Nonetheless, the Cuno strikes nurtured, in Moscow, the hope of a German revolution. There had been clashes with police in several cities and dozens of workers had been killed. Leon Trotsky and other Influential members of the Soviet Politburo and the Comintern believed Germany was ready for revolution, but Heinrich Brandler, the head of the KPD, felt the timing was premature. Despite Brandler's misgivings, on 23 August 1923, the Soviet Politburo adopted a plan for a "German October", but the attempted coup was cancelled at the last minute. Word of the cancellation did not reach Hamburg in time (or was possibly ignored by the local KPD leadership) and the local insurrection took place, as planned.
