These men gained great influence over Chu, and persuaded him to give up attacking rich individuals, and instead to establish an assured control over large parts of the country. He would then, they pointed out, be permanently enriched, while otherwise he would only be in funds at the moment of the plundering of a town. They set before him strategic plans with that aim. Through their counsel Chu changed from the leader of a popular rising into a fighter against the dynasty. Of all the peasant leaders he was now the only one pursuing a definite aim. He marched first against Nanking, the great city of central China, and captured it with ease. He then crossed the Yangtze, and conquered the rich provinces of the south-east. He was a rebel who no longer slaughtered the rich or plundered the towns, and the whole of the gentry with all their followers came over to him en masse. The armies of volunteers went over to Chu, and the whole edifice of the dynasty collapsed.
The years 1355-1368 were full of small battles. After his conquest of the whole of the south, Chu went north. In 1368 his generals captured Peking almost without a blow. The Mongol ruler fled on horseback with his immediate entourage into the north of China, and soon after into Mongolia. The Mongol dynasty had been brought down, almost without resistance. The Mongols in the isolated garrisons marched northward wherever they could. A few surrendered to the Chinese and were used in southern China as professional soldiers, though they were always regarded with suspicion. The only serious resistance offered came from the regions in which other Chinese popular leaders had established themselves, especially the remote provinces in the west and south-west, which had a different social structure and had been relatively little affected by the Mongol regime.
