Zebulon Montgomery Pike (1779 –1813) was an American soldier and explorer. As a United States Army captain in 1806–1807 he led an expedition to explore and document the southern portion of the Louisiana territory and to find the headwaters of the Red River, during which he recorded the discovery of what later was called Pikes Peak. Captured by the Spanish while wandering in present-day Colorado after his party got confused in its travels, Pike and his men were taken to Chihuahua, present-day Mexico and questioned by the governor. They were released later in 1807 at the border of Louisiana. In 1810 Pike published an account of his expeditions, a book so popular that it was translated into French, German and Dutch for publication in Europe. He later achieved the rank of brigadier general in the Army, serving during the War of 1812. He was killed during the Battle of York. This selective edition of Pike’s journals covers his Mississippi River and western expeditions, including related correspondence, field notebooks, and maps.
