This book by Prof. Stuart D. Goldman describes this relatively unknown incident called the Nomonhan Incident (or the Battle of Khalkhin Gol). But more than just describing the incident, the author put forth an important thesis: this battle, while relative small compared to others yet to come, and confined to a tiny, obscure area in the plains of faraway Mongolia, had a profound impact on how WW2 eventually developed. In particular it was because of this battle that Japan became convinced that they should avoid another conflict with Soviet Union, giving more force to those who argued that they should go down south for the resources that they need. And to prevent the US from intervening, they had to destroy the US fleet in Pearl Harbor, the rest, we all know.
The author developed his argument by taking the reader down two tracks. The first being the history associated with the Kwantung Army leading to the border disputes with the Russians. The second is the global context, setting out what was happening in other parts of the world (especially in Europe) and situating this incident within that larger context. With these in place, the author then explained first why the conflict took place and then how it led to subsequent developments in WW2.
Following the first track, besides the history related to the formation of the Kwantung Army, which was informative in itself, the author took pains to explain the concept of Gekokujo (下克上, literally "lower level overcoming upper level") which has been associated with the Japanese Army (less the Navy) and most frequently with the Kwantung Army. This is a strange concept that, as far as I know, is only present in the Japanese Army where mid-ranking officers either manipulated or openly defied their senior officers' commands to do what they wanted. The further away they were from the central command in Tokyo, the worse the transgressions. The author showed with many examples how this manifested itself in the Kwantung Army.
Further to their tendency to exhibit Gekokujo, they also had a sense of invulnerability which was heightened by their perception that the Russians were weak. And at one point indeed they appeared to be (pg 17). This together with the ineffective commands from Tokyo that the Kwantung Army commanders were determined to ignore, and the purposely vague border protection policies issued by the Kwantung Army commanders (pg 89) made for an inevitable showdown with the Russians - the question is what would the Russians do?
By way of introducing the Changkufeng Incident a year before the Nomonhan Incident, the author explained to the readers that the Russians probably felt that the time had come to put their foot down in their dealings with the Japanese, especially with the Kwantung Army. When the Japanese acted against the Mongolians (the allies of the Russians) in Nomonhan in 1939, the Russians decided that they had to teach the Japanese a lesson. The story then went on to describe in good details about the campaigns that took place in that period of four months, at an exciting pace for a scholarly work. More importantly, throughout the description, the author kept an eye on Stalin's responses and decisions, which in contrast to the Japanese's perspective, was wide in its geopolitical considerations. And who can blame him, for the Soviet Union spanned both Europe and Asia and could find herself potentially fighting a two-front war which Stalin was determined to avoid.
The Japanese had no such worries, although they should. While arguably in the same theatre, 1939 was also when Japan was beginning to be caught in the quagmire in China. So while the Tokyo wanted to play down the Nomonhan Incident, the Kwantung Army would have none of it. But in an almost ridiculous fashion, the Kwantung Army could be so compelling that even Tokyo went along with them despite an Imperial Order.
General Nakajima, deputy chief of AGS (Army General Staff), flew to Hsinking with Imperial Order 343, commanding Kwantung Army to hold its position near the disputed frontier with "minimal strength" to ensure a quick end to hostilities and a prompt diplomatic settlement. But in meeting with Nakajima, the KwAHQ (Kwantung Army HQ) Staff, led by the Operations Sections, clung passionately to its convictions. Incredibly, Nakajima was won over by the staff's fervent spirit and gave verbal approval for Kwantung Army's general offensive to begin on September 10. (pg 150)And so the slaughter on both sides started.
The author paid a reasonable attention to the Russian forces as well, never hiding the fact that their loses were equally appalling and that the incident, while celebrated for the bloody nose it gave to the Japanese, did not come at a small price for the Russians. Particularly enjoyable was to read about Marshall Zhukov who was given the first significant command of his career, coming in the wake of Stalin's purge of his more experienced commanders.
For a book that is no more than 180 pages, persuading readers about his thesis is an ambitious feat for the author. But he succeeded admirably. This is not to say that other scholars could not find reasons to disagree with him as he himself admitted in the Preface but at least in terms of academic rigor and logic, his case was compelling. Although many pieces of his evidence were circumstantial, the use of the dates of various events on the side of the Russians seemed to suggest that Russian reactions to the geopolitical scenario in relation to Germany, Japan and subsequently to Poland hinged much on the Nomonhan Incident and its conclusion.
On the Japanese side according to Colonel Hayashi Saburo, one of the General Staff officers, there was general recognition that they should leave Russia alone and from then on, and should only make their move south (into Southeast Asia). This compares well with what was said by Japanese Scholar Kazutoshi Handō (半藤一利) in Showa Shi (昭和史), where both Masanobu Tsuji and Takushiro Hattori were said to have decided that "in future, go south." And going south meant going after Pearl Harbor too.
This book is surely a good place to start for those of us wanting to get an introduction to the Nomonhan Incident. But to say that it is but an introductory book is unfair because it comes with a huge amount of information, all organised logically, and presented persuasively.
