What is the real name of Uncle Sam?

Four years after the end of World War I, President Warren G. Harding orders U.S. occupation troops stationed in Germany to return home.

In 1917, after several years of bloody stalemate along the Western Front, the entrance of America’s fresh, well-supplied forces into the Great War—a decision announced by President Woodrow Wilson in April and provoked largely by Germany’s blatant attacks on American ships at sea—proved to be a major turning point in the conflict. American naval forces arrived in Britain on April 9, only three days after the formal declaration of war. On June 13, the American Expeditionary Force (AEF), commanded by the celebrated General John J. Pershing, reached the shores of France.
