on 24 May 1915, San Marino remained neutral and Italy adopted a hostile view of Sammarinese neutrality, suspecting that San Marino could harbour Austrian spies who could be given access to its new radiotelegraph station. Italy tried to forcibly establish a detachment of Carabinieri in the republic and then cut the republic's telephone lines when it did not acquiesce. Two groups of ten volunteers joined Italian forces in the fighting on the Italian front, the first as combatants and the second as a medical corps operating a Red Cross field hospital. The existence of this hospital later caused Austria-Hungary to suspend diplomatic relations with San Marino. After the war, San Marino suffered from high rates of unemployment and inflation, leading to increased tensions between the lower and middle classes. The latter, fearing that the moderate government of San Marino would make concessions to the lower class majority, began to show support for the Sammarinese Fascist Party (, PFS), founded in 1922 and styled largely on their Italian counterpart. PFS rule lasted from 1923 to 1943, and during this time they often sought support from Benito Mussolini's fascist government in Italy. During World War II, San Marino remained neutral, although it was wrongly reported in an article from The New York Times that it had declared war on the United Kingdom on 17 September 1940. The Sammarinese government later transmitted a message to the British government stating that they had not declared war on the United Kingdom. On 28 July 1943, three days after the fall of the Fascist regime in Italy, PFS rule collapsed and the new government declared neutrality in the conflict. The PFS regained power on 1 April 1944, but kept neutrality intact. Despite that, on 26 June 1944, San Marino was bombed by the Royal Air Force, in the belief that San Marino had been overrun by German forces and was being used to amass stores and ammunition. The Sammarinese government declared on the same day that no military installations or equipment were located on its territory, and that no belligerent forces had been allowed to enter. San Marino accepted thousands of civilian refugees when Allied forces went over the Gothic Line. In September 1944, it was briefly occupied by German forces, who were defeated by Allied forces in the Battle of San Marino. San Marino had the world's first democratically elected communist government – a coalition
