Lieutenant Colonel Clay, the son of Sen. Henry Clay, was killed while leading his Second Kentucky Regiment in an attack side by side with Colonel Hardin's Illinois Regiment at Buena Vista. For a daguerrotype view of Clay's temporary grave, see Martha A. Sandweiss, Rick Stewart, and Ben W. Huseman, Eyewitness to War: Prints and Daguerreotypes of the Mexican War, 1846-1848 (Fort Worth: Amon Carter Museum; Washington D.C.: Smithsonian Press, 1989), p. 119. Sam is a bit careless in this sketch. end
