ved at Mission San Jose....

Since no specific information is given, it may be assumed that this
expedition penetrated the area lying between Mt. Diablo and the
Livermore Valley, perhaps getting as far north as Walnut Creek. It is
stated and implied that the Sacalanes were in a condition of great
disorganization. They had been driven into the hills, apparently widely
scattered and probably seriously depleted in numbers.

LUIS PERALTA'S EXPEDITIONS

The last information we possess concerning this group of natives comes
from the year 1804. In 1803, a letter, dated May 11 at Loreto, from
Governor Arrillaga to the Viceroy (Archivo General de la Nacion, Ramo
Californias, Vol. 9, MS p. 433) mentions the fact that 20 Christians,
sent out by the missionaries of Santa Clara, were attacked and routed by
Gentiles who killed their "principal." In connection with this murder,
and with a supposed plot to destroy Mission San Jose, the testimony of
witnesses was taken a year later (Archivo General de la Nacion, Ramo
Californias, Vol. 9, MS pp. 437-439, June 21, 1804, San Jose, Luis
Peralta in charge). On September 27, 1804, from Santa Clara, in a letter
to an unnamed captain, Luis Peralta (Bancroft Trans., Prov. St. Pap.,
XVIII: 334) advised that the expedition he made against Gentile Indians
had no satisfactory results, because of lack of guides. On September 29,
Arguello, at San Francisco, wrote to Governor Arrillaga (Bancroft
Trans., Prov. St. Pap., XVII: 354) that he had ordered Peralta to go to
the "Sierra de San Jose" in pursuit of Gentile assassins of Christians,
but Peralta could not catch them.

Peralta went out a second time. Arguello, from San Francisco, on October
26, wrote again to Governor Arrillaga (Bancroft Trans., Prov. St. Pap.,
XVII, 358-359) that Peralta could not catch the killers of the Mission
Indian Jorge, but he did catch 11 Christians, and after leaving the
women and children at the mission, brought 32 "gandules" ("rogues,"
"rascals," a colloquial term for renegade Indians) to the Presidio.
Since the "Sierra de San Jose" was the coast range behind the East Bay
it is clear that the remnant of the people who originally inhabited the
interior had taken to the hills in a last stand against the invader.
After 1804 all mention of them ceases.

_The Cuevas Affair._--In 1805 occurred what is called the "Cuevas
Affair." This event has significance for the Alameda and Contra Costa
natives, rather than those of th
