Radcliff's Armada is an informal name given to a combined fleet of English and Dutch ships under the command of William Radcliff of Atlantis. The Armada was created with express purpose of destroying the Avalon pirates that preyed upon the ships that passed through the Hesperian Gulf, the most notorious of those pirates being Radcliff's distant cousin, Red Rodney Radcliffe. Radcliff secured the aid of another distant cousin, Marcus Radcliffe, who willingly provided some sixty Atlantean woodsmen as marines.
