The agreement did not last long, though, for on December 29, 1918, Haase, Wilhelm Dittmann and Emil Barth left the council again to protest the SPD's actions during the soldier mutiny in Berlin on November 23, 1918.
Enigheden varede dog kun kort, for allerede 29. december 1918 forlod Haase sammen med Wilhelm Dittmann og Emil Barth rådet for at protestere mod SPD's aktioner under soldatermytteriet i Berlin 23. november.
