On October 21, 1944, the American submarine USS Darter (SS-227) was patrolling the waters off northwestern Borneo, watching a narrow passage through which the Imperial Japanese Navy might soon send its most powerful warships. Thousands of miles of ocean separated the submarine from the beaches of Leyte, where American soldiers had begun the liberation of the Philippines the previous morning. Yet the events unfolding ashore were about to transform Darter’s fourth war patrol into one of the most consequential submarine operations of the Pacific War.
