About Zebulon Pike:
Zebulon Montgomery Pike is named. As a United States Army captain in 1806–1807, he led the Pike Expedition, sent out by President Thomas Jefferson, 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. The Pike expedition coincided with other Jefferson expeditions including the Lewis and Clark Expedition (1804–1806) and the Thomas Freeman and Peter Custis expedition (1806). The Pike Expedition traveled through present-day Colorado after his party confused their location. This led to capture by Spanish, who sent Pike and his men to Chihuahua (present-day Mexico), and to questioning by the governor. They were released later in 1807 at the border of Louisiana.
There had so lately been a large force of Spanish cavalry at the village, which had made a great impression on the minds of the young men, as to their power, consequence, which my appearance with 20 infantry was by no means calculated to remove.Zebulon Pike
