Guido Keller formed a military corps from volunteers who has made their way to Fiume from Italy and had camped out in the city's shipyards.
Keller experimented with his ideas of a new military order, making them march bare-chested and singing through the streets of the city.
[2] This corps took the name La Disperata meaning “(the guard) of desperate men”, and became famous among the arditi and fascists for their fearlessness and the charisma of its leaders.
