What happened September 1927 AD in China

On August 4, the main forces of the Red Army left Nanchang and headed southwards for an assault on Guangdong. Nationalist forces quickly reoccupied Nanchang while the remaining members of the CPC in Nanchang went into hiding.

Mao was appointed commander-in-chief of the Red Army and led four regiments against Changsha in the Autumn Harvest Uprising, in the hope of sparking peasant uprisings across Hunan. On the eve of the attack, Mao composed a poem—the earliest of his to survive—titled "Changsha". His plan was to attack the KMT-held city from three directions on September 9, but the Fourth Regiment deserted to the KMT cause, attacking the Third Regiment. Mao's army made it to Changsha, but could not take it; by September 15, he accepted defeat and with 1000 survivors marched east to the Jinggang Mountains of Jiangxi.
