Airman
I read the question as which AIR BATTLE (no sea or ground forces involved in the actual fighting other than AAA) and we all seem to be talking about extended CAMPAIGNS. Would not the LW driving the 8th AF from the daylight skys over Germany count as winning a BATTLE although eventualy losing the CAMPAIGN? So, I would put Midway up there as winning a battle, the BoB and Malta had its ups and downs along with most extended periods of warfare. Anyway, just my take on the question.
