"The homebound Superman encourages Americans to buy war bonds, to ration scarce supplies, and to donate to organizations like the Red Cross and the United States Services Organization (USO). In his adventures, Superman travels outside Metropolis to military training centers to lift the spirits of the troops and to prepare them for the action ahead. In one comic book adventure he travels to a fictional U.S. military training center, where he takes part in a mock war game by taking the side of the blue army in a simulated battle with the red army. Superman ferries blue troops across rivers, bombs red airfields with sandbags, locates red snipers with his x-ray vision, and finally tunnels through a mountain to lead blue troops into the red camp. Facing defeat, the red general implores his men to fight on. “What if they were Japs or Nazis?” he asks, “Would you let down the folks who are counting on your to save your country and the world?” At this point the red army summons the strength to repel the blues and win the game. Superman, happily experiencing a rare defeat, concludes that American soldiers are the real superheroes and congratulates the men for being “Super-Soldiers.” Still, from 1941 to 1945 there were stories of Superman’s periodic trips to the front lines, Siegel clearly designed one newspaper strip to draw the attention of American children to the evil of the enemy. In this strip, Hitler Mussolini, and Tojo (Japan’s prime minister) kidnap Santa Claus as part of their plan for world domination. Superman is forced to rescue Old Saint Nick and save Christmas. In addition to these occasional war stories, a number of powerful “Superman” magazine covers trumpeted the war effort, even though there were usually no corresponding stories inside to back up the symbolic cover art; Superman, seen through the periscope of a German U-boat, swimming furiously toward the submarine in the wake of the Allied ship that the sub just sank; Superman holding an eagle on his arm, standing proudly in front of the Stars and Stripes; Superman delivering supplies to an American machine-gun squad fighting in the jungles; Lois Lane, with an Army soldier, a Navy sailor, and a Marine, telling them with a wink, “You’re my Supermen.”"
