Hitler’s thinking so far had been to play for time. He had reckoned that further dogged German resistance would ensure that the Allies continued to make only slow progress. His priority in the west was to hold the U-boat bases on the French coast, essential for the war in the Atlantic on which so much still hinged, in his view, and fanatical defence of the harbours to deny the Allies the possibility of large-scale troop reinforcements. Containing the Allies in north-western France and gaining time would allow defences to be strengthened and preparations made for a major German offensive, an idea already germinating in Hitler’s mind. Inflicting a defeat on the western Allies and halting their presumed march to victory would then force them into armistice negotiations.2
He was now faced, however, with the implications of the Allied capture of Avranches. It was an ominous development. Characteristically, he chose not to respond by withdrawing German troops to new lines to the east. Instead, he commissioned Field-Marshal Hans Günther von Kluge—whose idea it had originally been—to launch a quick counter-offensive westwards through Mortain, aimed at retaking Avranches, splitting the American forces and re-establishing the German lines. Kluge’s attack took place in the early hours of 7 August, but was effectively over after a single day. German troops did succeed in regaining Mortain and advancing about 11 kilometres. But, subjected to ceaseless bombardment, they could get no further. By insisting on Kluge continuing the attack long after wisdom dictated swift withdrawal, Hitler invited disaster. Since Kluge faced increasing danger of encirclement by American forces, Hitler eventually allowed a retreat from the Mortain area on 11 August, but as late as 15 August refused Kluge’s entreaty to withdraw 100,000 troops in great peril near Falaise.
Hitler’s suspicions of his field-marshal boiled over when he could not reach him by radio that day, and he peremptorily dismissed him from his command, replacing him by the trusted troubleshooter, the tough and unyielding Field-Marshal Model. Soon afterwards, correctly fearful that he would be put on trial before the dreaded People’s Court for his connection with the conspiracy against Hitler (even though he had been careful not to join the plot), Kluge committed suicide. Model eventually extricated around 50,000 men from the rapidly tightening ‘Falaise pocket’. But roughly the same number were captured and another 10,000 men killed, while huge quantities of armaments and equipment had to be abandoned. During August, the German army in western Europe had in all lost over 200,000 men killed, injured or captured.3
It had been a disaster. A full-scale German retreat turned into little short of a rout. It could even have been worse had the Allies pressed home their advantage, closed the pocket enveloping the German troops, and prevented so many hardened warriors and seasoned officers from escaping to fight again another day. Even so, the Allies could now race northwards and eastwards. German morale seemed on the verge of collapse.4 When Paris fell on 25 August, it was without a fight. Withdrawal was also under way from parts of Belgium and Luxemburg. By the end of August, some 2 million Allied soldiers were already in France, others rapidly adding to that number. To the north, the Allies could drive on to the Channel ports. The Allied push into Belgium brought the liberation of Brussels on 3 September and, next day, the capture of Antwerp. Meanwhile, American and French troops had landed on the coast of southern France on 15 August. By late that month they had taken Marseilles and advanced on Lyons. It was little wonder, then, that Allied optimism peaked around this time. The Germans, it seemed, could not last through the winter. The war was approaching its final stages. It would all soon be over.
Unexpectedly, however, the Allied advance stalled. The aim evinced at the beginning of September by the Allies’ supreme commander, General Dwight D. Eisenhower, of pressing forward to the Reich borders on a broad front before German defences could be consolidated soon proved an impossibility.
The Allies fared worst in the northern sector. Serious tactical errors brought the advance there to a halt. The arrogant British commander, Field-Marshal Bernard Montgomery, impatient to exploit the German disarray and press boldly ahead into the Ruhr and on to Berlin, made costly mistakes that vitiated his aims—headstrong and immensely risky as these would have been anyway. The conflict of strategy and personality between Montgomery and Eisenhower was unquestionably damaging to the Allies at this vital time. Montgomery’s failure to exploit the important capture of the undestroyed Antwerp port by pressing forward to secure the Scheldt estuary left the crucial port unusable until the end of November and allowed large numbers of German troops who could have been cut off in the area to escape. This was compounded by the disaster at Arnhem, where Montgomery’s insistence on a daring airborne assault to cross the Rhine resulted in high British losses. The risky offensive ‘Market Garden’ began on 17 September but was in effect already over three days later. From then on, hopes of a rapid advance across the Rhine and into Germany’s industrial heartland, the Ruhr, had to be abandoned.
On the southern sector of the front, the US Third Army under General George Patton had sped eastwards during the second half of August, crossed the Meuse and reached the Mosel. Patton was optimistic that he could drive on into Germany, and that the war could be rapidly won. The first step was to press over the Mosel into Lorraine. The important industrial belt of the Saar beckoned thereafter. But in early September Patton’s advance slowed almost to a halt. His supply line to Cherbourg was almost 650 kilometres long. His tanks were simply running out of fuel. And Eisenhower had given priority for the time being to Montgomery’s intended drive into the Ruhr. A furious Patton was held back. As his rapid advance became almost immobilized, German defences facing his attacking forces were urgently strengthened and placed under the command of the redoubtable General Hermann Balck, battle-hardened from the eastern front and high in Hitler’s favour. The momentum had been lost. It would be a further two months and much hard fighting before fierce German resistance at Metz, the fortress heartland of Lorraine, would be overcome.5
The best prospects lay in the central sector of the front. The US First Army, under General Courtney Hodges, advancing north-eastwards from the Paris area in late August, had destroyed several German panzer divisions, taking 25,000 prisoners, before reaching Mons, in Belgium. Part of the army, the V US Corps, then turned south-east to advance through Luxemburg and almost to the German border near Trier by 11 September, while the VII US Corps drove directly eastwards towards Aachen. Around 6 p.m. on 11 September, the first American troops set foot on German soil, just south of Aachen, a city by now largely free of defending troops and with a panic-stricken population. But the Americans pressed their advance over too wide an area. German forces regrouped and, through tenacious fighting, blocked the larger and stronger American forces. Within five days, reinforced German units had succeeded in repulsing the American attack. German authorities were able—for the time being—to restore their control over Aachen and prevent any American breakthrough in the direction of Cologne. Another chance had been missed. It would take a further five weeks of bitter fighting before Aachen became the first German city to fall into Allied hands, on 21 October. And it would be nearly six months before Cologne, only 90 kilometres or so away, was taken.
Meanwhile, Rundstedt had been recalled as Commander-in-Chief West (in overall command of the army in that theatre) on 5 September, leaving Model, a brilliant defence strategist, to take charge of Army Group B (one of two Army Groups on the western front; the other, Army Group G, was commanded by Colonel-General Johannes Blaskowitz). Under Model’s command, the German defences, helped by shortened supply lines and hardened reinforcements, both salvaged from Normandy and brought across from the eastern front, had been strengthened. By mid-September the Allies stood close to the German border over a long stretch of the front from Belgium almost to Switzerland. But it was now clear that expectations which the Allies had held for months, drawing on the experiences of the First World War, of the sort of German collapse that had happened in 1918 were misplaced.6 The war was set to drag on.7
