After their heroics at Cassino and Anzio, the Fallschirmjäger divisions in Italy retreated north to take up positions alongside their German Army companions on the Gothic Line. By the second half of 1944 the Allies enjoyed heavy superiority in manpower and material in Italy, but there was still a lot of hard fighting to do, especially against the veteran paratroopers.

By the end of the first week of August 1944, the British Eighth Army stood on the Ponte Vecchio, bridging the Arno River in recently liberated Florence, Italy. In conjunction with the US Fifth Army it had just completed a campaign that had kept Axis forces in Italy in full retreat, and Allied leaders were optimistic that they were on the verge of pushing the Germans out of the northern Apennines, sweeping through the Po Valley beyond, and advancing into the Alps, the Balkans and perhaps Austria.

The Allies had liberated Rome in June 1944, and in a two-month summer campaign had pushed the enemy 240km (150 miles) north to the River Arno. Allied forces then ran into the Gothic Line, a series of fortified passes and mountain tops 24-48km (15-30 miles) in depth north of the Arno, stretching east from the Ligurian Sea through Pisa, Florence and beyond. Farther east, along the Adriatic coast where the northern Apennines slope down onto a broad coastal plain, Gothic Line defences were anchored on the many rivers, streams and other waterways flowing from the mountains to the sea. The city of Bologna was the key to the line, being a major rail and road communications hub just to the north of the defensive belt.

With the loss of several veteran divisions to the northwestern theatre after the Allied invasion of France on 6 June 1944, once the British and Americans had reached the Gothic Line they might have remained there for the rest of the war. However, this would allow Axis commanders to hold their positions with a minimal force, thus freeing units for duty elsewhere. In addition, British Prime Minister Winston Churchill was becoming increasingly alarmed at the speed of Soviet advances on the Eastern Front, which he felt threatened Western interests in Eastern Europe and British interests in the Mediterranean. He therefore wanted to press on into the Po Valley, push east into the Balkans and north through the Ljubljana Gap, reaching the Danube Valley, Austria and Hungary before the Red Army (at this time the Americans did not share Churchill's concerns about Soviet intentions or his enthusiasm for campaigns in Eastern Europe). However, the Allies did plan to continue offensive operations in the northern Apennines in the hope of breaking through the Gothic Line.

In August 1944, Field Marshal Sir Harold Alexander commanded the Fifteenth Army Group. This comprised Lieutenant-General Mark Clark's US Fifth Army, made up of IV Corps and II Corps, which held the western portion of the Allied line from the Ligurian Sea at the mouth of the Arno River to a point just west of Florence. To the east was Lieutenant-General Sir Oliver Leese's larger Eighth Army, made up of the Polish II Corps, Canadian I Corps, and British V, X and XIII Corps. It held a line from the Florence area to just south of Fano on the Adriatic coast.

Axis forces in Italy, grouped under Army Group C, were commanded by Field Marshal Albert Kesselring. Opposing Clark's US Fifth Army was Lieutenant-General Joachim Lemelsen's Fourteenth Army, which contained 10 divisions belonging to I Parachute and XIV Panzer Corps. Farther east, opposite the British Eighth Army, was the Tenth Army under General Heinrich von Vietinghoff. It consisted of 12 divisions belonging to LXXVI Panzer and LI Mountain Corps. Other Axis forces in northern Italy comprised the Ligurian Army and the Adriatic Command, which undertook numerous anti-partisan and reserve missions.

General Leese advocated the Eighth Army attacking up the Adriatic coast to Rimini to draw Axis units away from the Fifth Army's front. Clark could then attack the Gothic Line in a secondary assault from Florence directly north towards Bologna, and both armies could then converge on and capture Bologna itself and move to encircle and destroy Axis forces in the Po Valley. The operation was codenamed "Olive".

