This only works if there are only Italian aricraft scrambling. I usually use two fighters from the United Kingdom terirtory, and the fighter from Malta-the fighter from Girbraltar should be used along with the cruiser off of Girbraltar (it takes three submarines to have more than an 80% chance to kill it, my normal standard to win a battle, so the submarines are usually used for easier prey in the north, especially if Germany attacks the Soviet Union in the first turn, which will nessecitate one submarine in sea zone 125) to destroy the Italian navy off of Malta. If a German aircraft lands in Southern Italy, I usually will call of the attack, as there is a less than 80% chance to win. All of this assumes Germany invades the Soviet Union in the first turn.
