The Battle of Harz took place in 1472 between the forces of the Order of Reason and the army of Tezghul the Insane. While many had challenged Tezghul's reign of terror, including the First Cabal, none had been able to stop him from slowly cutting a swath through Central Europe, from Lithuania to Germany. The Iron Hounds managed to slow but not stop his progress towards Berlin in early 1472.
