When Almagro was informed of the arrival of Alfonso Alvarado at Abancay, he sent Diego Alvarado to wait upon him, attended by seven or eight horsemen, with orders to notify his commission as governor in these parts. Alfonso, after examining the commission, declared that he did not consider himself competent to decide upon an affair of such high importance, and that the documents ought to be communicated to the marquis.

Some of these conspirators contrived during the night to throw above fifty lances belonging to the cavalry
