Allied invasion of Sicily and fall of Mussolini On 10 July 1943, the Allies
invaded Sicily. The Axis lost the island after weeks of bitter fighting, but succeeded in ferrying large numbers of troops to the Italian mainland. On 19 July, an Allied
air raid on Rome hit railways yards, a steel works and an airport, and damaged to homes near the targets. Subsequently, popular support in Italy for the war collapsed. On 25 July, the
Grand Council of Fascism voted to limit the power of Italian dictator Benito Mussolini and handed control of the Italian armed forces over to King
Victor Emmanuel III. The next day, Mussolini met with the King, was dismissed as prime minister, and then imprisoned. A new Italian government, led by General
Pietro Badoglio and Victor Emmanuel III, took over in Italy. Although they publicly declared that they would keep fighting alongside the Germans, the new Italian government began secret negotiations with the Allies to come over to the Allied side.
Armistice with the Allies and German invasion Throughout August 1943, fearful the Germans may try to rescue Mussolini, Badoglio had the deposed dictator transferred from one secret location to the next. On 3 September, an
armistice was signed with the Allies in Sicily, but not made public straight away. That very day, British troops crossed the short distance from Sicily to the 'toe' of Italy in
Operation Baytown, but the Badoglio government wanted an Allied landing near Rome before openly defecting, as the news would certainly spark war with Germany. Indeed, according to Goeschel, Hitler had for weeks been infiltrating German soldiers into Italy and preparing a coup to reinstall Mussolini. A landing close to Rome was considered risky by the Allies, but further invasions at
Salerno (South of Naples) and
Taranto (on Italy's 'heel') were scheduled for 9 September. On 8 September, the Allies became tired of Rome delaying a public announcement, and broadcast the news of the armistice on the radio, forcing Badoglio's hand. Later that day, the German Ambassador in Rome,
Rudolf Rahn, was officially informed by the Italian government of the armistice. He replied it was, "a betrayal of the given word". The German military responded immediately by
invading. Italian forces were disarmed, by force when met with resistance, and northern and central Italy were occupied, along with Italian-occupied zones in France and the Balkans.
Skirmishing on the outskirts of Rome between elite German Parachute and Panzer Grenadier divisions and the Italian army began on 8 September 1943. King Victor Emmanuel III and his family, with Marshal Badoglio, General Mario Roatta (the Army Chief of Staff), and others, fled Rome on 9 September, and headed to Allied-controlled
Brindisi, which for the next few months became the Kingdom of Italy's seat of government. However, the sudden departure of the senior figures in the government and high command left a power vacuum, which created confusion among Italian military commanders and demoralised personnel. Italian troops in Rome made a last stand at
Porta San Paolo on 10 September, then the city was surrendered. As part of the terms of the armistice, the Italian fleet was to sail to Malta for internment; as it did so, it came under air attack by German bombers, and on 9 September two German
Fritz X guided bombs sank the Italian battleship off the coast of
Sardinia. On the Greek island of
Cephallonia, General
Antonio Gandin, commander of the 12,000-strong Italian
Acqui Division, decided to resist the German attempt to forcibly disarm his force. The battle raged from 13 to 22 September, when the Italians capitulated having suffered some 1,300 casualties. Following the surrender,
the Germans proceeded to massacre thousands of the Italian prisoners. Italian troops captured by the Germans were given a choice to keep fighting with the Germans, and the 615,000 who refused were designated
Italian military internees and were transported as forced labour to Germany, of whom 30,000 died in captivity. Some Italian troops who evaded German capture in the Balkans joined the partisansapproximately 40,000 in Yugoslavia and 20,000 in Greece.
The RSI, co-belligerence and resistance on 12 September 1943 On 12 September 1943, Mussolini was rescued from imprisonment at
Gran Sasso by the Germans in
Operation Eiche. Once in northern Italy, he was installed as the head of a German puppet state, the
Italian Social Republic or RSI, and leader of the new
Republican Fascist Party. After the German invasion,
deportations of Italian Jews to Nazi
death camps began. In October 1943, Nazis raided the Jewish ghetto in Rome. In November 1943, Jews of
Genoa and
Florence were deported to
Auschwitz; the same month saw Italy's Fascists at a
congress in Verona declare Italian Jews as foreign enemies. According to Goeschel: "While the order for the deportations came from Germany, they would not have been possible without the assistance of RSI officials, including the police, and the opportunism of some ordinary Italians who became complicit in the persecution of Jews through denunciations, casting into doubt the powerful post-war stereotype of Italians as incapable of inhumanity and anti-Semitism." (27–30 September 1943) The Allied armies continued to advance through Italy despite increasing opposition from the Germans. The Allies soon controlled most of southern Italy, and
Naples rose against and ejected the occupying German forces. From a domestic Italian perspective, the conflict now began to resemble a civil war between the Fascists who collaborated with the Germans versus pro-Allied Italian forces, including those loyal to the King of Italy, plus resistance fighters in the Nazi-occupied areas. in June 1944 On 13 October 1943, the Kingdom of Italy formally became a co-belligerent of the Allies by declaring war on Nazi Germany. With Allied assistance some Italian troops in the south were re-organized into what were known as "Co-belligerent" or "Royalist" forces, although at first some among the British and Americans were reluctant to trust and arm former-enemies. Autumn 1943 saw the Co-belligerent Army raise its first combat unit, I Motorized Grouping, which was made up of troops who had served in two former-Italian Army divisions, the
Legnano and the
Messina, and avoided capture by the Germans following the Armistice. I Motorized Grouping first saw action against Axis forces in December 1943, fighting alongside the
US II Corps at the
