A third voyage took place in 1779 under the command of
Ignacio de Arteaga with two armed
corvettes: the
Favorita under Arteaga and the
Princesa under Bodega y Quadra. With Arteaga on the
Favorita was second officer Fernando Quiros y Miranda, surgeon Juan Garcia, pilot Jose Camacho, and second pilot Juan Pantoja y Arriaga. With Bodega y Quadra on the
Princesa was second officer Francisco Antonio Mourelle, surgeon Mariano Nunez Esquivel, pilot Jose Canizares, and second pilot Juan Bautista Aguirre. The expedition's objective was to evaluate the Russian penetration of Alaska, search for a Northwest Passage, and capture
James Cook if they found him in Spanish waters. Spain had learned about Cook's 1778 explorations along the coast of the Pacific Northwest. In June 1779, during the expedition of Arteaga and Bodega y Quadra, Spain entered the
American Revolutionary War as an ally of France, precipitating a parallel
Anglo-Spanish War, which continued until the 1783
Treaty of Paris. Arteaga and Bodega y Quadra did not find Cook, who had been killed in Hawaii in February 1779. During the voyage, Arteaga and Bodega y Quadra carefully surveyed Bucareli Bay, then headed north to
Port Etches on
Hinchinbrook Island. They entered
Prince William Sound and reached a latitude of 61°, the most northern point obtained by the Spanish explorations of Alaska. They also explored
Cook Inlet, and the
Kenai Peninsula, where a possession ceremony was performed on August 2, in what today is called Port Chatham. Due to various sicknesses among the crew, Arteaga returned to California without finding the Russians. Throughout the voyage, the crews of both vessels endured many hardships, including food shortages and scurvy. On September 8, the ships rejoined and headed south for the return trip to San Blas. Although the Spanish were normally secretive about their exploring voyages and the discoveries made, the 1779 voyage of Arteaga and Bodega y Quadra became widely known.
Lapérouse obtained a copy of their map published in 1798. Mourelle's journal was acquired and published in London in 1798 by Daines Barrington. After these three exploration voyages to Alaska within five years, there were no further Spanish expeditions to the Pacific Northwest until 1788, after the
Treaty of Paris ended the war between Spain and Britain. During the war, Spain dedicated the port of San Blas to the war effort in the Philippines. Voyages of exploration were suspended. Support of Alta California, which depended upon San Blas, was minimal. By 1786 Alta California had become nearly self-supporting and peace with Britain was restored, making further voyages to Alaska possible. ==1788 voyage of Martínez and Haro==
