Chiang's fifth campaign, launched in September 1933, was much more difficult to contain. Chiang's new use of "blockhouse tactics" and larger numbers of troops allowed his army to advance steadily into Communist territory, and they succeeded in seizing several major Communist strongholds. Bo Gu and Otto Braun adopted orthodox tactics to respond to Chiang, and Zhou, although personally opposed to them, directed these. Following their subsequent defeat, he and other military leaders were blamed.
