I’ve interest and have a suitable British force but yet to put together Italians. Interestingly, while many consider it a sideshow it was actually a campaign of critical grand strategic importance.
Whoever controls the Horn of Africa controls access to the Red Sea, who then controls access to the Suez Canal, so not an insignificant matter. While it remained a ‘war zone’ the neutral Americans would not send any shipping via the Pacific to the Middle East, another reason to resolve control of the area. At the time Britain’s main threat for control of the Mediterranean were the Italians and so anything that destabilised and threatened the Italian empire was good for the war effort. Taking out an Italian territory that threatened Egypt from the south and British African possessions like Kenya from the north was also important so that all effort could be focused on winning the war in North Africa.
I think it appears a sideshow because in 1940 events like the fall of France and the Battle of Britain tended to over shadow a war in a distant land when the home islands were under threat. Yet in a grand strategic sense it was a key event in the downfall of Italy and wrestling back control of the Mediterranean from the North African coast.
If that’s the big picture then the small picture is just as interesting with a fascinating mix of units, terrain and equipment, lots for a wargamer and miniature painter to like.
