Participation in World War II
The Mountain Infantry served with the Allies in World War II, taking part in the conquest of the town of Montese in the Italian mountains, and heavily defended by the Germans as a last bastion to block the advance of Allied troops towards the Po Valley. On 14 April 1945, at Montese, three Brazilian soldiers on patrol, Arlindo Lúcio da Silva, Geraldo Baêta da Cruz, and Rodrigues de Souza, were attacked by German forces, who called upon them to surrender (including their own leaders/higher ups); the three men took cover and fired on the enemy until running out of ammunition. They fixed bayonets and advanced, but were killed. In recognition of the bravery of the soldiers, the Germans buried them and erected a cross over their grave with the inscription Drei Brasilianische Helden ("Three Brazilian heroes").

There is a monument honouring the three men of the patrol and the Brazilian mountain infantry.
