The Guns of Navarone

Based on Alistair MacLean's 1957 novel, this British-American epic war film tells the story of the Battle of Leros during the Dodecanese Campaign of World War II. With the Battle of Stalingrad turning the war against them in 1943, the Germans  attempt to bully neutral Turkey into joining the Axis powers; to this end they have trapped 2,000 British soldiers on Kiros, an island in the Aegean, with only one sea route for evacuation, a  route commanded by two gigantic German anti-ship batteries deployed in a massive cliffside bunker on the island of Navarone. A British team is sent to cross the occupied Greek territory and destroy the German gun emplacement that commands the route.
