A Communist leader addressing Long March survivors.After Chiang Kai-shek had foiled the coup to oust him launched by Feng Yü-hsiang, Yen Hsi-shan, and Wang Ching-wei (1929-30), he immediately turned his attention to rooting out the remaining pockets of Communist activity. The first two campaigns failed and the third was aborted due to the Mukden Incident. The fourth campaign (1932-1933) achieved some early successes, but Chiang’s armies were badly mauled when they tried to penetrate into the heart of Mao’s Soviet Chinese Republic. Finally in late 1933 Chiang launched a fifth campaign orchestrated by his German advisors that involved the systematic encirclement of the Jiangxi Soviet region with fortified blockhouses. By the fall of 1934, the Communists faced the possibility of total annihilation. It seemed that the time was now ripe to finish off the CPC, then turn against the remaining warlords, before finally retaking Manchuria from the Japanese.
In October of 1934, the Communists decided to make a massive military retreat to the west to escape the ensuing KMT forces. It was under this yearlong, 6000 km retreat, called the Long March, which ended when the Communists reached the interior of Shaanxi, that Mao Zedong emerged as the top Communist leader. Along the way, the Communist Army confiscated property and weapons from local warlords and landlords, while recruiting peasants and the poor, solidifying its appeal to the masses.
