During the Greece campaign, the German airborne forces would perform their last strategic parachute and glider performances of the war.[18] The Fallschirmjäger captured a critical bridge that crossed the canal in the Isthmus of Corinth so German forces could pursue Allied forces further in the Greek mainland.[19] The operation did not go smoothly due to heavy enemy ground fire.[19] Demolition charges were also accidentally detonated, due to carelessness, leading to damage to the bridge and heavy casualties.[19] One group of paratroopers was accidentally dropped into the sea where they all drowned.[19] The Fallschirmjäger did manage to capture British anti aircraft positions which forced the surrender of the local town.[19] 12,000 Commonwealth and Greek troops were also captured.[20] The Fallschirmjäger suffered 63 killed and 174 wounded.[19]
