General George C. Crook was stationed at Fort Humboldt during the early days of his illustrious career. As a young Lt., Crook was the Fort's first adjutant, in charge of the daily paperwork and general orders. He was also in charge of the construction of the Fort.
Lt. Crook led many forays against Native Americans of the area and learned to use their tactics of battle in his later days during the Plains Indian Wars. He held great respect for Native people. The Apache named him "Grey Fox" out of their respect towards him.
In his later years, retired General Crook traveled the country speaking out against the harsh and unjust treatment of Native Americans by the U.S. Government.
