The Italians crossed the borders of Congress Poland on May the 3rd near Krzeszowice and joined a group of Polish insurgents led by colonel Józef Miniewski.
That day the unit's first battle in Poland occurred at Podłęże where they defeated a Russian force.
A number of Garibaldians were taken prisoner and deported to Siberia after the battle while others managed to escape the battlefield and returned to Italy.
[4] While the military contribution of the Garibaldi's Legion was minimal, it was vividly remembered as a symbol of foreign support for the Poles and their cause.
A number of streets, schools, and other monuments/locations in many cities in Poland are named in honor of Nullo or his unit.
