The Allied coast watching network in the Solomons was one of the most successful intelligence operations of World War II. From their perches on jungle islands like Bougainville, coast watchers tracked Japanese shipping, sent warnings of impending air raids, and played a pivotal role during the 1942 battle of Guadalcanal when their information helped the U.S. Navy intercept and destroy twelve Japanese transports. Their existence was denied during the war, but the coast watchers' remarkable stories of espionage and survival come to life in these firsthand accounts.
