The vote in the first zone, held February 10, 1920, resulted in a decisive Danish majority of three to one, and led to occupation by Denmark, as the treaty had provided. Feeling ran high in the second zone, where the German government sought to influence the decision by threats in the Reichstag; the struggle centred around Flensburg, certain in either event to be a frontier town now that the third zone had been eliminated. The plebiscite, held March 14, resulted decisively for Germany, the vote in Flensburg being overwhelming and only a few scattered villages on the islands voting for Denmark. The result failed to satisfy either party entirely, a large Danish group still wanting Flensburg, while in the first zone the Germans wished to recover Tönder, where the voting had favored Germany. Indeed it remains to be seen whether German hopes of recovery will be limited to Tönder. One question of which Denmark and the Schleswigers showed great desire to keep clear was the Kiel Canal. Even the widest limit of evacuation proposed carefully left a belt of Schleswig territory between its southern border and the canal, lest what was fundamentally a question of popular rights might become complicated with a wholly distinct international problem. Only in case of the internationalization of the canal would its fate have reacted on the Schleswig problem by leaving an isolated strip of German territory to the north which might then have been separated from Germany and attached to the adjacent Danish territory. Whatever might have been said for the internationalization of this great waterway, the question was not seriously considered at the Conference. The parallel to Suez and Panama was too close! The treaty leaves the canal under German control, but provides that it shall be open on terms of entire equality to the vessels of commerce and of war of all nations at peace with Germany.[9] The island of Heligoland, which England had seized from Denmark in 1807 and ceded to Germany in exchange for Zanzibar in 1890, is not restored to either of its former owners. Instead it is stipulated that all fortifications and harbor works there shall be destroyed by German labor and at Germany’s expense, and that no similar works shall be constructed in the future.[10] Immunity for the future might do something to offset the great price which England had paid for Zanzibar throughout the World War.
