I concur with the first reveiw that the Mr. Goldman's work illuminates the diplomatic nuances of the Nomonhan operation very well, and also that military operations are not covered in such great detail as might be desirable. However, I must add, his coverage of the miltary side, while brief, is also concise with so much being said in few words. Above all, it holds the virtue of clarity. The maps are good and the text offers the clearest outline of the battle I have read.
The account of Nomonhan by Alvin Coox is far more detailed, but includes irrelvent minutia such as inconsequential distant sightings of Soviet troops by Japanese obervers and the minutest details of flag burning ceremonies and body recovery operations. Such infomation encumbers the forrest with so many trees that the larger tactical and operational pictures are often obscured. As noted, Coox's work is mostly from the Japanese point of view, but many of the tactical operations covered are, fortunately, rich in detail.
John Colvin and Douglas Varner offer very good summaries of Nomonhan, similar to Goldman's in size, with a similarly fair balance betweeen the Soviet and Japanese perspectives. They are slightly more detailed, but less concise and not so clearly organized. Goldman offers far more clarity, coherence and logical sequencing in presenting the campaign. Experts should appreciate his summary as a quick review. Novices to the topic, are unlikely to find a better introduction.
