On the 9th February 1941, Churchill ordered troops to halt their highly successful offensive against the Italian's in North Africa (Operation Compass) in order to divert British forces in an ultimately failed attempt to save Greece from Axis occupation.
Operation Compass was an astounding success. From December 1940 to February 1941, a force of 36,000 British and Commonwealth soldiers chased an Italian Army of 150,000 out of Western Egypt and across Eastern Libya. In the process they captured 115,000 Italian soldiers, killed 3,000, destroyed 400 tanks, 1,300 artillery pieces and 1,250 aircraft.
Bear in mind that in reality, the war dragged on in North Africa until 1943, ultimately costing the Allies some 238,500 casualties (And the Axis some 620,000-900,000 casualties including POW's along with 8,000 aircraft, 6,200 artillery pieces and 2,500 tanks)
So my question is, what if Britain hadn't redirected its focus from North Africa for Greece and instead pressed on the attack?
Is it possible that the Italians could have been driven from North Africa as early as late 1941 before German forces even had a chance to arrive?
And with that in mind, could we have seen a British invasion of Sicily with limited US support occur as early as 1942? Or did Britain lack those capabilities? Might an early victory in North Africa have given more weight to Churchill's 'soft underbelly' strategy?
And on the issue of Greece, i have heard it mentioned that the British intervention delayed German plans for Operation Barbarossa for a vital month. Is there any weight to these claims? To be honest I am quite unconvinced.
