Here Padre Tomas de la Pena planted the cross, erected an _enramada_, or brush shelter, and on January 12, 1777, said mass, dedicating the new Mission to the Virgin, Santa Clara, one of the early converts of Francis of Assisi.
On February 3, 1777, the new governor of Alta California, Felipe de Neve, arrived at Monterey and superseded Rivera.

He quickly established the pueblo of San Jose, and, a year or two later, Los Angeles, the latter under the long title of the pueblo of "Nuestra Senora, Reina de los Angeles,"-- Our Lady, Queen of the Angels.
In the meantime, contrary to the advice and experience of the padres, the new Viceroy, Croix, determined to establish two Missions on the Colorado River, near the site of the present city of Yuma, and conduct them not as Missions with the Fathers exercising control over the Indians, but as towns in which the Indians would be under no temporal restraint.

The attempt was unfortunate.

The Indians fell upon the Spaniards and priests, settlers, soldiers, and Governor Rivera himself perished in the terrific attack.

Forty-six men met an awful fate, and the women were left to a slavery more frightful than death.
