During his residence in Spain Alvarado obtained under a commission from the crown, dated April 17, 1538, the grant of the twenty-fifth part of all islands and lands which he might discover, with the title of count, and the seignory and jurisdiction over them; he was appointed governor and captain general for life over all such territories, and was authorized to erect on them three forts; he was, moreover, made alguacil mayor in perpetuity, and exempted from all interference by judges or other officers in everything pertaining to the fitting-out of his fleets. The expedition was to be made at his own expense, and he was to take a westerly direction toward China and the Spice Islands.[XII‑4] From a letter of the viceroy of Mexico we also learn that he was authorized to extend his explorations northward,[XII‑5] and that the emperor directed all the principal officials of the New World to aid in the arrest and punishment of any of Alvarado's subordinates who, when discoveries had been made, should revolt, fail to fulfil missions intrusted to them, or disobey him under any pretext. No clemency would be extended by the crown to such offenders. These privileges were granted in consideration of his services in the conquests of Mexico and Guatemala.[XII‑6] Early in 1539 the adelantado set sail from Spain, accompanied by his wife Doña Beatriz de la Cueva,[XII‑7] and on the 4th of April landed in state at Puerto de Caballos, with three large vessels well filled with provisions, materials of war, and all things needed to equip a second fleet on the shores of the South Sea. He was attended by a large retinue of cavaliers. Among his troops were three hundred arquebusiers all well armed and accoutred.[XII‑8] [Sidenote: EXTENSIVE PREPARATIONS.] Collecting a large number of natives he at once began the task of transporting his ponderous freight toward the coast of Guatemala. Anchors each weighing three or four hundred pounds, artillery and munitions, iron, chain cables, heavy ship tackle, and cases of merchandise were dragged along by Indians yoked together like draught-animals or carried on their naked shoulders, to be conveyed a distance of a hundred and thirty leagues across a mountainous and difficult country. Forty-three days were consumed in making the journey to Gracias á Dios.[XII‑9] Numbers of the unfortunates succumbed and dropped senseless, only to receive the curses of the commander as he ordered their burdens to be placed on the backs of others, who were constantly arriving in fresh relays from Guatemala. In this manner he pushed on toward the port of Iztapa, where the frames of a number of ships had already been constructed.[XII‑10] On his arrival Alvarado spared no expense in completing his armament, not only using all his own available means, but borrowing largely and purchasing vessels on credit.[XII‑11]
