Conquest of Peru (1532)

In 1531, Pizarro once again landed on the coasts near Ecuador, the province of Coaque and the region of esmeraldas, where some gold, silver and emeralds were procured and then dispatched to Almagro. The latter had stayed in Panama to gather more recruits. Sebastián de Belalcázar soon arrived with 30 men. Though Pizarro's main objective was then to set sail and dock at Tumbes like his previous expedition, he was forced to confront the Punian natives in the Battle of Puná, leaving three or four Spaniards dead and many wounded. Soon after, Hernando de Soto, another conquistador who had joined the expedition, arrived with 100 volunteers and horses to aid Pizarro and with him sailed towards Tumbes, only to find the place deserted and destroyed. The two conquistadors expected that the settlers had disappeared or died under murky circumstances. The chiefs explained that the fierce tribes of Punians had attacked them and ransacked the place.

As Tumbes no longer afforded safe accommodations, Pizarro led an excursion into the interior in May 1532 and established the first Spanish settlement in Peru, San Miguel de Piura, and a repartimiento.

Leaving 50 men back at the settlement under the command of Antonio Navarro, Pizarro proceeded with his conquest accompanied by 200 men on 24 September 1532. After arriving at Zaran, de Soto was dispatched to a Peruvian garrison at Caxas. After a week, he returned with an envoy from the Inca himself, with presents and an invitation to visit the Inca ruler's camp.

Following the defeat of his brother, Huáscar, in the Inca Civil War, Atahualpa had been resting in the Sierra of northern Peru, near Cajamarca, in the nearby thermal baths known today as the Inca Baths. Arriving at Cajamarca on 15 November 1532, Pizarro had a force of just 110-foot soldiers, 67 cavalry, three arquebuses and two falconets. He sent Hernando Pizarro and de Soto to meet with Atahualpa in his camp. Atahualpa agreed to meet Pizarro in his Cajamarca plaza fortress the next day. Fray Vincente de Valverde and native interpreter Felipillo approached Atahualpa in Cajamarca's central plaza. After the Dominican friar expounded the "true faith" and the need to pay tribute to the Emperor Charles V, Atahualpa replied, "I will be no man's tributary." His complacency, because fewer than 200 Spanish remained, as opposed to his 50,000-man army, of which 6,000 accompanied him to Cajamarca, sealed his fate and that of the Inca empire.

Atahualpa's refusal led Pizarro and his force to attack the Inca army in what became the Battle of Cajamarca on 16 November 1532. The Spanish were successful. Pizarro executed Atahualpa's 12-man honor guard and took the Inca captive at the so-called Ransom Room. By February 1533, Almagro had joined Pizarro in Cajamarca with an additional 150 men and 50 horses.

Despite fulfilling his promise of filling one room (22 by 17 feet or 7 by 5 metres) with gold and two with silver, Atahualpa was convicted of 12 charges, including killing his brother and plotting against Pizarro and his forces. He was executed by garrote on 29 August 1533. Francisco Pizarro and de Soto were opposed to Atahualpa's execution, but Francisco consented to the trial due to the "great agitation among the soldiers", particularly by Almagro. De Soto was on a reconnaissance mission the day of the trial and execution and upon his return expressed his dismay, stating, "he should have been taken to Castile and judged by the emperor." King Charles later wrote to Pizarro: "We have been displeased by the death of Atahualpa, since he was a monarch and particularly as it was done in the name of justice."

Pizarro advanced with his army of 500 Spaniards toward Cuzco, accompanied by Chalcuchimac, one of the leading Inca generals of the north and a supporter of Atahualpa, who was subsequently burned at the stake. Manco Inca Yupanqui joined Pizarro after the death of Túpac Huallpa. During the exploration of Cuzco, Pizarro was impressed and through his officers wrote back to King Charles I of Spain, saying: "This city is the greatest and the finest ever seen in this country or anywhere in the Indies... We can assure your Majesty that it is so beautiful and has such fine buildings that it would be remarkable even in Spain."

The Spanish sealed the conquest of Peru by entering Cuzco on 15 November 1533. Jauja, in the fertile Mantaro Valley, was established as Peru's provisional capital in April 1534, but it was high up in the mountains and too distant from the sea to serve as the capital. Pizarro founded the city of Lima on Peru's central coast on 6 January 1535, which he considered to be one of the most important things he had created in life.

By early 1536, Manco Inka, supported by an army of perhaps 100,000 people, initiated a siege of Cuzco. At the same time, smaller Incan expeditionary forces moved to destroy other European strongholds. In the three years of continuous warfare since the arrival of Pizarro, Incan military leaders had become familiar with Spanish military tactics and developed effective counters. Perhaps the most effective of these military innovations was the one that dealt with the Europeans' greatest advantage on the battlefield: horses. Incan soldiers would offer battle but hold their position until the Spaniards had concentrated their cavalry in order to break the indigenous line. They would then fall back before the cavalry charge and draw the Europeans into a canyon where prepositioned forces could crush them under avalanches of rocks and missile weapons. Instead of charging the numerically inferior Europeans as they had done early on, Incan soldiers used their discipline and knowledge of the terrain in order to draw the armoured cavalry charge into a death trap. Well documented battlefield deaths show that many more Spaniards died in these battles than in the early days of the war when theoretically the Inca had a much greater advantage. Despite winning the majority of the battles, the inability of the Incan forces to overwhelm Cuzco's fortifications, manned as they were by only 200 fighting men armed with gunpowder weapons, signalled the definitive victory of Spanish forces.

After the final effort of the Inca to recover Cuzco had been defeated by Almagro, a dispute occurred between Pizarro and Almagro respecting the limits of their jurisdiction, as both claimed the city of Cuzco. The king of Spain had awarded the Governorate of New Toledo to Almagro and the Governorate of New Castile to Pizarro. The dispute had originated from a disagreement on how to interpret the limit between the governorates. This led to confrontations between the Pizarro brothers and Almagro, who was eventually defeated during the Battle of Las Salinas (1538) and executed. Almagro's son, also named Diego and known as El Mozo, was later stripped of his lands and left bankrupt by Pizarro.

Atahualpa's wife, 10-year-old Cuxirimay Ocllo Yupanqui, was with Atahualpa's army in Cajamarca and had stayed with him while he was imprisoned. Following his execution, she was taken to Cuzco, given the name Doña Angelina and made the concubine of Francisco Pizarro. By 1538, it was known she had borne Pizarro two sons, Juan and Francisco.
