of his ships was lost in a storm, Ulloa paused to repair the other two ships, and then resumed his voyage, eventually reaching the northern end of the Gulf. Unable to find the Strait of Anián, Ulloa turned south and sailed along the eastern coast of the Baja California peninsula, landing at the Bay of La Paz. After taking on supplies of wood and water, Ulloa rounded the tip of the peninsula with great difficulty and sailed northward along the western shore of the peninsula, in the Pacific Ocean. The progress of his small ships was hampered by the fierce winds and high seas he encountered, eventually forcing him to turn back to Acapulco. The voyage eventually reached 28° north latitude (near the Isla de Cedros). Voyages in 1540 and 1541 to Baja California were sponsored by Cortés's rival, the Viceroy of New Spain. These voyages were led by Hernando de Alarcón (1540) and by Francisco de Bolaños (1541). The voyage by Alarcón was meant to be coordinated with Francisco Vásquez de Coronado's overland expedition; Alarcón penetrated the lower Colorado River, perhaps as far as the modern California-Arizona boundary (but did not meet up with Coronado's expedition). The voyage of Bolaños provided little new information not already known in New Spain. Application of the name California to this part of the west coast of North America is attributed by some to Bolaños,History of Cerritos. however others insist that the name first appears in work written by Alarcón. The governor of Guatemala also determined to build a Pacific fleet on the west coast of Guatemala, for use in an attempt to cross the Pacific to Asia. Ferdinand Magellan, the Portuguese explorer sailing for Spain, had shown in 1521 that the Pacific Ocean could be crossed from South America. Hence, beginning in 1536, using hardware from Spain (such as anchors) hauled across the isthmus of Central America, and local hardwoods, a flotilla of some thirteen ships was built over the next four years. After much difficulty, the larger number of these ships (under the command of Ruy López de Villalobos) was ordered to make the first crossing of the Pacific Ocean from North America to the Philippines. A smaller number was placed under the command of Juan Rodríguez Cabrillo, a Portuguese navigator sailing for the Spanish Crown. Cabrillo was ordered north along the west coast of North America to explore the expected
