Captain Jack's Stronghold was a holdout of the Modoc people that is located between Tulelake and Canby, California. The stronghold, which is now part of Lava Beds National Monument, is named for Native American chief Kintpuash who was also known as Captain Jack. During the Modoc War in 1873, Captain Jack along with 53 Modoc warriors, and numerous women and children in a band of 160, managed to hold out against the United States Army which outnumbered them by as much as 10 to 1 for several months.
The Modoc retreated to this area because it was part of their traditional territory where they had hunted and lived before the start of the California genocide, when agents of the United States government assisted by private citizens began the systematic killing of thousands of indigenous peoples of California in the mid 19th century. Many of the brutal acts carried out against native populations were encouraged, tolerated, and perpetuated by state authorities and militias.
