WW2 British RAF J3/J4 Escape Map 26″ X 20 1/2″

The World War II British RAF J3/J4 Escape Map, measuring 26 inches by 20 1/2 inches, is a silk map produced for Royal Air Force airmen during the Second World War. These escape maps were developed to assist downed pilots and aircrew in evading capture and navigating occupied territories. The J3/J4 designation refers to specific map sheets featuring regions of strategic importance for British operations, typically covering parts of Germany and the surrounding European countries. Printed on lightweight, durable silk, the map could be easily concealed in clothing or carried without generating noise, making it suitable for covert use. The map details key topographical features, transportation routes, and important landmarks, providing practical information for escape and evasion scenarios. Issued as part of standard survival equipment, this type of escape map represents the ingenuity and resourcefulness employed in wartime survival strategies by the Allied forces.
