On 27 February, in ideal tide and weather conditions, the raid was commanded by Major John D. Frost. A group of forty men would attack machine-guns on the cliffs overlooking the evacuation beach and then advance to Bruneval village. Another fifty-five men in an assault group would attack the radar station and forty men would set up a blocking position to prevent German reinforcements reaching the radar site. The parachute drop was mostly successful with half of the first group missing the drop zone (DZ) by . After capturing the radar and other installations, the assault group dismantled the equipment then withdrew towards the beach. They were intercepted en route by the cliff machine guns which had not yet been cleared and suffered some casualties. When the delayed first group arrived, they managed to neutralize the enemy machine guns and by 02:15 the company had mustered on the beach to wait for the navy. Despite some initial problems caused by a lack of experience in combined operations, the troops were successfully evacuated with losses of three men killed and seven wounded.
