Established in 1857 between the towns of Westport and Kansas, Missouri, the 49-acre Union Cemetery was intended for both communities. Thus, the cemetery was not named after the Union Army, but for the union of the two communities. In 1889, the town of Kansas changed its name to Kansas City, and annexed Westport in 1897. Today, the cemetery is located within downtown Kansas City. Many notable local figures are interred in Union Cemetery, including George Caleb Bingham, a 19th-century painter, and Alexander Majors, who helped establish the Pony Express. The 8' tall granite obelisk commemorates 15 Confederate prisoners of war who died in Kansas City. Originally buried in the city cemetery, their remains were subsequently interred in Union Cemetery, although the location of the individual graves are not known. Two bronze tablets fastened to the monument list the names of the prisoners, who were taken during the Battle of Westport, the turning point in the Missouri Campaign of Confederate Major General Sterling Price. The lot is located in the northeast section of the cemetery and it is identified as stop #15 in the cemetery's walking tour.
