De Loaísa's expedition was conceived both as a rescue mission and a voyage of discovery. The Victoria, a vessel from Magellan's expedition to the Pacific, had returned to Spain in 1522 with word that her sister ship the Trinidad had last been seen attempting to return home by sailing east from the Spice Islands to South America. De Loaísa was ordered to seek Trinidad, or news of her fate, by voyaging along her expected return route to Spain. Failing this he was to locate and colonise Magellan's Spice Islands, and also to bring back news of the semi-mythical land of Ophir which Spanish scholars believed may be somewhere near China. For this purpose, de Loaísa was assigned seven vessels and a total of 450 men including tradesmen and administrators for the Spice Islands settlement.
Atlantic voyage
The expedition set sail from Corunna on July 24, 1525. It consisted of seven ships, Santa María de la Victoria, Sancti Spiritus, Anunciada, San Gabriel, Santa María del Parral and San Lesmes and a patache, Santiago. De Loaísa was named captain along with Juan Sebastián Elcano, who had reached the Spice Islands in 1521 during the Magellan expedition. The fleet headed southwest to the Canary Islands and then south along the African coastline. In November 1525 de Loaísa moved west across the Atlantic to Brazil, reaching the Patagonian shore in January 1526. There was no sign of Trinidad, and de Loaísa decided to abandon the search for her and continue instead to the Spice Islands. However the weather was poor, and over the next several weeks, in high winds while trying to enter the Strait of Magellan, the ships alternately gathered and dispersed. Two ships, Sancti Spiritus and Anunciada were wrecked, and one, San Gabriel tacked into the Atlantic and deserted the expedition. The San Lesmes under the captaincy of Francisco de Hoces was driven south along the coast, possibly to a latitude of 57°, where the crew noted "an end of land" which could have been the first European sighting of Cape Horn. After some difficulty Hoces was able to steer his galleon northward once more, rejoining the other three vessels that remained with the expedition. On 26 May 1526, this diminished fleet of four ships, passed through the Strait and entered the Pacific.
Pacific voyage
The bad weather which had originally scattered de Loaísa's fleet continued in the Pacific. The four remaining vessels quickly lost sight of each other in the heavy rain and were unable to regroup when the storm finally passed on 1 June. The Santiago sailed north, and in a 10,000-kilometre voyage, reached the Pacific coast of Mexico in July 1526, achieving the first navigation from Europe to the western coast of North America. The San Lesmes disappeared entirely. Twentieth century speculation suggests she ran aground in the Tuamotus, either on the island of Anaa where a 1774 expedition found a cross erected on the beach, or off the Amanu atoll where an old Spanish cannon was later found. The third ship, Santa María del Parral, sailed the Pacific to Sangir off the northern coast of Sulawesi, where the ship was beached and its crew were variously killed or enslaved by the natives. Four survivors were rescued in 1528 by another Spanish expedition coming from Mexico. The last galleon, Santa Maria de la Victoria, was the only ship to reach the Spice Islands, landing in September 1526.
hypothesised that the San Lesmes, after being lost in storm off the coast of South America, island hopped through the Pacific, stopping in Tahiti, before being wrecked on the coast of New Zealand. New Zealand film makerWinston Cowie assesses the San Lesmes theory in his books and , the Spanish version of which was completed with of the Embassy of Spain to New Zealand, adding the of the Pouto Peninsula to Langdon's work. Cowie concludes that there is a possibility that the San Lesmes was wrecked on the Pouto Peninsula with more research required to take the theory from possibility to probability. Greg Scowen's fiction conspiracy thriller The Spanish Helmet is based on Langdon's theory.
