Obadiah M. Knapp (b. 1841), from Wallingford, Connecticut, was a student at Yale College (1860-1863) and a soldier in the U.S. Army during the Civil War and post-war years. After serving as an officer and hospital steward in the 125th U.S. Colored Regiment, Knapp traveled throughout the frontiers of Texas and New Mexico, becoming acquainted with Kit Carson and guarding the U.S. military installations in the region from the Native American populations.
