Operation Biting, also known as the Bruneval Raid, was the code name given to a British Combined Operations raid on a German radar installation at Bruneval in northern France, which took place on the night of 27--28 February 1942 during World War II. A number of these installations were identified from Royal Air Force (RAF) aerial reconnaissance photographs during 1941, but their exact purpose and the nature of the equipment that they possessed was not known.
