Velázquez organized another expedition, hoping to trade with the Mayans for their gold, "for there must have been much there." He put his nephew, Juan de Grijalva, in command of four ships which departed Cuba in January, 1518. Grijalva sailed along the Yucatan and then headed northwards following the Mexican coastline, exploring and trading with the natives as the opportunity arose. When Grijalva returned in October he brought back a profit of 20,000 crowns; but Velázquez was angry with his nephew and felt the returns did not justify the time and effort.
