History & Significance

Fort Iaqua was established on August 5, 1863, primarily as a Civil War-era post on the travel route connecting Fort Humboldt and Fort Gaston. It functioned as one of several support posts for Fort Humboldt during operations in the Bald Hills War.

Company A of the California Volunteers, commanded by Captain Long, relocated to the new fort positioned between Kneeland's Prairie and the head of Yager Creek. This repositioning aimed to improve oversight of Indian movements and hostilities across the Yager Creek, Van Duzen River, and upper Mad River areas, reflecting a tactical shift to concentrate forces more effectively during winter campaigns.

Company A Company A occupied the post from May 1, 1865, until ordered to the Presidio of San Francisco for muster out on November 30, 1865. The military post remained operational until 1866. No remains of the fort survive today.
