A political cartoon concerning the monetary proposal for peace between President Polk and General Paredes of Mexico during the Mexican American War. Polk and secretary of the treasury Robert J. Walker fire “Secret Service Money, $2,000,000” across the Rio Grande from the “U.S.A. Peacemaker” cannon. The coins fill the large money bag, “Mexican Sub Treasury,” held by the wide-eyed Paredes. King Luis Phillippe of France and Queen Victoria witness the scene. The suspicious Louis Phillippe fears the expansionist “Yankees” and exclaims, “I shall send a fleet of observation to the Gulf at once!” Victoria begrudges the United States’ possession of California and offers to act as mediator to “Friend Polk.” Polk declines the offer, sneers about foreign involvement, and asks for more “ammunition” from Walker. Walker, kneeling by the filled “U.S. Treasury” chest, gleefully complies and boasts about the infinite bounty from his “free trade measures and sub-treasury system.” “Mediation and Pacification,” lithograph by H.
