The Battle of Mon Cala, also known as the Battle of Mon Calamari or the Attack on Mon Cala, was fought during the Clone Wars on the aquatic world of Mon Cala. The battle was a result of a schism between the Mon Calamari and Quarren species who lived on the planet, as the Quarrens rebelled against the Mon Calamari with the support of the Confederacy of Independent Systems. The Grand Army of the Republic, Jedi Order, and the Gungan Grand Army came to the defense of the Mon Calamari to fight the invading Separatist Droid Army. The Mon Calamari and the Quarren reunified by the battle’s end, and the Separatists were repelled.
