was made difficult by the many independent polities in the region, rather than one powerful enemy to be defeated as was the case in central Mexico. After the Aztec capital Tenochtitlan fell to the Spanish in 1521, the Kaqchikel Maya of Iximche sent envoys to Hernán Cortés to declare their allegiance to the new ruler of Mexico, and the Kʼicheʼ Maya of Qʼumarkaj may also have sent a delegation. In 1522 Cortés sent Mexican allies to scout the Soconusco region of lowland Chiapas, where they met new delegations from Iximche and Qʼumarkaj at Tuxpán; both of the powerful highland Maya kingdoms declared their loyalty to the king of Spain. But Cortés' allies in Soconusco soon informed him that the Kʼicheʼ and the Kaqchikel were not loyal, and were instead harassing Spain's allies in the region. Cortés decided to despatch Pedro de Alvarado with 180 cavalry, 300 infantry, crossbows, muskets, 4 cannons, large amounts of ammunition and gunpowder, and thousands of allied Mexican warriors from Tlaxcala, Cholula and other cities in central Mexico; they arrived in Soconusco in 1523. Pedro de Alvarado was infamous for the massacre of Aztec nobles in Tenochtitlan and, according to Bartolomé de las Casas, he committed further atrocities in the conquest of the Maya kingdoms in Guatemala. Some groups remained loyal to the Spanish once they had submitted to the conquest, such as the Tzʼutujil and the Kʼicheʼ of Quetzaltenango, and provided them with warriors to assist further conquest. Other groups soon rebelled however, and by 1526 numerous rebellions had engulfed the highlands. Subjugation of the Kʼicheʼ Pedro de Alvarado and his army advanced along the Pacific coast unopposed until they reached the Samalá River in western Guatemala. This region formed a part of the Kʼicheʼ kingdom, and a Kʼicheʼ army tried unsuccessfully to prevent the Spanish from crossing the river. Once across, the conquistadors ransacked nearby settlements in an effort to terrorise the Kʼicheʼ. On 8 February 1524 Alvarado's army fought a battle at Xetulul, called Zapotitlán by his Mexican allies (modern San Francisco Zapotitlán). Although suffering many injuries inflicted by defending Kʼicheʼ archers, the Spanish and their allies stormed the town and set up camp in the marketplace. Alvarado then turned to head upriver into the Sierra Madre mountains towards the Kʼicheʼ heartlands, crossing the pass into the fertile valley of Quetzaltenango. On 12 February 1524 Alvarado's Mexican allies were ambushed in the pass
