No second-in-command had been named. Bitter experience had shown that designating a successor could incite rivalries, mutinies, and murder. Instead, Legazpi’s replacement was to remain unknown until the time of his death, when the survivors would be permitted to look in the commander’s cabin for a steel coffer “of about one palm in length and one hand and two fingers in width.” This hidden box, “nailed shut and wrapped in cloth with three royal seals, contained a piece of paper with the name of the substitute commander.
