The Battle of Crucifix Hill was a World War II battle that took place on 8 October 1944, on Crucifix Hill (Haarberg) (Hill 239), next to the village of Haaren in Germany and was a part of the U.S. 1st Division's campaign to seize Aachen, Germany. The Battle of Aachen was part of the Drive to the Siegfried Line. The hill was named after a large crucifix mounted on the top of the hill. The objective of the battle was to gain control of the hill, which was laced with a maze of pillboxes and bunkers, so that the main objective of encircling Aachen could be completed.
