Birtwistle

Birtwistle was the coxswain aboard Edward Kenway's ship, the Jackdaw.

Upon the ship's return to Bristol in 1723, Edward planned to assassinate the Templars responsible for an attack on his family a decade earlier. Having learned that a troop of soldiers were on their way to Bristol, Edward met with Birtwistle in a tavern. There, he instructed the coxswain to bring the Jackdaw to the harbor, in preparation for their escape from Bristol.
