Manco Capac was by no means prepared to yield tamely to the situation. For a considerable time very little was effected on either side. The Incas were slowly recovering from the shocks and tribulations which they had undergone; the Spaniards, on the other hand, found their attention occupied by the unexpected arrival of a Spanish expedition commanded by Pedro de Alvarado. This leader had performed his part in the conquest of Mexico, and had now hastened to the South in order to ascertain what chances of enrichment were to be met with in the land, the reputation of which was now spreading itself abroad. For a while it looked very much as if open warfare would result between the rival parties. In the end, however, Pizarro consented to buy the departure of Alvarado, and this leader retired heavy in pocket. On the whole his visit had not proved unprofitable to the astute Pizarro, since many of Alvarado's men had remained in Peru to throw in their lot with him.
Pizarro and Almagro were now left in occupation of the Inca Empire. It was inevitable that jealousy should arise between the pair, and it was not long before the situation grew strained. Pizarro, true to his own interests, had insisted on returning to Spain in order to give an account of the doings in Peru. Needless to say, he employed the opportunity to obtain the royal sanction to advance still further his official position—somewhat at the expense of Almagro, of course. Almost directly after his return he founded the city of Lima, intending this to supersede Cuzco as the future capital of the country.
All this while the breach between Pizarro and Almagro had widened. In 1535 the latter, realizing that even the Empire of the Incas was not sufficiently large to hold the pair of Spanish leaders, determined to make for the South. The expedition was a tragic one. Almagro, though his spirit was undaunted, was now aged in years, and the barren country of the Atacama Desert and the attacks of the hostile Indians rendered the enterprise a failure from a monetary point of view. Almagro had invested all his fortune in this, and his affairs now became desperate.
In the meantime the crafty Pizarro had been permitted to enjoy very little peace and tranquillity in Peru. Manco Capac had bided his time, and his Indian subjects, fervently loyal to the sacred dynasty, had crowded about him in their thousands. The Peruvians now assumed the aggressive. Thousands of Inca troops scoured the country, and, falling on remote and unprepared bands of Spaniards, obtained some modicum of revenge in slaughtering all they found.
Encouraged by such minor successes, the Inca army advanced against the main bodies of the Spaniards. Some historians place the numbers of the native troops at no fewer than 200,000. With astonishing suddenness the situation became altered. Pizarro found himself besieged in Lima, while his brothers, shut up in Cuzco, experienced an equal difficulty in beating off the attacks of the serried native ranks. Had the Spanish army in Peru been left to its own devices, there is no doubt but that their doom would have been sealed. The irony of fate, however, chose this very moment for the return of Almagro. Marching up with his grim and travel-worn band, he found himself before Cuzco, surveying the beleaguered Spaniards and the investing Incas.
Manco Capac had gleaned something of the disputes between the European leaders. He made advances to Almagro, and did all he could to win him to his side; but Almagro, little cause though he had to love Pizarro, proved himself stanch. He was in consequence attacked by the Inca troops, but these he repulsed with heavy losses, and then entered Cuzco in triumph. Manco Capac himself escaped, and retired to the other side of the Andes.
Almagro was destined to receive small thanks for his intervention. The aged conquistador laid claim to the city as part of his own dominions, and this woke into fresh activity the warfare between himself and Francisco Pizarro. Almagro, defeated, lost his head, a white and seventy-year-old head though it was. His fate by no means ended the tragedies in Peru. The current of sinister events was running here in a strangely full flood. It was only three years afterwards that Pizarro himself was murdered by his enemies, the adherents of Almagro's son, whom they wished to see elevated to the Governorship of the country, an event which actually occurred, although it proved of very short duration.
