The Battle of Witches' Rock was a wizarding battle that occurred in January of 2011. The battle took place between Aurors from the Dinétah Auror Authority (including Henry Tsotsie, along with Alexandra Quick) and a horde of Dementors summoned from the Rock by John Manuelito following his duel with Quick. Quick had lured the werewolf pack toward Witches' Rock, however, and prevented Manuelito from performing his full ritual at the Rock's summit, lessening the damage of the Convention's full attack and focusing the fighting at the Battle of Witches' Rock.
