I watched a WW2 documentary about this region last week on tv and that the Australian forces had a huge
battle up on those hills. A real massacre!
If it was not for them stopping the Japanese army, they would have invaded India.
In the documentary they did not mention any air force helping in this battle, just ground troops fighting
to the death for almost a month.
You must be speaking of the Battles at Imphal and Kohima in India. In China, the Chinese Army and US air forces fought against the Japanese. Until 1944 the only action in this region of china was between the air forces, bombings, interceptions, etc.
In 1944 the Japanese launched their largest ground operation of the war - Ichi-Go.
http://en.wikipedia.org/wiki/Operation_Ichi-GoThere were major battles/sieges at Changsha and Hengyang and they captured lots of territory including the US bases at Hengyang, Lingling, and Kweilin. They were finally stopped at the Battle of Chikiang (Zhijiang).
The books "Sharks Over China" and "Wing to Wing" are very informative about the war in this part of China.
Also, "Chennault's Forgotten Warriors" - about 308th Bomb Group (B-24s).
And any other book about the Flying Tigers.
