After successfully besieging the adjacent regions of Ruijin, the capital of the Jiangxi Soviet, and occupying most of Jiangxi Soviet itself, Chiang was confident that he would finish off the communists in a final decisive strike. In late September 1934, Chiang distributed his top secret plan named "Iron Bucket Plan" to everyone in his general headquarter at Lushan (the alternative summer site to Nanchang), which detailed the final push to totally annihilate the communist forces. The plan was to build 30 blockade lines supported by 30 barbed wire fences, most of them electric, in the region 150 km around Ruijin, to starve the communists.
