'The Defence and Fall of Greece 1940-41' by John Carr, primarily covers the Italian invasion of Greece that started in October 1940.
It plugs an important gap, in the English language at least, in the history of the Balkans in World War 2. Mario Cervi's excellent 'Hollow Legions' looks at the campaign from the Italian side, albeit critically. I used his work, together with the memoirs of British participants, in my own article on the campaign after I visited some of the battlefields and the museum at Kalpaki. This really is one battlefield you need to visit to understand what happened.
Mussolini's bungled campaign was far from the quick campaign he planned. Badly led Italian divisions ground to a halt against determined Greek resistance, in terrain that levelled the technical inferiority of the Greek forces. A Greek counterattack forced the Italians back into the Albanian mountains and a winter campaign that took a terrible toll on both armies. By the Spring, Hitler was forced to bale out his allies with a blitzkrieg in the Balkans that rolled up the exhausted Greek armed forces and their recently arrived British and Commonwealth allies.
The author has drawn heavily on Greek sources for this book, both from the diaries of front line soldiers as well as the war diaries of Prince Peter, who served on the General Staff and as liaison with the British. It covers the war on the ground as well as in the air and at sea. It is very well written, a real page turner. It could have done with more maps and illustrations, but that is a small criticism for what is an excellent history.
Reading the book inspired me to dust down my 15mm Flames of War armies for the campaign. On this occasion the Italians broke through.
Here is the battlefield with the Italians storming across a stream from the left.
Finally a link to my 25mm figures for the campaign. You can tell I'm really into this period!