Battle of San Pietro Infine, where it suffered heavy casualties but impressed the Americans enough for the commander of the
US Fifth Army,
General Clark, to send a message of congratulations to the commanding officer,
General Dapino. The Allies consequently provided the equipment and resources to expand this force, which become the
Corpo Italiano di Liberazione (CIL). Further expansion saw the CIL replaced by six 'Combat Groups', each consisting of two infantry regiments and one artillery regiment. They were re-equipped with British uniforms, helmets and weapons. US General
Mark W. Clark said of the Co-belligerent Army, “The Italian regular units took some heavy losses and fought well in the last year of the war”. The army of the RSI was the
National Republican Army or ENR, which mostly saw action against the partisans. Established with those troops who had agreed to continue fighting for the Axis, it was then expanded by recruiting in the camps holding Italian military internees in Germany. This created issues of loyalty, as some internees joined the ENR simply to escape the appalling conditions in the camps. Attached to the ENR were a number of autonomous combat units. The RSI had a large gendarmerie called the
National Republican Guard or GNR, which was responsible for internal security, particularly fighting the resistance. There were also local militias, known as the
Black Brigades, who had a reputation for brutality and fanaticism. In late 1943, a regiment of Italian
Waffen-SS volunteers was formed, which by 1945 had expanded into a division, the
29th Waffen Grenadier Division of the SS (1st Italian). The other major combat force in the civil war was the large
Italian resistance movement located in central and northern Italy, which fought a guerrilla war against the German and RSI forces. The first Partisans were mostly Italian military personnel who avoided capture in the September 1943 German invasion, and began fighting a guerrilla war. They were joined by civilians, escaped Allied POWs and agents from the
Office of Strategic Services (OSS) and
Special Operations Executive (SOE). While the resistance spanned anti-fascists from a wide political spectrum, as well as the apolitical, there was a preponderance of communists and socialists, reflecting the more industrialised economy of northern Italy. In May 1944, General Alexander, commander of Allied
15th Army Group, estimated six Axis divisions in northern Italy were tied up fighting partisan groups. In the summer and autumn of 1944, there were a number of
partisan republics established, which briefly operated free of the RSI and the German occupation forces, but all were over-run by Axis forces within weeks or months of establishment. It has been estimated that by spring 1945, around 300,000 people were fighting with the partisan forces.
Allied advance and liberation of Italy Allied progress on the Italian mainland was slow and difficult, hindered by mountainous terrain, fast-flowing rivers and the narrowness of the peninsula, which meant the battle favoured the defender. Axis forces were able to retreat from one fortified line to the next, the strongest being the
Winter Line and the
Gothic Line, resulting in a difficult campaign for the Allies. , Rome, in March 1944 As the Allied advance drew nearer to Rome, resistance activity in the city intensified. One of the most famous partisan attacks in the capital happened on
Via Rasella on 23 March 1944. A company of
SS Police Regiment Bozen, around 156 fully-armed military policemen, were marching down Via Rasella (at the same time they did every day) when ten kilos of dynamite hidden in a street cleaner's cart exploded. Then a dozen partisans of the Gruppo d'Azione Patriottica ("Patriotic Action Group"), or GAP, attacked with small arms and hand grenades, leaving 33 of the SS gendarmes dead and 100 wounded. The Germans responded with the
Ardeatine massacre, where 335 Italian prisoners (75 of whom were Jewish) were murdered. Following protracted and heavy fighting at the
Battle of Monte Cassino (where Co-belligerent Army Alpini captured the strategic summit of
Monte Marrone) and the
Battle of Anzio, the Allies broke through and took Rome on 4 June 1944, two days before the
Normandy landings in France. At the
Battle of Ancona (16 June–18 July 1944), the Co-belligerent
IX Assault Unit achieved an important breakthrough at
Osimo, although Ancona was for the most part a Polish victory. Despite the sluggish advance for the Alliesin part due to veteran Allied divisions and commanders being withdrawn from Italy to participate in the invasion of France (both for the landings in Normandy and the
Côte d'Azur), plus other resources being divertedthe Italian Campaign played an important role in the defeat of Nazi Germany. By the time the Allies reached the Gothic Line, 26 Axis divisions were tied-up fighting in Italy that otherwise could have been committed to other fronts. As the pendulum of likelihood swung steadily towards an Allied victory in the war, many Italian industrialists who had supplied the Fascist and Nazi war effort, in the words of Behan, "began to face both ways"; continuing to deliver on orders to the Axis while simultaneously passing money and other help to the resistance. Once an Axis defeat began to look inevitable, this became a case of wanting to "extricate themselves from recent alliances and bet on partisan horses". in Milan during the final insurrection leading to the
liberation of Italy in April 1945 The final and total Allied victory over the Axis in Italy was secured by the
spring offensive of 1945. Between 9 April and 21 April, the Co-belligerent army’s
Combat Group Friuli and the Partisans were part of a multinational Allied force that fought the
Battle of Bologna, liberating the city alongside British, Gurkha, Polish and South African troopswith the Polish first into the city, greeted by Partisans. On 25 April, the umbrella organisation for the partisan groups in the north, the
National Liberation Committee for Northern Italy, declared a
general insurrection, and as a result several important cities in the north were liberated by resistance fighters before Allied troops arrived, including Genoa, Milan and Turin. This greatly assisted the Allied advance, and 25 April is now a national holiday in Italy. Mussolini was
captured and killed on 28 April 1945 by partisans while attempting to flee. The surrender of German and RSI forces in Italy occurred on 2 May, shortly before Germany finally surrendered ending World War II in Europe on 8 May. ==Casualties==
