Chiang's marriage, which had been made Chinese-fashion in his late boyhood, had given him posterity--a son, now the pro-Communist, Soviet-trained Major-General Chiang Ching-kuo--but little companionship. His wife and son remained most of the time at his native home, whence he returned to see them and his mother, at Fenghua in Chekiang. Social contacts, acquaintance with capitalism, looseness of family connections, spasmodic work for the Revolution, and some military work--this, combined with the making and the losing of a fortune, fill the early maturity of Chiang. He appeared upon the national and the world scene by his selection in 1923 to go to Moscow under the terms of the Nationalist-Soviet understanding, there to receive military training. He had definitely cast in his lot with Sun Yat-sen, making soldiery his vocation, and the selection implied that Sun began to see in him a military aide, to replace Huang Hsing of the first revolution. Chiang spent four months in the Soviet Union. The Communists, whom he was to fight six years later, showed him their combination of political and military warfare applied in Trotsky's Red Army. Chiang, already the beneficiary of Japanese training, had found Japanese military science dependent upon the framework of a stable constitutional system. In China his earlier training had been superior to its environment and did not have the practical utility of five years' banditry. Chiang, professional by spirit, restless under the drive of conscience and ambition, now found in Moscow the intermediate steps between modern warfare and government-building. He found that an army, from being the tool of pre-existing order, could become the spearhead of an accompanying order. Returning to China via the Trans-Siberian Railroad, he met General Galens (Vassili Bluecher), later his chief Soviet military aide at Canton. In Canton, the first military creation on Soviet models was the Whampoa (_Huangpu_) Academy. Decreed by Sun Yat-sen, who made Chiang chief, the Academy had Soviet advisers, eager to instill revolutionary and civil-war techniques. Chiang began the development of a modern army, and the real accretion of his own power. Even before he commanded full armies, Chiang used his cadets to good purpose in actual combat.
