After the destruction of San Saba by the Indians, it was urged officially that the presidio of Amarillos, which protected, or rather which was to have protected the mission, should be abandoned, since it served no further purpose. (See Viceroy Amarillo's Letters, MSS., 1758, Bexar archives.) As a matter of fact it was not abandoned till some years later, serving first as a base of operations against the hostile Indians, and doubtless later as protector to some missions of which we shall have more to say.
