<P> Devil Dog is a motivational nickname for a U.S. Marine . It is said by US Marines to be based on the use of "Teufel Hunde" (sic) (idiomatic German: "Höllenhunde", which exactly means "hells dogs") by German soldiers to describe Marines fighting in World War I . </P> <P> According to United States Marine Corps legend, the moniker was used by German soldiers to describe U.S. Marines who fought in the Battle of Belleau Wood in 1918 . The Marines fought with such ferocity that they were likened to "Dogs from Hell ." The "Devil Dogs" nickname for Marines first appeared in newspapers in the United States in April 1918--about two months before the Battle of Belleau Wood . The LaCrosse Tribune ran a story about the nickname on April 27, 1918, and other newspapers used the story as early as April 14, 1918 . The Battle of Belleau Wood began on June 1, 1918 . </P> <P> The April 27th article from the LaCrosse Tribune was probably referring to the action on April 20, 1918, the first action between the Marines and the Germans . The Germans made several attacks against the Marines on that date and were unable to dislodge them . The article states that it was the first scrap between the Marines and the Germans, showing that it was prior to the major fighting in June . However, there are no sources to date of a German soldier referring to Americans as devil dogs . </P>
