The Battle of Teruel was fought in and around the city of Teruel during the Spanish Civil War. The combatants fought the battle between December 1937 and February 1938, during the worst Spanish winter in twenty years. The battle was one of the bloodier actions of the war with the city changing hands several times, first falling to the Republicans and eventually being re-taken by the Nationalists. In the course of the fighting, Teruel was subjected to heavy artillery and aerial bombardment. The two sides suffered over 140,000 casualties between them in the two-month battle.
