Extract from War in the Middle Sea, ch.20
The drive on Rome could only occur once the Allies had built up their strength considerably. General Olry noted, ‘The terrain just south of Rome appears flat, but much of it is reclaimed marshland heavily cross-cut by wide, water-filled ditches, which admirably suits the defensive.’ The Allies had a big advantage in armour, but this proved of limited use in the circumstances. Further east the ground rises to rugged hills, where the Germans had dug in strongly. The Allies had no great numerical advantage. The Germans had some twenty divisions nominally, though most were under-strength, and had plenty of artillery, though General von Rintelen complained frequently of ammunition shortages.
The Allies had also gained air superiority, not only over the battle front but to the north as far as Tuscany. In the summer this was not yet crushing, but would only grow. The Bomber Offensive against Germany had started to make Berlin nervous, so by contrast, its air power in Italy steadily declined. An OKL report complained ‘The Allies have now started to employ improved fighter types in large numbers in the Italian theatre, the British have the new Spitfire IX while the Americans and French have introduced the P-47D. These types outclass the Me109G by a dangerous margin.’ Nothing could be done, however, as all the best German machines had gone to protect the Fatherland.
The Germans had freed Mussolini from captivity and so could employ a handful of Italian units who had stayed loyal to him. However von Vietinghoff and von Rintelen had little confidence in their abilities, fearing for their loyalty - 'Marshal Balbo has now joined the Royal Government, and appealed to the loyalists as one Fascist to another,’ noted von Rintelen. ‘Hard to say what effect this might have, but we do not intend to take the chance.’ The Italian units therefore were mostly used on anti-partisan duties. During the summer a grim guerilla war smouldered in central and northern Italy...
The Germans made a priority of keeping the Allies at the greatest possible distance from Germany. An OKW staff report summarised Hitler’s concern: ‘Our effort must be to keep the enemy south of Rome until the winter, when the weather will impede his operations.’
No-one in Berlin doubted, though, that they faced a tall order. ‘They stand 50km from Rome, with at least six months of fair weather in prospect, perhaps seven,’ noted the OKW. ‘The summer weather will give their air power ample scope for operation, and we must expect the weight of air attacks to only increase.’ This point was borne out by the failure of the Valmontone counter-attack in early June, which the Germans attributed to the weight of Allied air power and artillery.
The long exposed coastline of southern France and northern Italy gave the Germans additional worries. ‘The enemy have performed many amphibious landings, they have mastered the technique,’ noted von Rintelen. ‘We need to retain a strong reserve to counteract this. But enemy sea and air power has hitherto meant that once a beach-head establishes itself, we cannot drive them back into the sea.’ The Germans particularly feared a descent upon the south of France, an anxiety which the French sought to aggravate. In part they made overt efforts by expanding airfields in Corsica and mounting numerous air raids on the Riviera coast; in part their effort was invisible, with elaborate deception efforts, such as deceptive radio traffic, made by EMME, the ‘Bakers’, who had by this time relocated to Bastia…
The Allies, however, had no intention of mounting any large amphibious operations, whether in Italy or France. In part this was due to a lack of landing sites in the area west and north of Rome. ‘We looked at Santa Severa, but the enemy have planted it thick with wire, mines and machine-gun nests. We also looked at sites between Livorno and Civitavecchia, but landings so far north would depend on base facilities in Corsica, which are not yet adequate. Besides, as usual, the same old problem,’ wrote General Olry in May. ‘Not enough landing craft. Attrition has been bad, and now the British have taken all their LSTs back, to train for OCEAN. I would like to take Rome this year, it would comfort us for the prolongation of our country’s suffering. London too would like Rome this year, but still more they want to please Washington. As for Washington, they have high hopes for Borneo, and their main interest in the Mediterranean is in the preparations for PRECIPICE.’
The Algiers government disliked its weak bargaining position, but could do little about it. ‘We depend so much on the Americans, we must defer on this grand strategic question,’ noted Mandel to de Gaulle. ‘But we do not have to like it.’ The Americans did agree to support one amphibious operation off the Italian coast, namely operation BRASSARD, the capture of Elba, which French troops carried out in June. ‘This gives the enemy artillery positions within range of the coast at Piombino,’ noted OKW nervously, ‘thus further complicating our supply problems.’
The offensive on Rome would take the form of a conventional land battle. Preliminary operations in the hills, the accumulation of stores, and the improving of the air position, occupied the late spring and early summer. June also saw a brief diplomatic incident when General Gott’s staff used the great abbey at Monte Cassino as a headquarters, leading to a German air raid that damaged the building, and strong protests from the Vatican. Gott, who Brooke considered exhausted, now went back to London, General McCreery replacing him in command of 8th Army...
Operation MASQUE commenced in late July and two months of bitter fighting followed, which cost the Allies over 50,000 casualties, mostly American, by far the most costly campaign of the war so far for them. ‘We thought Corsica had been tough, but we hadn’t seen the elephant yet,’ wrote one US infantryman of the 34th Division. ‘Heat, dust, mosquitoes and death, every day for weeks on end.’ The Allies had placed great hopes in the massed use of armour, especially the Sherman tank, which had now for the first time fully replaced older models among the US and French forces. It generally performed well, but most of the hard yards had to be gained by infantry, usually after heavy bombardments. After one costly failed attack in August, General Patton suffered a breakdown and was relieved of command. ‘We need him, so send him on leave - we can’t have George go crazy,’ noted the President, ‘or at least, not any crazier.’
...US air power repeatedly proved the factor that gave the Allies the edge, but this came at great cost. On September 5th US bombers attacked railway targets in and around Rome, but suffered heavy losses after missing the rendezvous with their fighter escorts. ‘Fifty planes gone, destroyed and damaged, in one go,’ noted General Clark, the new commander of 5th Army, ‘that hurts.’ The losses however spared the little town of Castelgandolfo, with its Papal palace, from destruction, as they forced cancellation of a planned air raid against the place. ‘Just as well in my opinion,’ noted Clark. ‘Attacking under the Alban hills was a mistake. We need to rest II Corps. The Germans need flanking out of Rome, and Bethouart thinks he has the men to do it.’
General Bethouart’s XIX Corps, mainly Moroccans and Algerians, had trained intensively for this operation, and in less than a week they pushed through the hills between Avezzano and L’Aquila that had hitherto resisted repeated Allied efforts. The French thus struck the decisive blow that drove the Germans out of Rome, though they did not reap the reward themselves of capturing the place: that honour went to US II Corps on 2nd October, with French units following. General Clark had hoped to take the surrender, but he suffered a car accident outside Frosinone that kept him in hospital for a week. ‘Still he deserves as much as anyone to be called the liberator of Rome,’ noted Marshal Balbo. Instead on the 3rd General Bethouart rode into the Piazza Venezia aboard a Sherman tank, to the acclamations of the people.
Hitler then replaced General von Rintelen with von Vietinghoff as supreme commander in Italy, but he could do no more than extract most of his forces from the trap that began to close with the simultaneous breakthrough of 8th Army further east. ‘The Allies did nothing especially smart, except for the French breakthrough in the hills,’ von Vietinghoff wrote. ‘But then, with their air power, they had small need for cleverness.’ The Allies continued the pursuit as far as the Civitavecchia - Pescara line, where the front stabilised in October, then became static for the winter.
