While there are a few English-language sources covering the British in Italy, there doesn't seem to be any dedicated to the French in Italy, or the Italians in France.
Can anyone recommend an English-language source that covers the Italian units sent to France?
Or conversely, an English-language source on French units in Italy?
Or barring that, books in Italian or French? (I studied French for a few years but that was a long time ago. So, effectively, I read neither. I might be able to sus out meaning with a dictionary if I have to).
