Ninth Crusade

The Ninth Crusade, or referred as The Grand Army of the Reconquista is a complete Catholic army in the employ of the Vatican. They gather under the command of Archbishop Enrico Maxwell in order to partake in purging England of Millennium's forces.

Their mission was to aid Hellsing and Alucard in destroying Millennium; however, Maxwell, utterly drunk on power and fanaticism, turned on Hellsing and ordered the the Knights to attack and destroy everyone, soldiers and civilians alike, in an effort to kill all protestants in England and force a massive Catholic conversion. During their battle with Millennium however, they manage to cripple the Major's zeppelin severely with their gunships and inflict severe casualtes on the vampire army up to the point only 572 remained.

Despite being armed with weapons meant to be effective against unholy monsters as well as heavy gunship support, they were overrun and destroyed by Alucard's massive army of familiars. Thirty years into the future, their numbers still were low enough for them to seriously force them to wait for centuries before even considering the possibility of a Tenth Crusade.
