The Battle of Authion was a military engagement that took place towards the end of World War II, shortly before the defeat of Nazi Germany in 1945. Units of the French Army were sent to the French Alps to clear an important route from central France to Italy. A critical choke point was the 2,080 metre (6,820 feet) high Authion massif, held by determined but weakened German and Italian forces.
Field Marshal Harold Alexander authorised the assault on Authion on 10 April 1945.
