Morale fell among Italian soldiers who lived a tedious life when not on the front lines, as they were forbidden to enter theaters or bars, even when on leave. However, when battles were about to occur alcohol was made freely available to the soldiers in order to reduce tension before the battle. In order to escape the tedium after battles, some groups of soldiers worked to create improvized whorehouses. In order to maintain morale, the Italian army had propaganda lectures of the importance of the war to Italy, especially in order to retrieve Trento and Trieste from Austria-Hungary. Some of these lectures were carried out by popular nationalist war proponents such as Gabriele D'Annunzio. D'Annunzio himself would participate in a number of paramilitary raids on Austrian positions along the Adriatic Sea coastline during the war and temporaly lost his sight after an air raid. Prominent pro-war advocate Benito Mussolini was prevented from giving lecture by the government, most likely because of his revolutionary socialist past.
