During World War II, Foggia was heavily bombed by the Allied air forces for its important airfields and marshalling yards. After the armistice of Cassibile on 8 September 1943, the town was briefly occupied by German troops in Operation Achse. There was some fighting there during the Allied invasion of Italy. In response to the Allied advance towards them, the German troops occupying Foggia abandoned the city on the 27th of September. By the 1st of October British troops had successfully occupied the city. In order to clear the Germans from the hills north and west of the Fogia plain and to reach the Vinchiaturo-Termoli road near the Biferno River, Britain's General Montgomery sent his British XIII Corps beyond Foggia on a two division drive, the 78th Division (sometimes known as "the Battle Axe division") moved on the coastal road to Termoli and the 1st Canadian Division struck inland through the mountains. British V Corps followed, protecting the west flank and the rear. The German 1st parachute division had largely withdrawn to the Biferno River near Termoli and dug in. Based out of Foggia, the British launched Operation Devon and succeeded in dislodging the Nazi German forces from Termoli.