The operation began on 25 August 1944 with the British V Corps and Canadian I Corps attacking along the Adriatic. Supported by the British Desert Air Force, the offensive rapidly gained ground and Allied forces had penetrated the Gothic Line near the coastal town of Pesaro by 30 August. However, Kesselring soon plugged the breach with the 26th Panzer, 29th Panzergrenadier and 356th Infantry Divisions. The seemingly endless rivers and ridges, plus bad weather, meant Axis units had stalled Eighth Army forces short of their Rimini and Romagna Plain objectives by 3 September.

Clark planned to open his phase of Operation "Olive" on 10 September 1944 with an assault by the two corps under his command. As expected, the Germans began withdrawing to the Gothic Line several days before the advance and initial resistance was light. However, as the advancing forces reached the mountains, the intensity of the fighting increased. The Eighth Army's attack in the east had succeeded in diverting most enemy units away from the Futa Pass and II Giogo Pass areas, except for three regiments of I Parachute Corps' 4th Parachute Division. In the west only the 362nd and 65th Infantry Divisions faced the US IV Corps.

The terrain of mountain peaks, streams, deep valleys and ridges meant small-unit actions predominated, and the paras put up their usual dogged resistance. The Fallschirmjäger had heavily fortified the Futa Pass, but were surprised by the US attacks against the Il Giogo Pass and nearby Monticelli Ridge and Monte Altuzzo. By 18 September, after heavy fighting, I Parachute Corps withdrew to the next set of ridges to establish another defence line. Encouraged at having breached the Gothic Line in at least one sector the Americans continued their offensive, and in response the paras defended each position in a series of intense small-unit actions.

As the Fifth Army continued its offensive, the British Eighth Army resumed Operation "Olive" on 12 September. With overwhelming superiority in tanks, aircraft and troops, the British V and Canadian I Corps smashed through defence lines manned by the 29th Panzergrenadier and 1st Parachute Divisions to capture Rimini, the gateway to the Romagna Plain, on 21 September. In the face of stubborn resistance, heavy rain and mud, the Eighth Army continued its attack and began a three-month operation called the "battle of the rivers". Against adverse weather conditions and fanatical resistance, the Eighth Army made only slow progress.

The weather deteriorates

Poor weather was also having an affect on Clark's progress, that and German resistance. Fog and mist drastically decreased visibility, and torrential rains swelled streams, washed out bridges and created quagmires that made troop and supply movements over mountain trails treacherous. Between 5-9 October, for example, Fifth Army units advanced only 4.8km (three miles) for the loss of 1400 casualties. The Germans were paying a high price for their tenacity, though, especially when they mounted counterattacks. Kesselring therefore ordered his subordinates to conserve their manpower by digging in and conducting a defence in depth rather than trying to retake lost mountain tops (he knew that if the Americans advanced out of the Apennines and entered the Po Valley before winter, Axis forces in Italy would be doomed).

A vicious battle was fought on the Livergnano Escarpment, a steep east-west line of solitary mountain peaks constituting the enemy's strongest natural position in the northern Apennines. The US II Corps' assault began on 10 October. The 85th Division led the primary attack against Monte delle Formiche in the centre of the escarpment, while the 91st and 88th Divisions maintained pressure on the enemy's flanks. The defending units were the 4th Parachute, 94th, 362nd and 65th Infantry Divisions. Supported by air strikes, the 85th Division succeeded in taking Monte delle Formiche that day, while the 91st Division outflanked the Livergnano Escarpment from the west, forcing the Axis units in the area to withdraw on 13 October. However, Axis resistance, rugged terrain and poor weather halted II Corps' advance 16km (10 miles) south of Bologna.

The Allies run out of steam

Kesselring's staff were urging him to retreat to the more defendable Alps. Hitler, however, facing Red Army gains on the Eastern Front and Allied successes in northwest Europe, ordered the field marshal to hold his current positions. As far as the Fallschirmjäger were concerned it was business as usual, as the Americans battled their way from mountain to mountain, and Polish, Canadian, Indian and British troops of the Eighth Army attacked north of Rimini on 15 October in a continuation of the "battle of the rivers". However, not even the Allies could sustain high-intensity operations indefinitely. Between 10 September and 26 October, for example, the US II Corps' four divisions had suffered over 15,000 casualties, and during the same period Eighth Army casualties neared 14,000 men.

