Frustrated in his hopes of a peaceful accommodation, the young captain now saw that nothing was left but the arbitrament of arms. Assembling his troops, preparatory to his departure from the capital, he made them a brief address. He protested that the step which he and his brave companions were about to take was not an act of rebellion against the Crown. It was forced on them by the conduct of the governor himself.
The commission of that officer gave him no authority over the territory of New Toledo, settled on Almagro's father, and by his father bequeathed to him. If Vaca de Castro, by exceeding the limits of his authority, drove him to hostilities, the blood spill in the quarrel would lie on the head of that commander, not on his. "In the assassination of Pizarro," he continued, "we took that justice into our own hands which elsewhere was denied us. It is the same now, in our contest with the royal governor.
We are as true-hearted and loyal subjects of the Crown as he is." And he concluded by invoking his soldiers to stand by him heart and hand in the approaching contest, in which they were all equally interested with himself.
The appeal was not made to an insensible audience. There were few among them who did not feel that their fortunes were indissolubly connected with those of their commander; and while they had little to expect from the austere character of the governor, they were warmly attached to the person of their young chief, who, with all the popular qualities of his father, excited additional sympathy from the circumstances of his age and his forlorn condition. Laying their hands on the cross, placed on an altar raised for the purpose, the officers and soldiers severally swore to brave every peril with Almagro, and remain true to him to the last.
In point of numbers, his forces had not greatly strengthened since his departure from Lima. He mustered but little more than five hundred in all; but among them were his father's veterans, well seasoned by many an Indian campaign. He had about two hundred horse, many of them clad in complete mail, a circumstance not too common in these wars, where a stuffed doublet of cotton was often the only panoply of the warrior. His infantry, formed of pikemen and arquebusiers, was excellently armed.
