1. The British had an easier convoy problem. Those were only Germans after all. The Italians were fighting the British, an enemy with a far bigger air force, a much more technologically advanced navy, and with better infrastructure and logistics assets in the Med.Nice map.
Still not entirely sure how this reinforces your opinion that Italy were better than the British at Convoying
Maybe the light is different that side of the looking glass eh?
2. Why are the Italians better at whack-a-sub? They did not have ASDIC and their other ASW gear is decidedly (on paper) inferior.
3. In the clash of the light forces, the RN and the RM at best are honors even.
4. Getting 90% through with the Germans as your inept allies blabbing your secrets and as tyros at sea and in the face of enemy air superiority has got to count for something?
Just for starters.
BTW, that map is how the Americans saw the European War. Blue is SLOCs, Green is land actions. Lavender is Soviet LLOCs and RED is of course the anvil moving west to meet the Wallie hammer moving east.
