On the 8th June General Geyr von Schweppenburg, Commander of Panzer Group West arrived at his battle headquarters and received his orders. Ultra picked up two of the signals he received and the second one included a pinpoint location of Panzer Group West's HQ. On the 10th June a bombing attack was launched against the HQ and so many of Geyr's staff were killed or wounded that Panzer Group West was not operational again for a fortnight. The raid was carried out by aircraft of the Second Tactical Air Force. The raid consisted of 40 rocket-armed Typhoons which attacked in three waves from low altitude and by 61 B-25 Mitchell bombers which dropped 500lb bombs from 12,000 ft. Some four hundred bombs were dropped but only around a hundred found the target. As a result of the raid a counter attack by the Germans planned for that day was halted in its tracks. It was first delayed for 24hrs then 1 SS-Panzer Corps was asigned to direct it, but it was eventually cancelled altogether. Eighteen members of the HQ staff were known to have died in the raid, including the Chief-of-Staff Generalmajor Sigismund-Helmut von Dawans the most senior officer to be killed in the raid. The group's commander, Generalleutnant Leo Geyr von Schweppenburg, was wounded in the raid. Although the Chateau used as the HQ was not badly damaged, the nearby orchard in which the HQ's vehicles were parked, was thoroughly bombed. and communications equipment was also destroyed. Rommels chief of intelligence has been quoted as saying that they would have been better off without wireless even though at the time the Germans did not suspect that their communications had been compromised. Indeed a aircraft from the RAF had been seen reconnoitring the target prior to the raid and the Germans believed this aircraft gave the HQ's location away. It was about this time that the initiative swung decisively in favour of the Allies and Ultra may claim (and rightly so in my opinion) a share in the credit for this happening. By providing the infomation to allow the Allies to effectively strike and wipe out Panzergruppe West's HQ. Ultra virtually destroyed the nerve centre of the armoured striking force and impeded Rommel's plan for a mass blow to split the Allies bridgehead in two and drive the Allies back into the Channel. The Chateau at La Caine today once used as the the German HQ Generalmajor Ritter und Elder von Dawans, Chief of Staff of Panzer Group West. The German War Cemetery at La Cambre. The final resting place of Von Dawans. Initially all the casualties were buried in a bomb crater near the chateau. In 1957 the Volksfund Deutsche Kreigsgraberfursorge moved the remains from Le Mesnil-Auzouf to La Cambre. Their remains can be found at Block 30, Row 10, Graves 383-400.
