The RAF raid on La Caine (1944)was an attack on 10 June 1944 by aircraft of theRoyal Air Forceagainst the headquarters ofPanzergruppe WestduringOperation Overlordthe Allied invasion of France, which led the GermanPanzer divisionsin France and Belgium. The headquarters had recently taken over the château atLa Caine,about 12 mi (19 km) to the south-west of the city ofCaen,north ofThury-Harcourt.

Squadrons ofNorth American B-25 Mitchellmedium bombers andHawker Typhoonfighter bombers of theRAF Second Tactical Air Forceattacked the château and its grounds with bombs and air-to-ground rockets. Eighteen staff officers were killed in the attack and the commander,General der PanzertruppenLeo Geyr von Schweppenburgwas wounded.

A German armoured counter-offensive byPanzergruppe Westagainst the Allied beachhead was postponed and then cancelled after the destruction of the headquarters. Command ofPanzer divisionsin the area was transferred to theI SS Panzer Corpsheadquarters; the remnants of thePanzergruppe WestHQ was withdrawn to Paris and did not return to action until 28 June.

Background

[edit]

Panzergruppe West

[edit]

Generalfeldmarschall(Field Marshal)Gerd von Rundstedt,Oberbefehlshaber West(OB Westthe commander of German forces in western Europe) establishedPanzergruppe West,(commanded byGeneral der PanzertruppeLeo Geyr von Schweppenburg from 19 November 1943 to 4 July 1944) as a headquarters for the administration and training of the seven Panzer divisions based in northern France and Belgium. The organisation was also to command the Panzer divisions as a strategic reserve during the anticipated Allied invasion from Britain. On 9 June 1944, three days after the beginning ofOperation Overlord,the invasion of France by the Western Allies,GeneralfeldmarschallErwin Rommel,commander ofHeeresgruppe B(Army Group B) with responsibility for the defence of northern France, drove to the HQ ofPanzergruppe Westand gave orders for a counter-offensive against the Allied landings in Normandy.[2][b]

Allied monitoring of German communications

[edit]

TheGovernment Code and Cypher School(GC&CS) code-breaking organisation atBletchley Parkread German radio signals encrypted by theEnigmacypher machine and was part of the system of wireless listening posts,traffic analysisand direction finding used against Germany during the war.[4]Ultradecrypts on 11 and 18 March 1944 established the existence ofPanzergruppe Westand that its headquarters was in Paris.[5]A big increase in wireless traffic fromPanzergruppe Westwas detected by the British Monitoring Section on 8 June 1944, when the17th SS Panzergrenadier Divisioncame under the command of thePanzergruppe.The site of the source was identified byHigh-frequency direction finding(huff-duff) as the château in thecommuneof La Caine, about 12 mi (19 km) to the south-west of the city of Caen. The information was forwarded toSupreme Headquarters Allied Expeditionary Force(SHAEF) and other headquarters in Normandy.[6][c]Panzergruppe Westhad taken up residence at the château and left its vehicles in the orchard with no other camouflage.[2][d] The presence of four large wireless trucks, office caravans and tents was confirmed by reconnaissance aircraft.[9]

Prelude

[edit]

2nd TAF

[edit]

Early on 10 June, the RAF Second Tactical Air Force (2nd TAF) was ordered immediately to attack the château with every available aircraft. Four squadrons ofHawker Typhoonfighter-bombers were ordered to readiness; three of124 WingatRAF Hurnin Dorset (181 Squadron,182 Squadron,247 Squadron) and one of121 WingatRAF Holmsley South,Hampshire (245 Squadron).139 WingatRAF Dunsfold,comprising98 Squadron,180 Squadronand320 (Netherlands) Squadronwith226 Squadronof137 WingatRAF Hartford BridgeflyingNorth American B-25 Mitchellmedium bombers were alerted. A maximum effort consisted of ten Typhoons per squadron and eighteen Mitchells from each medium bomber squadron. The Typhoons were loaded with eight 60-lbRP-3rockets each and the Mitchells were to carry their maximum bomb loads of eight 500 lb (230 kg) bombs; four squadrons of Spitfires were to escort the bombers.[10]The rocket-firing Typhoons were to attack at low altitude and the Mitchells to bomb at medium altitude.[2]

Preparations

[edit]
The Typhoon could carry eight 3-inch RP rockets, seen being loaded, with its four 20 mm cannon

