But while due observance of mourning was shown for the loss which the colonists had sustained in Alvarado's death, it was necessary to decide upon the important matter of the government of the province. Francisco de la Cueva had been left lieutenant-governor, but although this appointment was approved by the viceroy[XVIII‑4] and the cabildo was ordered by him to recognize Cueva until his Majesty's wishes should be known, the members took the matter into their own hands and elected Doña Beatriz governor. This anomalous proceeding was discussed at a special session, and the reasons assigned for taking such a step were that it was deemed necessary for the peace, security, and interest of the country. As soon as the decision was reached the cabildo went in a body to the house of Doña Beatriz and tendered her the appointment. Her violent grief for the loss of her lord did not prevent her from assuming rulership according to the wish of the authorities. Thanking the municipality for the honor, she accepted the position and promised to serve his Majesty with zeal and devote herself to the welfare of the province in the prescribed form of words. The ceremony of installation immediately followed in the presence of the bishop and Francisco de la Cueva, after which the widow of Alvarado took the oath in due form, and thereupon appointed her brother, Francisco de la Cueva,[XVIII‑5] lieutenant-governor, giving him full power to act for her in all matters pertaining to the government, except the disposal of repartimientos of Indians which might become vacant; this prerogative she reserved to herself. Her brother's appointment was recognized by the cabildo on the following day, Saturday the 10th of September.[XVIII‑6] * * * * * [Sidenote: DESTRUCTION OF SANTIAGO.]
