The more than 8.500 page views in barely one month give me enthusiasm to explain further my AU described here. Ships, military and other equiipmnet, all that can be drawn. My aim, however, and as already said, is to explain the context I'd like to have seen Germany, my family's land of origin, though not mine, take from 1935 on. I think this explains somewhat the big number of pageviews.
Continuing: By 1939, Germany had made several important agreements, mainly of trade (genre of the EFTA put together after WW II in the real world), since the civil members of the government, first of all Konrad Adenauer, at the time minster of the internal affairs (Innenminister) came to the conclusion that the only way to end the misery of the jobless society of those times was to implement industrial growth. One of Adenauer's main key personality of his private inner circle was an economicist of 42 years of age, Ludwig Ehrhardt, a brilliant man having made his Ph.D. with a dissertation about modern economics after the worldwide crash of 1929, following the ideas of people like Frank Oppenheimer, Carl Friedrich Goerdeler and Otto Ohlendorf, now deputy secretary of state in the Reichsministerium für Wirtschaft (Ministry of Commerce). And contrary to the Lebensraum fixed idea of the nazis (land to live) suggesting Germany was too small for its population, thus justifying the anexation of Austria and Chekoslovakia, a designated goal for Hitler, Adenauer and his inner circle followed the idea of state sponsored investments and free trade among similar minded states, arguing that trade of commercial and industrial goods would by itself create jobs, while putting money into circulation in the market (a combined social-liberal political line). And without a strong Wirtschaft ("economics, stupid!"...) no strong state could ever be financed for all its expenses. Including here its armed forces. This is the link of the German Kriegsmarine with the general economy of Germany and the reason for my somewhat detailed information about a Germany I'd like to have been, in those days....
Continuing the social and political side: By 1939 the German government had felt the necessity to implement sort of a "soft dictatorship". The German government and part of the German military had seen in Spain, through the involvement of the "Legion Condor", what a bloody civil war could lead to. The inner German events which took place in 1935, after the coup against the nazis, were not at all comparable to what the Germans witnessed in Spain. This led to von Witzleben, the actual German chancellor, and the military top brass, to an unofficial deal to not let happen at all cost that such events would ever take place in Germany. The influence of the social party and also of the communists was still being felt, and after the fall of Reinhard Heydrich, the bloody chief of the SD (secret information service) and the major rival of Admiral Canaris of the Abwehr (counter espionnage), these two sides began to feel sort of a liberty of movements, mainly on the worker's union side, trying to repeat the "status quo" existing during the Weimar Republik. These events had led to chancellor von Witzleben making sort of an "institucional revolution", with the backing of the military, taking in late 1935 the Reichstag (German parliament) and imposing "martial law" for six weeks, during which all political activities were suspended. During this period, the side of von Witzleben formed a new party, the Neue Deutsche Sozial-Demokratische Partei", in short DSP ("new German social democratic party"), giving the maximum attention possible to the social welfare without, however, taking any step to frighten the middle and upper classes, regarded as essential to make Germany a leading industrial nation, to compete with the UK, France and the USA on a peaceful way. To every politician trying to argue against, von Witzleben replied in his firm way of speaking: "We lost WWI because of the lack of competivity on the industrial side, all other arguments are nonsense! And my government won't let the communist virus infect our country, thus we have to ban also de socialist movements, which are the ice breakers to the communists! Social welfare is one thing, socialism another completely different and we've seen to which counter reaction that leads to! Period!"
This is why the new German government was quick to sign the A.G.N.A. and succesively trade and cooperation agreements with several countries of Middle and Northern Europe. With Sweden and Finland cooperation agreements were made regarding mainly naval and aviation (Sweden) and infantry and aviation equipment (Finland), as well as supplying refined fuels for their respective armed forces. The same applied also to Norway, a country to which several transport floatplanes were sold, as well as fuels. With Austria and Checoslovakia industry agreements were on top of the list, mainly guns and military vehicles from the former and cooperation on airplane design and production with the latter.
Two countries asked Berlin for special agreements, in respect of problems both felt on their security levels: The Netherlands which saw their East India territories more and more threatened by Japan and Finland, which felt a growing pressure from the part of the Soviet Union. With both nations Berlin signed secret agreements regarding assistance should any threat get real on this level. Especially The Netherlands got assurance of naval assistance since Germany was already a client of the Dutch regarding oil products coming from Sumatra and Borneo. The interest in maintaining a "statu quo" in this respect was on both sides. Finland had another weight, since Berlin knew that Moscow looked very intensively not only to Finland but also to the three Baltic countries between Finland and East Prussia. This threat seemed even more important to Berlin for obvious reasons. Moscow could not forget nor accept the defeat of its Spanish friends at the hands of Franco's troops heavily assisted by Germany's "Legion Condor", nor the total banning of the communist party in Germany. Berlin was fully aware that sooner or later some event would take place on the part of the soviets and began in the spring of 1939 to make contingency plans which obviously included the "Kriegsmarine".
PS: Thanks to all who have so far taken their time to have a view on these pages. I'm trying to give you something interesting and plausible. It depends on your interest if and how far I continue with this account. What I have written already for myself is a German involvement in the "Winter War", assisting Finland, on one side, and on the other side Germany assisting The Netherlands in securing their overseas possessions in East India and the consequences that had. Obviously involving the "Kriegsmarine".
