History & Significance

Established on January 30, 1853, under Brevet Lieutenant Colonel Robert C. Buchanan of the 4th Infantry Regiment, Fort Humboldt occupied a strategic bluff overlooking Humboldt Bay in what is now Eureka, California. The fort sat on a bluff overlooking Humboldt Bay and served as both a protective post and a supply depot for other installations such as Fort Gaston in Hoopa and Fort Bragg in northern Mendocino County.

At its peak, the fort had 14 buildings all of crude plank construction. The post emerged from the discovery of gold in the Trinity River in May 1849, which set the stage for conflict between Native Americans and settlers and gold seekers that flooded into the region.

Captain Ulysses S. Grant, after being decorated for bravery in the Mexican-American War, was posted to Fort Humboldt in 1854, but the isolation did not appeal to him, and after serving as commanding officer of Company F for six months, he resigned his commission. On September 14, 1867, the last unit was withdrawn from Fort Humboldt and the post was abandoned, though in 1955 the area was deeded to the State of California with the understanding that the state would reconstruct historic buildings, eventually becoming a state historic park dedicated to interpreting both military and Native American history.
