Ill Met by Moonlight - Michael Powell, Emeric Pressburger

Based on the true story of how, during World War II, a gang of desparadoes (British officers enlisted for "hostilities only" and local partisans) went to the occupied island of Crete and kidnapped a German General from under the nose of his army. That was the easy bit !!! They then had to get him back to Cairo, dodging an intense air and land search.
