On July 15, 1806, U.S. Army Lieutenant Zebulon Pike set out from St. Louis, Missouri, on a military reconnaissance mission into the uncharted western boundaries of the Louisiana Purchase. Officially tasked with locating the headwaters of the Arkansas and Red rivers, Pike’s small party crossed the Great Plains and recorded the massive Colorado summit that would later bear his name.
The perilous, largely unstated diplomatic scandal behind Pike’s journey was that his commander, General James Wilkinson, was secretly on the payroll of the Spanish Empire. Wilkinson issued Pike deliberately vague and contradictory instructions, a move that virtually guaranteed the young officer would stray into Spanish-controlled territory. Many historians believe this ambiguity was intentional: Pike’s true assignment was covert intelligence-gathering on Spain’s northern frontier. The result was predictable. Exhausted and freezing, Pike’s men were seized by Spanish authorities in New Mexico, igniting an international dispute that exposed the fragile—and often treacherous—politics of America’s early western expansion.
