July, 1950. The start of the Korean War and the first battle between Communists and American soldiers, the men of Task Force Smith and the 24th Infantry Division. It was a battle that caught the U.S. Army by surprise, a stinging defeat, forgotten in the mists of history. The Five Days of Osan is a fictional story taking place during the initial battle between Task Force Smith and their communist opponents, a tale of mistakes and incompetence, as well as integrity and courage under impossible circumstances, a tale that hearkens to the Spartans of Thermopylae, where there is victory even in the face of complete defeat.
