Cuba was launched in 1511, and Pedro de Alvarado was accompanied by his brothers. Soon after the invasion, Alvarado was managing a prosperous hacienda in the new colony. It is around this time that Pedro de Alvarado emerges into the historical record as a prosperous and influential hacienda-owner, already well connected with Velázquez, who was now governor of Cuba. Grijalva expedition, 1518 Diego Velázquez, the governor of Cuba, was enthused by Francisco Hernández de Córdoba's report of gold in the newly discovered Yucatán Peninsula. He organised an expedition consisting of four ships and 260 men. He placed his nephew Juan de Grijalva in overall command; Pedro de Alvarado captained one of the ships. The small fleet was stocked with crossbows, muskets, barter goods, salted pork and cassava bread. The fleet left Cuba in April 1518, and made its first landfall upon the island of Cozumel, off the east coast of Yucatán. The Maya inhabitants of Cozumel fled the Spanish; the fleet then sailed south from Cozumel, along the east coast of the peninsula. The Spanish spotted three large Maya cities along the coast. On Ascension Thursday the fleet discovered a large bay, which the Spanish named Bahía de la Ascensión. Grijalva did not land at any of these cities and turned back north to loop around the north of the Yucatán Peninsula and sail down the west coast. At Campeche the Spanish opened fire against the city with small cannon; the inhabitants fled, allowing the Spanish to take the abandoned city. The Maya remained hidden in the forest, so the Spanish boarded their ships and continued along the coast. At Champotón, the fleet was approached by a small number of large war canoes, but the ships' cannon soon put them to flight. At the mouth of the Tabasco River the Spanish sighted massed warriors and canoes but the natives did not approach. By means of interpreters, Grijalva indicated that he wished to trade and bartered wine and beads in exchange for food and other supplies. From the natives they received a few gold trinkets and news of the riches of the Aztec Empire to the west. The expedition continued far enough to confirm the reality of the gold-rich empire, sailing as far north as Pánuco River. At the Papaloapan River, Alvarado ordered his ship upriver, leaving the rest of the small fleet behind to wait for him at the river
