Flak enters in action as of the first minutes. The group of parachutists charged to release the passage towards the sea is released too much far from its drop zone. Two other parachutings are successful. Some gusts, a grenade, the six guards of the radar are very quickly killed. The Germans react quickly: hardly the dismounted radar, a Mg spits its grapeshot. Men collapse. But the objective is in the hands of Cox. After having destroyed the radars, the two groups start to evacuate in good order, direction the beach. This one has been under control of the third group only for a few minutes. In the course of road, this group with cross a German patrol: «Hallo!». German take them for friends. It should be believed that the paras can be relaxed at any time! A German soldier is mistaken and follows our English who gets rid some with the knife.
The cleaned beach, engineer Cox, major Frost and the remainder of the commando embark in the fast patrol boats of Royal Navy and regain their home port under the shooting of the médusés Germans.

It is a total success. The radar is with the hands of the English engineers. The operation made only two did not die, six wounded and six disappeared. Biting is a model for all the actions commandos. It will especially contribute to dig the advance allied in technology radar. In the current the 1943 first lures - the system «Windows» - are developed and used. They are fine aluminium strips which, released in masses in the airs, scramble the echoes radar. The radar is then plugged because it cannot detect the planes drowned in a metal mass.
