Pershing and Brigadier General James Harbord, faced the formidable Imperial German Forces, commanded by Wilhelm, German Crown Prince. The battle began in early June and was characterized by fierce fighting in dense woods, as American soldiers fought tenaciously against entrenched German positions.American Marines earned a legendary reputation through their bravery during this battle, with the phrase “Teufel Hunden” (Devil Dogs) reportedly becoming associated with them, reflecting the fear they instilled in their enemies. The battle’s significance lies not only in its military outcome but also in its impact on American identity during the war. The fierce resistance by the Allies inflicted heavy casualties on the Germans and marked a critical turning point, leading to increased American involvement in the conflict. The eventual American victory at Belleau Wood boosted morale and showcased the effectiveness of U.S. forces on the Western Front, setting the stage for future Allied operations.
