Answer: Yongle proved extremely ambitious. He temporarily conquered Vietnam and tried to overpower Japan. He built a new imperial capital in Beijing, including the Forbidden City, and extended the Great Wall. Since he was determined to control trading in the Indian Ocean, one of his first acts was to commission the construction of 3,500 ships, with Zheng He supervising the construction and then commanding the fleet.
Some of these ships were the largest marine craft the world had ever known. Zheng He’s nine-masted flagship measured about 400 feet long; for comparison, Christopher Columbus’s Santa Maria measured just 85 feet. On the first voyage, from 1405 to 1407, 62 nine-masted “treasure ships” led the way, followed by almost 200 other ships of various sizes, carrying personnel, horses, grain, and 28,000 armed troops.
Historians were skeptical of accounts describing the size of these ships until, in 1962, workers on the Yangtze riverfront found a buried wooden timber 36 feet long (originally a steering post) beside a massive rudder. It was the right size to have been able to steer a ship of 540 to 600 feet in length, and the right age — dated at 600 years old — to be from one of Zheng He’s ships.

Zheng He’s initial trip took him from the South China Sea through the Indian Ocean to Calicut, India, and back. The emperor’s purpose for this expedition seems to have been to obtain recognition and gifts from other rulers. The voyagers did not intend to conquer or colonize, but they were prepared to use military force against those who refused to respect them.
Near the end of the voyage Zheng He’s ships encountered pirates in the Sumatran port of Palembang. The pirate leader pretended to submit, with the intention of escaping. However, Zheng He started a battle, easily defeating the pirates — his forces killing more than 5,000 people and taking the leader back to China to be beheaded.
Five more voyages followed before Emperor Yongle’s death in 1424; they included excursions to Hormuz — the Arab port at the mouth of the Persian Gulf — and the coast of eastern Africa, from which He returned with giraffes, zebras, and other items unfamiliar to the Chinese.
On his seventh and final voyage, from 1431 to 1433, Zheng He apparently died at sea and was likely buried off the coast of India, although some of his descendants believe that he made it back to China and died soon after his return.
