started out with only twenty-six men Casteñeda says to the southwest, but this is probably a mistake for northwest; for after wandering 150 leagues, or 405 miles, Diaz seems, according to the account, to have reached the great Colorado River of the west, where he found letters from Alarcon buried at the foot of a marked tree, which contained news of his having reached that place and then gone back to New Spain. Diaz followed up the eastern bank of the river for several days' journey; but I have not been able to learn anything concerning the conclusion of his campaign. During his absence[1] the Indians attacked the settlement at Suya and destroyed it, depriving Coronado of an important link of communication between his isolated position in the north and the Spanish advanced posts in the south.
The campaign of Diaz was probably begun in the winter of 1540-41, for the main part of Coronado's expedition was still in Sonora in October, 1540.
