Author: Col. Prof. Dimitar Nedialkov, PhD Publisher: Crecy Publisher Unlimited Length: 215 pages including index Nedialkov is a Bulgarian pilot and scholar, who delves into the air war in the Nomonhan/Khalkin-Gol battle in the Summer of 1939. He starts us off with the Japanese air buildup and the token air force the Soviets have in Mongolia. We're then given the account of the first blows Japan strikes at the Soviets airfields. The Russians respond by bring in their aces from the Spanish Civil War and their clandestine China support. We are told about the Soviet buildup and first battles, where the Japanese planes, such as the Ki-27 fighter, outperform the I-16 fighter, and the Russians struggle to bring more numbers in to gain control. The climax of that struggle is in July and August, when the "quantity is their quality" of the Russians manages to smother the Japanese air component and go on the offensive. Finally the great air battle over the Khalkin-Gol area is waged, with pilots from both sides landing to pick up their shot down comrades, grounded Japanese pilots using their swords on the Russians, and many aces are created on both sides. Nedialkov goes on to give us the list of planes used by both sides, and the list of aces for the Soviets and Japanese. This is a scholarly work, in which Nedialkov gives us the list of kill claims for both sides, and the three or four different versions of them, thanks to over claims by both sides and propaganda efforts. He also gives us the performance of the many planes and tables of kill ratios. So people looking for personal stories will be disappointed. The translation is also a little iffy at times as far as grammar is concerned. Plus his bibliography is mostly in Cyrillic. Overall, this would be a good work for the person interested in finding details about the air war in this little-known but important campaign.
