The Germans generally assumed that the Pas de Calais was the likeliest place for the invasion. The Allied deception plan was also intended to give the impression that diversionary attacks would be made in Normandy and southern Norway before the main attack on the Pas de Calais. It was implemented by creating imaginary army units and using various decoys, such as aircraft, tanks and landing craft. False information about the invasion was also passed to the Germans by the double agent known as 'Garbo'. These measures were very successful and discouraged the Germans from reinforcing their troops in Normandy even after D-Day. This document contains notes and photographs of dummy aircraft, one of which is shown here.
