Operation Biting
Encyclopedia : O : OP : OPE : Operation Biting
During World War II, Operation Biting (also known as the Bruneval Raid) was a Combined Operations raid to capture components of a German Würzburg radar set at Bruneval, France, on 27/28 February, 1942.
British scientists, led by R.V. Jones, needed to find out more about Würzburg radar so that they could come up with countermeasures in their ongoing battle of the beams with German scientists. Jones thought that the Germans might locate Würzburg radars at the same sites as Freya radar, so he requested aerial reconnaissance of known Freya sites. On 22 November 1941, a reconnaissance Spitfire took photographs of a Freya radar site in the grounds of a cliff top hotel at Bruneval, a village on the French coast near Le Havre, which contained unknown structures. On 5 December, a low-level reconnaissance flight by Tony Hill took very clear front and side pictures of the Würzburg radar with a person in the frame, which allowed the size of the radar dish (about 3 meters (10 feet) in diameter) to be assesed.
R.V. Jones judged that it was probably a Würzburg installation, so Combined Operations, which was under the command of Lord Louis Mountbatten, looked at the feasibility of a raid. A plan was drawn up to use a commando team to carry out a raid, recently trained as paratroopers and known as 1st Parachute Brigade. A RAF radar operator, Flight Sergeant C.W.H. Cox, would accompany them, and they would photograph the radar in detail and carry off whatever components they could.
On 27 February 1942, the raiding party of 120 men from C Company, 2nd Battalion, led by Major John Frost, was dropped on Bruneval from twelve Whitley bombers. The raid met considerable enemy resistance but they were able to photograph the installation, rip out some of the key electronics, and capture a Würzburg technician. As planned, they then retreated from the cliff tops down onto a beach where their naval evacuation was covered by No.12 Commando providing protection during the naval evacuation stage. It was later discovered that the Royal Navy flotilla had been playing 'cat-and-mouse' with a German force of a Destroyer and E-boats who passed within a mile of the landing. The British losses were two killed and four captured. Five Germans were killed and two taken prisoner, including the technician.
Back in Britain, examination of the Würzburg components showed that it only operated over a very narrow band and had no provisions for dealing with countermeasures. However, it was of a modular design that aided maintenance and made the hunting down faults simpler than on similar British models. This was confirmed during the interrogation of the captured German technician, who proved to be less well trained than his British counterparts.
The success of Operation Biting was splashed across the British press and went some way to improve the public's morale after a string of failures, including the armed forces' attempt to stop the German Channel Dash two weeks earlier. The success of the raid also highlighted to the British authorities how vulnerable British installations close to the sea were to enemy commando raids. This prompted the relocation of the TRE from Swanage to Malvern, where it has remained ever since.
In response to the Biting raid, the Germans fortified their radar sites. During the large but very costly Dieppe Raid, a subsidiary raid failed to capture Freya components because of the new fortifications. As is the tendency with the military in all countries, detailed plans were drawn up as to how fortification should be done. This helped with aerial reconnaissance, because the defences had a signature design which were much easier to spot from the air than the sites had been previously without the defences. Once found, the sites could be bombed.
