In early 1775, Spain's Captain Bruno Heceta came ashore on the Pacific side of the Olympic Peninsula. It's not certain but he likely landed near the Hoh River where he and crew his claimed the country for the king of Spain before rowing back to their ship and sailing away. As brief as it was, this visit probably marks the first arrival of Europeans on the northwestern coast of Washington and may have signaled the first encounter between the Natives on the region and white men. That encounter was confirmed, violently, later when another Spanish vessel, the schooner Sonora, arrived off the coast near Destruction Island and was greeted by Indians in canoes who were interested in trading skins and fish for European goods. The next day sailors dispatched to get water were attacked, overwhelmed, and killed by Indians when they landed on the beach. It is not clear why the sailors were attacked-although it's possibly that the sailors entered a safe haven for women-but the Indians removed the iron from their boat and then paddled out to schooner and acted in a way that the remaining Spanish sailors believed was threatening. The Spanish opened fire, killing or wounding six or seven Indians, and then fled. A dozen years later, in a remarkably similar incident at the mouth of the Hoh River, six crewmen of the British Imperial Eagle were killed. Just who were the Indians the Europeans meet along this stretch of coast is still unclear: Although the Hoh seem a likely choice, anthropologists and historians suggest that the Natives could also have been Quileute, Quinault, or Queets. Regardless, those first encounters gave the Natives of the coast a reputation for fierceness and independence.
