[2] After seeing the success that the Garibaldian campaign was having in Sicily, Beniamino Caso realized the value in creating a military troop to rebel against the Bourbon power, and in June 1860 in Piedimonte he assembled a group of liberal volunteers with the aim of overthrowing it.

[3] On 18 August Beniamino Caso and Pasquale Casella travelled to Naples to personally pick up the weapons and the flag of the newly born legion.

The two entered Piedimonte Matese the night of 24 August 1860 with the flag, 100 rifles and 12 boxes of ammunition, and the following morning the legion was officially constituted.

Throughout the period of unification, in addition to their participation in numerous battles, the legion was used to suppress brigandage and to provide public security alongside the authorities.

On 21 September the legion, under Csudafy, fought unsuccessfully alongside the Garibaldian Column against the Bourbon Army, which conquered and set fire to Caiazzo.

The success of the Garibaldian troops in liberating Piedimonte was evidenced in the battle, where 191 volunteers of the Matese Legion participated, under the command of Major Guadagni.

On 3 March 1861, the Matese Legion reunited for the last time in Caserta in front of the Mayor Giuliano Amato Giaquinto, in order to return their weapons.

[7] The Matese Legion was founded by Beniamino Caso and Bonaventura Campagnano, who were in charge of recruiting all the volunteers in the district and in other localities within the province.

They stage events in cities across Italy, particularly in Rome, in order to share the history and spread awareness and knowledge the Matese Legion.
