Trask (The Highlanders)

Trask was Willie Mackay's partner in smuggling weapons from France to Scotland during the Jacobite Rebellion. He betrayed Mackay to the English and seized control of his ship, the Annabelle. Trask became part of Grey's slave-trading ring, and took prisoners on board for transporting to Caribbean plantations. With the Doctor's help, the prisoners rose up against Trask and threw him overboard. (DW: The Highlanders)
