The Battle of Rimini took place between 13 and 21 September 1944 during Operation Olive, the main Allied offensive on the Gothic Line in August and September 1944, part of the Italian Campaign in the Second World War. Rimini, a city on Italy's Adriatic coast, anchored the Rimini Line, a German defensive line which was the third such line of the Gothic Line defences.
Rimini, which had been hit previously by 373 air raids, had 1,470,000 rounds fired against it by Allied land forces; by the end of the battle, only 2% of all buildings in the city escaped damage.
Background
Rimini during the Second World War
Rimini is located in a militarily strategic position, at the southern tip of the Po Valley, at a narrow passage along the Adriatic coast where the plains of northern Italy meet the mountainous terrain of central Italy.
Before the Battle of Rimini, Rimini had suffered sustained Allied aerial bombardment since November 1943. Many refugees from northern Italy had fled to Rimini between November 1942 and February 1943, only to flee again with the bombings. Of 40,000 inhabitants, only 3,000 remained, and the city centre was deserted. Around 55,000 refugees fled to the north, to the hinterland, and to the independent Republic of San Marino, where they sheltered in the country's railway tunnels. As the Allied frontline approached the city, naval bombardment followed, and remaining citizens hid in makeshift shelters or in the caves by the Covignano hill. Partisan resistance was also notable in Rimini, with official reports of 400 young people involved in resistance cells. On 16 August 1944, three partisans were hanged in Rimini's central square, which would later be renamed in their honour.
Between November 1943 and September 1944, the total number of air, naval, and land bombings in the city numbered 396, destroying 82% of all buildings, the highest figure among Italian cities with over 50,000 inhabitants.
The Gothic Line
On 25 August 1944 the Eighth Army launched Operation Olive, attacking on a three Corps front up the eastern flank of Italy into the Gothic Line defences. By the first week in September, the offensive had broken through the forward defences of the Gothic Line and the defensive positions of the Green I line and United States Fifth Army entered the offensive in central Italy attacking towards Bologna.
In the Eighth Army's centre, the 1st Canadian Division had broken through Green II on the right of its front advancing to pinch out the Polish Corps on the very right of the army (and allowing the latter to be withdrawn to army reserve) but inland in the hills, the Corps' advance had been held up by stubborn defence at Coriano and V Corps on the army's left flank had been halted at Croce and Gemmano. A new attack to clear the Green II positions in the hills and destroy the Rimini Line running from the port of Rimini inland to San Marino was scheduled to start on 12 September.
Prelude
Arrival of the front in Riccione
In Riccione, a sizeable town southeast of Rimini, from the evening of 2 September, the Germans retreated to a defensive line at the Rio Melo, defended by a single tank, allowing forces of the 1st Canadian Division to enter the town. The area between Viale Ceccarini, Riccione's principal high street, and the Rio Melo, a river lined with a port, became a no man's land until the Battle of Rimini had finished. The Hotel Adria, no longer extant, was requisitioned for soldiers engaged in the Battle of Rimini to take four days' leave on the beach.
Behind the Canadian Division was the 3rd Greek Mountain Brigade (Greek: ΙΙΙ Ελληνική Ορεινή Ταξιαρχία). On 8 and 10 September, near the village of Cattolica, the Greeks pushed back two German attacks.
3–12 September: Battle of San Lorenzo in Strada
To Riccione's northwest, the ancient town of San Lorenzo in Strada was heavily fortified by General Richard Heidrich's 1st Parachute Division, who barricaded themselves in the church with instructions to fight until the end. San Lorenzo sat on a hilltop along a curve in the Via Flaminia before Rimini airfield, and was therefore strategically important.
On 3 September, the 1st Parachute Division engaged the Canadians, who had reached Riccione's southern outskirt of Abyssinia. The battle in San Lorenzo, which included sword-fighting in the church, claimed 31 soldiers and 124 wounded or missing, with the Canadians reduced to 18 men before they suspended their attack on 6 September.
By 12 September, the Greeks had joined the Canadians in Riccione, with orders to lead the right flank during the Canadians' offensive on Rimini. The Greeks were notorious for their poor behaviour towards locals and consequently ordered not to pass underneath the railway that bisected Riccione. On the night of 12–13 September, a second attack on San Lorenzo, supported by the 3rd Greek Battalion and the 20th New Zealand Armoured Regiment, claimed the church after four and a half hours. The church was destroyed.
Battle
13–14 September: Battle of Monaldini and Monticelli
On 13 September, the 3rd Greek Mountain Brigade, supported by the combined armour and infantry of the B squadron of the 20th New Zealand Armoured Regiment and the 22nd Motor Battalion from the 2nd New Zealand Division, launched an attack to take Rimini. Supporting the brigade were infantry, mortars and machine guns from the Canadian Saskatoon Light Infantry, and 33 17pdr guns from New Zealand.
Initially, the Greeks attacked Monaldini and Monticelli, two small agricultural hamlets about 500 metres (1,600 feet) southwest of San Lorenzo. The settlements were defended by the 1st Parachute Division and some Osttruppen described as Turkomen (likely a Turkestani Ostlegion battalion from the 162nd Turkoman Division). The Germans were well prepared and held off the Greeks, who lost almost one hundred troops, more than a third of the troops engaged since the beginning of the action.
During the night of 13–14 September, the 1st Canadian Brigade gathered on the southern bank of the Marano Stream, north of San Lorenzo in Strada. The Greeks launched a night attack at 02:00, supported by the 3rd Canadian Brigade, followed by the 1st Canadian Brigade at 06:30.
