[Hobilar]

By 1945 the Allied Armies in Italy consisted of Regiments drawn from:

Brazil
India
Italy
Nepal
New Zealand
Palestine
Poland
South Africa
United Kingdom
United States of America
France
Basuto
Bechuana
Swazi
Seychelles
Rodriquez
Various Caribbean Islands
Cyprus
Greece
Syro-Lebanan
Yugoslavia
Belgium
Goumiers (from North Africa)

The United States had one Division comprised entirely of Negro-Americans, though Clark was rather scathing about their fighting qualities. They also had a Regiment comprised of Japanese-Americans.

The Italians were considered a dour and unhappy lot. General McCreery had to forbid one Italian General from attending his conferences because the Italian Commander depressed the other Commanders so.

The Greeks too came in for some criticism from McCreery as they would dutifully listen in to orders- and then go off an do exactly what they pleased.

Credit must be given to the Staff Officers who had the unenviable task of controlling such a combination of different nationalities and cultures. When you consider that there were among others Sikhs, Japanese-Americans, Gurkhas, Irish, Maoris, and Jews, then surely this must be unique in history in being the only time that so many different cultures and religious persuasions have ever fought so selflessly together in a common cause.

Note: I have not included the Canadians, who had been in Italy earlier in the campaign as I have found no source that will confirm that Canadian front line units were still in Italy in 1945 (the bulk of their forces having gone to the Northern Europe theatre). If anyone has any evidence to the contrary I would be pleased to hear it
