The most famous action of the Bersaglieri occurred on 20 September 1870, when the 12th Bersaglieri battalion stormed Rome through a breach created by Italian artillery in the Aurelian Walls near Porta Pia leading to the capture of Rome and end of the temporal power of the Pope, thus completing the unification of Italy. A monument was erected in 1932 in front of Porta Pia to commemorate the event at the same time as the National Museum of the Bersaglieri corps was moved to Porta Pia, where it resides still today.