The morning of 10 June was overcast and cloudy; the10:30 a.m.briefing for a raid planned at2:00 p.m.was postponed until the cloud cover diminished.[e]Wing Commander Lynn, the Wing Commander (Flying), was to lead the Mitchells with 180 Squadron flying at the head of the formation. The weather was still not ideal and the first aircraft of each bomber squadron would haveGee-Hnavigation equipment, as a precaution against cloud over the target.[11]While waiting on the weather, the Typhoons of 124 Wing flew two raids on gun emplacements near Caen.[12]

The eighteen Mitchells of 180 Squadron took off in threeflightsof six at8:00 p.m.followed by seventeen Mitchells of 320 (Netherlands) Squadron (Commander H. V. B. Burgerhout).[12]At8:10 p.m.sixteen more bombers from 98 Squadron (Squadron Leader Eager) took off, the three squadrons circling while gaining height and getting into formation, then setting course for France at8:20 p.m.OverSelsey Billeighteen more Mitchells of 226 Squadron (Wing Commander A. D. Mitchell) joined the formation.[12]

The 33Supermarine Spitfire Mk VsofAir Defence of Great Britainfor close escort and the high and low cover of threeSpitfire Mk IXsquadrons from84 Group2nd TAF arrived soon afterwards.[12][f]A Mitchell from 226 Squadron and two from 180 Squadron turned back with mechanical problems before the attack.. The spare aircraft from two of the four Typhoon squadrons had joined in, giving 42 Typhoons, eight of which operated as fighters without rockets. The Typhoons were to attack in two waves, thirty minutes apart, the first wave to attack the motor transport around the château, synchronised with the bombing by the Mitchells and the second wave to attack anything left.[12]

Attack

In the evening of 10 June, GeneralSigismund-Helmut von Dawans,the chief of staff ofPanzergruppe Westand 18 staff officers were at dinner in Château La Caine when air raid sirens went off. The officers hurried outside to see and watched the Typhoons through binoculars, not aware that they were the target until the last minute; Schweppenburg arrived by car just before the attack. The 17 Typhoons of 181 and 247 squadrons fired 136 rockets from 2,000 ft (610 m). At 12,000 ft (3,700 m) the Mitchells of 139 Wing moved intoVic formationwith 226 Squadron at the base of the V, the squadrons remaining in the flights of six.[12]

At9:15 p.m.the bombers released552five-hundred pound bombs. The bombs on one Mitchell "hung up" and were not released. The bombs landed with great accuracy on the château and the grounds, killing Dawans, 17 of the 18 staff officers, wounding Schweppenburg and another officer. Four of the Typhoons not carrying rocketsstrafedthe village ofMontignynearby. After bombing, the Mitchells turned north-west, receiving anti-aircraft fire from the vicinity of Caen. The second wave of rocket-armed Typhoons arrived to find the château and thePanzergruppe Westvehicles already destroyed; the Typhoons fired their rockets at anything left standing. The Mitchells landed by10:25 p.m.and preparations began for a night operation.[12]

Aftermath

[edit]

As the Allied crews were debriefed, they claimed a big success; most bomber crews reporting that they had hit the target; anti-aircraft fire had been sparse and no German fighters had intervened, the Germans appeared to have been surprised.[12]The attack destroyed the only German army organisation in the western theatre capable of handling a large number of mobile divisions; the survivors ofPanzergruppe Westwere withdrawn to Paris and were not ready to resume operations until 28 June.[13]German command of the sector was temporarily given toSS-ObergruppenführerSepp Dietrichand theI SS Panzer Corps.In the 2009 edition of a history of the use of Ultra information, Ralph Bennett wrote that an armoured counter-attack against the Allied beachhead planned for 10 June, was postponed for 24 hours and then cancelled. Bletchley Park decrypted German signals thatPanzergruppe Westhad been destroyed and would have to be withdrawn to Paris to be reconstituted. The appointment of new staff commanded by GeneralHeinrich Eberbach,delayed the plans for the German armoured counter-offensive by three weeks when it was overtaken by events.[12]

La Cambe German war cemetery

The destruction thePanzergruppeHQ contributed to the loss of the initiative by the Germans. No German suspicions were aroused about Allied code breaking, because a reconnaissance aircraft had been seen before the raid. The decrypts revealing the whereabouts ofPanzergruppe Westwere the first of a series which exposed the positions of tactically valuable targets, including fuel and ammunition dumps, which were attacked to exacerbate German shortages, also being revealed by Ultra decrypts.[14]Eighteen staff officers ofPanzergruppe Westwere known to have been killed in the raid, including the chief of staff, Dawans, interred inLa Cambe German war cemetery;Schweppenburg was wounded. The château was not badly damaged but the nearby orchard, in which the HQ vehicles were parked, was thoroughly bombed and communications equipment was destroyed.[14]
