What did hitler do when he saw the march on rome?

On March 23, 1919, but four months after the armistice that ended the Great War—100 young toughs, ex-Italian Army war veterans, former socialist politicians, and newspapermen met in Milan’s Piazza San Sepolchro in industrial northern Italy to form a new political party. By the fall of 1922, the Fascists numbered over 300,000 members.

Dissatisfied with the territorial gains gleaned from Liberal Italy’s participation in the war on the Allied side during 1915-1918, these angry young men, typified by 39-year-old Benito Mussolini, formed the Fasci di Combattimento, which their leader [Il Duce] himself defined as “The Bundles of Battle.” He was referring to the ancient Roman Imperial symbol of an axe surrounded by rods bound together, as their past and present symbol of authority and power.
