This documentary offers a profile of two of the Marine Corps' bloodiest battles. Perhaps the better known of the two, Tarawa, has come to symbolize the savage island fighting that characterized the war in the Pacific. Fought within an area the size of the Pentagon, three days of fighting claimed almost 10,000 lives. The second part deals with the return of the Marine Corps to their base on Guam. Seized early in the war, the island of Guam had a close relationship with the United States, and its loss was one that hurt deeply.
