Regardless of who was responsible for the decision, the Guangdong Committee began to prepare its uprising in earnest from 27 November. A Revolutionary Military Council was appointed with Ye Ting as commander-in-chief and Zhang Tailei as chairman.

According to CPC leader Zhang Guotao, Neumann came to wield great influence on the committee and took a leading role in the rebellion; others believe that he was just a messenger for Stalin. The core fighting force of the rebellion consisted of an "ad-hoc" "Red Guard" formed by 2,000 armed workers, and a communist-infiltrated cadet regiment of 1,200 soldiers.
