The CAP prevented any merchant ship losses prior to the carriers having to turn back due to the proximity of Sicily. The battle was decided by the Sea Hurricanes because had Axis AF strike aircraft sank even one or two merchant ships prior to the carriers turning back then Malta might have been starved into submission.
Doesn't sound very decisive to me. How many a/c did those Hurris shoot down or deter before exiting the battle? How many Axis planes were able to attack due to their short range?
