A badly damaged M-10 tank destroyer had come to a halt by the side of the road from Saint-Denis to Lengronne. The crew inside played possum as the German column passed, then, as soon as the last half-track had gone by, they brought their three-inch gun to bear and began knocking them out, one by one, firing twenty-eight rounds altogether.
The main force at the crossroads had to pull back to higher ground, where infantry could protect the Shermans from German foot soldiers trying to stalk them with Panzerfaust launchers. The first vehicle in the German column, a Mark IV tank towing an 88 mm gun, advanced towards the defensive position and was destroyed by a tank shell. ‘Then the organized slaughter started,’ an officer reported. The mortar platoon began rapid fire down the line of the convoy, ‘a ratio of one white phosphorus to three high explosive’. The vehicles set ablaze by the white phosphorus lit up the scene, aiding the tank gunners and mortar crews, who dropped high-explosive rounds into the open backs of the German half-tracks. While their gunners continued to engage targets, tank commanders were having to fight off German infantry with the .50 machine gun mounted over their hatch.
One officer recorded that ‘as daylight broke, about 300 German infantrymen tried to advance through a swamp to the north of the Grimesnil road… the tanks went after them and killed nearly all. Close to 300 bodies were found in and around this swamp.’ Another 600 dead were found along the road which had been shelled — ‘a bloody mass of arms and legs and heads, [and] cremated corpses… at least three German women were found in various stages of decapitation’. One of them had been driving a major general’s staff car.‘The major general was identified by his uniform, but when battalion officers returned later they found that souvenir hunters had taken all his clothes.’[58]
The American graves registration service retrieved 1,150 German dead from the convoy of ninety-six vehicles. ‘The whole area was raw meat splattered on burned and ruined vehicles,’ observed one officer. Another report stated that ‘prisoners were coming in so fast that it became impossible to count them. Many stated that they had not eaten for two or three days.’ Meanwhile the 82nd Reconnaissance Battalion slipped south to seize bridges over the River Sienne.
Brigadier General Hickey’s combat command from the 3rd Armored Division, following the German retreat, found in Roncey that ‘German equipment, abandoned and broken, cluttered the road to such an extent that progress through the main street was impossible, and the task force had to go through the back streets to get out of the town’. A tank dozer had to be brought up to clear the main road. So many German soldiers were surrendering that they had to send them to the rear without a guard. When the 3rd Armored reached the area of Grimesnil and Saint-Denis-le-Gast, a medical officer noted in his diary ‘Carnage gruesome. Includes enemy dead smashed flat by our tanks.’
Generalmajor Rudolph-Christoff Freiherr von Gersdorff, the new chief of staff of the Seventh Army, who had reached their advanced command post three miles north-east of Avranches on the afternoon of 29 July, found a disastrous situation.[59] Nobody had issued orders to blow any of the bridges and no landline communications existed. As a result of the German retreat away from the coast, which had so infuriated Kluge, the American 6th and 4th Armored Divisions were now virtually unopposed.
In Granville, on the coast, the Germans began blowing up the port installations at 01.00 hours and it continued for five hours. The local commissariat de police reported that German soldiers were looting and stealing every vehicle they could find to make their escape south. One American tank platoon even passed within 100 yards of the Seventh Army command post without spotting it. At midnight, Oberstgruppenführer Hausser and his staff pulled out to withdraw east to Mortain.
There was consternation at La Roche-Guyon and at the Wolfsschanze in East Prussia. General Warlimont at Führer headquarters recorded that Kluge was given ‘urgent orders to prevent any penetration into Avranches. Everybody saw that the whole front in Normandy was breaking up.’ Hitler was also concerned about the fate of the 17th SS Panzergrenadier-Division Götz von Berlichingen, which appeared to have been ‘virtually swallowed up’ during the retreat. ‘Nobody ever knew or could figure out what happened to it, despite frantic enquiries. Naturally we were especially interested in this division because the subject of the fighting qualities of an SS division was a “hot iron” — something you could not touch. Hitler was inclined to believe everything which was favourable about his SS troops. He never permitted any reproach against his “black guards”.’
The bulk of the German forces had withdrawn in the direction of Percy. An American reconnaissance troop, trying to find an undefended route to Percy, searched the side roads, but found they were all blocked. On one small country lane, the sergeant in the lead Jeep spotted some German soldiers creeping behind a hedgerow. ‘Pour it to them!’ he yelled to the soldier standing in the back, manning the .50 machine gun. The gunner swept the line, killing most of them with ‘incinerator’ (tracer) bullets. He joked afterwards that the bullets were humane, as they sterilized the wound going in and the one going out the other side. Many soldiers saw it as payback time after all the hard fighting in the bocage.
The Germans had virtually no forces left to defend the coast road. A field replacement battalion on the south side of the River Sienne had rounded up stragglers who had managed to slip through the American screen. The 6th and 4th Armored Divisions, already under Patton’s direction, were well on their way to Avranches. Patton did not accept any excuse for delay. ‘The thing to do is to rush them off their feet before they get set,’ he wrote in his diary on 29 July. He was in an exuberant mood. Breakthrough had been achieved. The breakout, which he felt belonged to him by divine right, was about to begin.
22. Operation Cobra — Breakout
On 30 July, when the 4th Armored Division was in striking distance of Avranches, Montgomery launched Operation Bluecoat. He did not usually mount an offensive in such a hurry. It seems that, once again, the initiative had come from Dempsey, but that did not stop Montgomery from implying that it was his plan. He sent a signal to Eisenhower: ‘I have ordered Dempsey to throw all caution overboard and to take any risks he likes, and to accept any casualties, and to step on the gas for Vire.’
The 13th/18th Hussars were in reserve, carrying out some much needed maintenance work on their tanks, when their brigade commander ‘grinds to a halt in his jeep’ and tells one of their officers that the regiment is due to take part in a battle on Sunday morning. They were to move out at 06.00 hours the next morning. Their tank engines were all in bits and they had to start reassembling them frantically. Some units received only thirty-six hours’ warning.
To move two corps from the Caen front to attack in the far west of the British sector in less than forty-eight hours was a nightmare with the narrow roads. Many units received their operational orders only as they were approaching their start-lines. One of the 13th/18th’s squadron leaders heard a rumour from headquarters and recorded it in his diary: ‘Monty is determined to make us catch up on the Yanks who are doing magnificently. The only difference between us is (a) that their army is twice as big and (b) that we have double the opposition against us.’ Although the proportions were a little exaggerated, British and Canadian troops felt with some justification that they had been fighting the war of attrition against the panzer divisions and now the Americans were getting all the glory in the newspapers.

The identity of this officer is not certain. It might have been Generalleutnant Dietrich Kraiss, the commander of the 352nd Infanterie-Division, although his death is recorded several days later on 2 August.

Hitler, who had approved his appointment, was unaware that Gersdorff had been ready to kill him with a suicide bomb on 21 March 1943 in Berlin.
