Sheltering in the recently conquered Inca capital, the Spanish conquistadors resorted to desperate measures, but still succeeded in withstanding a ten-month siege, which ended in April 1537. What came to be known as the Battle of Cuzco solidified Spain’s hold on Peru.

　　The Incas had paid an enormous ransom in gold for the release of Atahuallpa—their king and god—after their loss at the Battle of Cajamarca (1532), but the conquistador leader, Francisco Pizarro, still had his prisoner garrotted in the end. Manco took his place as Inca ruler. At first content to be a puppet ruler, Manco rebelled when he realized how little authority he would have. Taking refuge in the Yucay Valley, he raised an army: warriors flocked there from all corners of Peru, and from Inca realms in Ecuador and Chile. Although Pizarro’s troops had been reinforced by fresh arrivals in the years since he had taken the Inca Empire with just 128 men, the Spanish were still overwhelmingly outnumbered.

　　Britannica Quiz A History of War In May 1536, the Incas were ready for revenge and attacked. They took the Spanish by surprise and managed to occupy most of the city. Crucially, they took the formidable citadel of Sacsahuaman. The conquistadors were forced to mount their own countersiege. Meanwhile, cut off from all support, they sent out parties to seek help from New Spain (Mexico). These excursions were intercepted, their members killed or captured. Manco set these Spanish prisoners to instruct his Inca warriors in the use of horses, swords, and guns. However, after months of fighting, the Spanish succeeded in cutting off supplies to Sacsahuaman: they then sallied forth to attack Manco’s headquarters at Ollantaytambo. This attack was repelled, but as Manco moved in upon Cuzco for the kill, his own force was taken by surprise by a column of Spanish soldiers returning from an expedition to Chile and led by Pizarro’s chief lieutenant, Diego de Almagro. The Incas were defeated, finally surrendering Cuzco on April 18, 1537, and the reign of the Spanish over Peru was confirmed—though not without further fighting, for Almagro, considering himself the victor and true conqueror, now waged war on Pizarro until being defeated and executed the following year.
