Danzig and Memel were to be ceded to the Allies, their fate to be subsequently decided. A portion of Silesia was to be ceded to Czechoslovakia. Also, apart from the actual cessions of territory, the treaty arranged that plebiscites should be held in certain areas to decide the destinies of the districts concerned. Certain districts of East Prussia and West Prussia were to poll to decide whether they should belong to Germany or to Poland. A third portion of Silesia, which was in dispute between Germany and Poland, was to exercise the right of self-determination. The small districts of Eupen and Malmedy were to decide whether they would belong to Belgium or to Germany. The middle and southern districts of the province of Schleswig, which had been annexed to Prussia in 1866, were to decide their own destinies. Finally, the coal-producing valley of the Saarland, which had been provisionally separated from Germany, was to be the subject of a referendum after the lapse of fifteen years.