On 14 September, 7 and 8 troops of the B Squadron were added to the attack on Monaldini. Soon after, a platoon from 22nd Motor Battalion aided the attack on Monticelli with the support of 5 and 6 Troops' Sherman tanks. By 20:00, Monaldini had been taken with only light casualties. The Greek and New Zealand forces turned to Monticelli, but the German defenders abandoned the settlement as soon as they approached.
15–17 September: Battle of Rimini Airfield
On 15 September, the Greeks launched an assault on Rimini airfield, west of the village of Miramare. The airfield had been used as a prisoner-of-war camp for captured Allied soldiers.
At 10:00, the 1st Greek Battalion crossed the Marano Stream at the southern end of the airfield, and immediately came under intense fire from German positions around the airfield. The Greeks halted to reorganise themselves for an attack. C Squadron of the 18th New Zealand Armoured Regiment relieved B Squadron 20th Armoured Regiment in the line supporting the Greeks. After requesting air support, Allied fighter and bomber planes attacked the western side of the airfield, and the Greeks attacked shortly afterwards.
The 1st Greek Battalion, which attacked the airfield, was heavily resisted. Fire from the airfield inflicted heavy casualties on the advancing Greeks; however, support from the New Zealand tanks and infantry was well-coordinated as one of the New Zealand officers spoke Greek. The tanks fired on each house lining the south of the airfield to ensure that they were not occupied. As the Greeks and New Zealanders approached the defensive positions, they came under fire from infantry, Panzerschreck anti-tank rockets, self-propelled guns, and emplaced Panther turrets. The heavy fire pinned the advance just short of the airfield. Meanwhile, the tanks edged around a hedgerow to avoid the anti-tank fire, but soon found themselves at the forefront of the attack. A German self-propelled gun knocked out a Sherman, but the New Zealanders continued forward and knocked out enemy positions with high-explosives and grenades, forcing the Germans to withdraw from their positions. The crew of a Panther turret abandoned it during the night.
Separately, the 2nd Greek Battalion, to the right of the 1st Greek Battalion, attacked up the Via Flaminia, but became separated from their supporting New Zealand tanks. The Greeks were halted by mines and heavy defensive fire from the eastern side of the airfield and nearby houses.
On the left flank, the 3rd Greek Battalion attacked the hamlet of Casalecchio, a crossroads with a few houses and a church, supported by New Zealand tanks and infantry. The Greeks quickly cleared the houses, but the church was defended by paratroops. A combined attack by Greek and New Zealand infantry and tanks drove the paratroopers out. Heavy machine-gun and mortar fire from the airfield halted any further advance.
On 16 September, the Greeks continued to mop up around the airfield, most of which they held, though one Panther turret was still in operation. The 3rd Greek Battalion advanced up the left through the hedges and ditches beyond Casalecchio until they came level with the 1st Greek Battalion in the centre. They were under constant fire and had to clear several landmines. On the right flank, the 2nd Greek Battalion advanced. Anti-tank fire was lighter than the previous day.
On 17 September, the three Greek battalions continued their advance. Several attempts were made to knock out the remaining Panther turret with aircraft and artillery, but it finally fell to one of the New Zealand Shermans working around its flank. It fired several anti-tank rounds into the turret before the crew eventually evacuated. With the airfield was taken, the 3rd Greek Mountain Brigade turned its attention towards Rimini itself.
18–20 September: Approaching Rimini
With the airfield captured, the offensive to retake Rimini began in earnest on 18 September. The 2nd and 3rd Battalions pushed towards Rimini from the southeast. Supported by the New Zealand regiments, they encountered heavy resistance once again from the German paratroops. Meanwhile, to the southwest, the 1st Canadian Division was contesting the area of San Fortunato, on the Covignano hill overlooking Rimini, with over a million artillery strikes on the hill alone. The Canadian attack, which had broken the German defence by the morning of 20 September, threatened the defending forces with being outflanked. Despite the Queen's Bays' armoured column being destroyed at Montecieco, the German troops were forced to retreat to Vergiano and the Marecchia river, chased also by the Indian divisions returning from the Battle of San Marino.
By 16:30 on 20 September, the battalions were in the southern outskirts of Rimini, with the 2nd Greek Battalion having captured the Church of Colonnella. Rimini had been the site of 700 artillery strikes and 486 aerial raids, and 90% of its buildings had been razed. Albert Kesselring, in charge of the German defence in Italy, suggested that soldiers defend the city to exert maximum damage on the attacking forces. General Heinrich von Vietinghoff established a defensive line north of the Marecchia river, and persuaded Kesselring, also in light of a heavy rain that evening that began at 18:00, that any unsupported defence of the city would not last long. At 19:30, the German forces were ordered to retreat overnight.
To slow down the Allied advance, buildings were demolished at street corners, alongside most bridges over the Marecchia River. Marshal Willi Trageser of the 2nd Parachute Division was charged with destroying both the Arch of Augustus and the Ponte di Tiberio, Rimini's definining Augustan monuments at either end of its decumanus maximus. Trageser defied Lieutenant Kenneth Renberg's orders to demolish the arch, saying after the war:
I personally gave the order not to blow up the arch, taking full responsibility for it. It seemed absurd to me to destroy a historical monument of this kind to achieve no result, given that the arch was isolated in the middle of a square and, therefore, traffic could have continued perfectly well, both to the right and left of the monument itself.
