Dace (SS-247) Darter (SS-227) Two submarines engage some of Japan's heaviest fighting ships, challenging U.S. landings in the Philippines. The submarines, USS Dace and USS Darter, sink two Japanese cruisers. Then, in her eagerness to get a third cruiser, the Darter goes aground on a reef. The Dace tries to save her sister ship by dislodging her. Unable to do this, she takes the Darter's crew aboard just before a timed demolition charge destroys the Darter.
