Note 7 — INTRODUCTION

In his History of Oregon and California, Greenhow adds information to that given in his first volume, regarding these expeditions. His chief source of information was the work of Herrera, although he secured journals of some of the voyagers from W. H. Prescott. All of these expeditions were inspired by Hernando de Cortez. The first (1532) was headed by his kinsman Hurtado de Mendoza, whose lieutenant Juan de Mazuela brought back one vessel after his superior officer had been killed. In 1533, Hernando Grivalja and Diego Becerra were sent to search for the survivors. The former returned without touching mainland; Becerra was killed in a mutiny, and his pilot, Fortuño Ximenes, is supposed to have touched the southern end of the peninsula of Lower California. Farnham omits mention of Cortez's own expedition of 1535-36, when he also is supposed to have reached Lower California. In 1539-40, Francisco de Ulloa proved that this was not an island, and explored its coast to about 30° north latitude.—Ed.