In early January 1945 the Allies in Italy ceased large-scale military operations. In addition to the bad weather, five Eighth Army divisions and one corps headquarters had been moved to northwest Europe and Greece, further diminishing Allied capabilities in Italy. Alexander, Clark, Truscott and McCreery, therefore, agreed to go on the defensive and use the winter months to prepare for new offensive operations, scheduled to begin on 1 April 1945. Despite two months of planning and limited offensives, Allied units came to rest on a winter line that had changed very little since late October 1944. The approaching spring would bring a fresh effort by the Fifteenth Army Group as it prepared to renew the offensive in a campaign to take it into the Po Valley. Despite being inferior in manpower, aircraft, armour and artillery, the Germans had displayed remarkable courage and resilience.

As 1945 opened the Allies still faced an organised and determined foe in Italy consisting of 24 German and five Italian fascist divisions. Among the best were those in the German Tenth Army's I Parachute Corps. The Fallschirmjäger were by this time experienced veterans who belonged to relatively intact units. That said, they lacked vehicles, air support and were experiencing shortages of equipment. The first Axis defensive line, along the northern Apennines, protected Bologna and blocked entry into the east-west Po Valley, about 80km (50 miles) farther north. The second defence line was anchored along the River Po, which from its source in northwestern Italy meanders east to the Adriatic Sea. The third line, in the Alpine foothills, extended east and west of Lake Garda. Dubbed the Adige Line, after the river of the same name, these defences were designed to cover a last-ditch Axis withdrawal into northeast Italy and Austria.

The final push

The last Allied offensive in Italy opened on 5 April 1945. On the Adriatic coast, the 26th Panzer, 98th Infantry, 362nd Infantry, 4th Parachute and 42nd Jäger Divisions battled units of the Eighth Army. The Argenta Gap fell on 18 April, which threatened to turn the entire Axis flank.

In the US sector, during the afternoon of 15 April, over 760 heavy bombers of the Mediterranean Allied Strategic Air Force pounded positions held by the 65th Division and 8th Mountain Division of XIV Panzer Corps and the 1st Parachute and 305th Infantry Divisions of I Parachute Corps. The Germans continued to fight, but wavered in the face of a massive ground and aerial onslaught. By 18 April, as Axis defences cracked, the bulk of the US Fifth Army passed west of Bologna. Two days later both the Fifth and Eighth Armies launched high-speed armoured advances from the Apennine foothills towards the River Po crossings. It was now a race between Allied and Axis forces to reach the river first and the Alpine foothills beyond.

A hopeless task

The 1st and 4th Parachute Divisions desperately tried to buy time for small detachments of their comrades to escape. But the Allied onslaught swept aside their defences and annihilated Axis rearguard detachments. Now that the Allies were in the open their overwhelming airpower, which the mountain fighting had negated to a certain extent, could add massive support to ground forces. The rapid advance had created many pockets of Axis soldiers, and special task forces had to be created to mop them up. Eventually over 100,000 Axis troops were forced to surrender in the areas south of the river.

By 24 April the entire Fifth Army front had reached the Po, while to the east Eighth Army units were within a few miles of the River Po by nightfall on 23 April. The Germans had nothing left to stop the Allies crossing the river. The capture of Verona on 26 April brought the Allies up to the final Axis defensive line in Italy: the Adige Line. Though imposing, the Germans now lacked the materiel and manpower to organise a cohesive barrier. Indeed, by this time most Axis units had disintegrated into small groups of harried soldiers retreating as best they could in the face of intense Allied pressure.

Resistance was very light now as the Allies advanced, and the towns of Parma, Fidenza and Piacenza were captured in quick succession. Tens of thousands of Axis prisoners now fell into Allied hands, and the ragged survivors of the battered 1st and 4th Parachute Divisions surrendered at the beginning of May. On the afternoon of 3 May 1945, Lieutenant-General Fridolin von Senger und Etterlin, Vietinghoff's representative, formally surrendered the remaining Axis forces in Italy.
