The date of the expedition to Dabaibe, in which so many men were lost, is not certain; but Vasco Nuñez saw the necessity of putting forward a defence, which he did in a letter to the King on the 16th of October, 1515.[707] In this letter, besides describing the really insuperable obstacles in the way of a successful expedition in that direction,—in which the lack of food, owing to the ravages of the locusts, bears a prominent part,—he attacks Pedrárias and his government very severely. The doings of Arbolancha in Spain are not known. There is a letter of the King to Pedrárias, dated Sept. 27, 1514, appointing Vasco Nuñez _adelantado_ of the coast region which he had discovered.[708] We have several letters of the King to Pedrárias, to the new _adelantado_, and to other officers, on November 23 and 27.[709] The next document of importance is the narrative of Espinosa’s expedition, written by himself. It is printed in the _Documentos inéditos_ (vol. ii. pp. 467-522), with some corrections by the editors; but it may be found in the original spelling, and without such corrections, in another volume of that series,[710] where the date of 1514 is most erroneously assigned to it. The _licenciate_ Gaspar de Espinosa came to Tierra-Firme with Pedrárias as _alcalde mayor_. Soon after his arrival at Antigua he held the _residencia_ of Vasco Nuñez, and then is not heard of again until he is found in command of this expedition. He founded Panamá (for the first time) and returned to Antigua, whence he followed Pedrárias to Acla to try Vasco Nuñez for treason. He unwillingly convicted him, but recommended mercy. After the great explorer’s death he cruised in his vessels to the coast of Nicaragua; and later he played an important part in the conquest of Peru, and died at Cuzco while endeavoring to accommodate the differences between Pizarro and Almagro. The only other document of his which I have found is a _Relacion e proceso_ concerning the voyage of 1519.[711]
