Stay Behind Cave

Tracer
Stay Behind Cave or Operation Tracer to give it its proper name was one of the best kept secrets of WW2. In the event of Gibraltar being captured by German forces, six men would have been sealed into a secret chamber in which they would have been expected to survive and observe the activities of the Germans for a period of one year or more. #army #cave #Gibraltar #military #observation_post #Operation_Felix #Operation_Tracer #secret_chamber #Stay_Behind_Cave #tunnel #tunnels #WW2
