Savielly Tartakower (Poland), and Albert Becker (Germany), plus the president of the Argentine Chess Federation, Augusto de Muro, decided to go on with the Olympiad. Alekhine won the individual silver medal (nine wins, no losses, seven draws), behind Capablanca (only results from finals A and B—separately for both sections—counted for best individual scores). Shortly after the Olympiad, Alekhine swept tournaments in Montevideo (7/7) and Caracas (10/10). At the end of August 1939, both Alekhine and Capablanca wrote to Augusto de Muro regarding a possible world championship rematch. Whereas the former spoke of a rematch as a virtual certainty, even stating that the Cuban was remaining in Buenos Aires until it came about, the latter referred at length to the financial burden in the aftermath of the Olympiad. Supported by Latin-American financial pledges, José R. Capablanca challenged Alexander Alekhine to a world title match in November. Tentative plans—not, however, backed by a deposit of the required purse ($10,000 in gold)—led to a virtual agreement to play at Buenos Aires, Argentina, beginning on April 14, 1940. World War II (1939–1945) Unlike many participants in the 1939 Chess Olympiad, Alekhine returned to Europe in January 1940. After a short stay in Portugal, he enlisted in the French army as a sanitation officer. After the fall of France (June 1940), he fled to Marseille. Alekhine tried to go to America by traveling to Lisbon and applying for an American visa. In October 1940, he sought permission to enter Cuba, promising to play a match with Capablanca. This request was denied. Relationship with Nazi Germany Chess historians have had a significant interest in Alekhine's affiliation with Nazi Germany. Of ongoing speculation among historians specialising in mid-20th century European chess is whether or not Alkehine was the author of numerous antisemitic pieces of propaganda published in relevant partisan materials at the time. While an analysis of writing styles is perceived to provide evidence supporting the theory Alekhine willingly worked as a propagandist in a non-coercive fashion, Alkehine himself denied this in written letters. By some accounts, to protect his wife, Grace, and her French assets (a castle at Saint Aubin-le-Cauf, near Dieppe, which the Nazis looted), he agreed to cooperate with the Nazis. Alekhine took part in chess tournaments in Munich, Salzburg, Kraków/Warsaw, and Prague, organised by Ehrhardt Post, the chief executive of the Nazi-controlled Grossdeutscher Schachbund ("Greater Germany Chess Federation")—Keres, Bogoljubov, Gösta Stoltz, and several
