A quick flip through December 8th sources reveals he used Senshi Sosho a lot, plus Izawa and a bunch of personal interviews Bartsch did in the 80's Much of the IJA stuff seems to come from Izawa.
December 8th is really good for just explaining how unprepared the AAF was. .50 cals for the P-40s still in cosmoline, because they didn't have much ammo for them, so the pilots training on the planes were unfamiliar with the weight when the time came and they actually put them in.
The first volume had a fair amount of overlap with William Bartsch's Philippines books, but they pretty much agreed, however that was IJN and particularly Tainan Ku, which seems to be the one IJN unit english sources get right, for the most part.
I thought the tracking of the prototype Ki-44 unit was particularly well done.
How well is Christopher Shores' "Air War for Burma" sourced on the IJA side? The first two Bloody Shambles books seemed well documented, but I always have to save up for those purchases so I haven't read the third.
Current cheapest price I can find is somewhere north of $150, so I'll be holding off. Someone on ebay has a signed copy priced at $485, so congrats on that?
So. Many. Typos. Espiritu Sancto? [sic]. Multiple times.
I quite enjoyed Browned Off and Bloody-Minded, which with Raising Churchill's Army has given my American mind the most complete picture of the British Army I've found to date. I still don't get (and probably never will) the whole batman thing, 'tho.
