Question: Where is the castle that John Crabbe defended in 1318 against the English?

full_context: Document 1: William Snelgrave: William Snelgrave was an English sea captain, slave trader, and ivory trader on the West African coast. He was captured by pirate captains La Bouche, Thomas Cocklyn, and Howell Davis along the coast of West Africa in 1719. He was originally attacked by Cocklyn's quartermaster for failing to surrender. He was beaten and shot in the arm, but his men cried out "For God's sake, don't kill our captain, for we were never with a better man." Snelgrave was then spared. Snelgrave wrote about his captivity with the pirates. He described how Davis claimed that "their reasons for going a pirating were to revenge themselves on base merchants and cruel commanders of ships." This probably explains why Snelgrave was spared, despite the fact that he intended to fight the pirates.
Document 2: Carlisle Castle: Carlisle Castle is situated in Carlisle, in the English county of Cumbria, near the ruins of Hadrian's Wall. The castle is over 900 years old and has been the scene of many historical episodes in British history.

Today the castle is managed by English Heritage and is open to the public. The castle until recently was the administrative headquarters of the former King's Own Royal Border Regiment now county headquarters to the Duke of Lancaster's Regiment and a museum to the regiment is within the castle walls.

Document 9: Blackbeard: Edward Teach or Edward Thatch (c. 1680 22 November 1718), better known as Blackbeard, was a notorious English pirate who operated around the West Indies and the eastern coast of Britain's North American colonies. Although little is known about his early life, he was probably born in Bristol, England. Recent genealogical research indicates his family moved to Jamaica where Edward Thatch, Jr. is listed as being a mariner in the Royal Navy aboard HMS "Windsor" in 1706. He may have been a sailor on privateer ships during Queen Anne's War before settling on the Bahamian island of New Providence, a base for Captain Benjamin Hornigold, whose crew Teach joined sometime around 1716. Hornigold placed him in command of a sloop he had captured, and the two engaged in numerous acts of piracy. Their numbers were boosted by the addition to their fleet of two more ships, one of which was commanded by Stede Bonnet, but toward the end of 1717 Hornigold retired from piracy, taking two vessels with him.
