On August 19, 1498, Columbus returned to Hispaniola. He found that many of the Spanish settlers there were unhappy. They thought there would be more gold in the New World. Some of them had rebelled while he was gone. Columbus had five of the rebellion's leaders hanged. He also tried to make the rest of the settlers happy by giving them land in Hispaniola. However, the settlers kept sending complaints to Spain. In 1499, Queen Isabella sent a man named Francisco de Bobadilla to Hispaniola. She gave him the power to do whatever he thought he should do. When he arrived in 1500, the first thing he did was to have Columbus arrested and sent back to Spain in chains.
