and Mulligan decided to leave the ship until Toby cut his hand, giving him the black spot. He was imprisioned in the armoury by his captain and then taken by the Siren to her ship after she came through the reflection of his sword (REF: The Brilliant Book 2012), and later joined the rest of the crew when they took the ship for themselves. (DW: The Curse of the Black Spot)

Some time later, the Doctor recruited Avery to help him with an attack on the asteroid of Demon's Run to rescue Amy Pond. The boatswain and the crew boarded the ship of Madame Kovarian during the attack and subdued its crew, preventing her escape. (DW: A Good Man Goes to War)
