Crebin, Edward Horace. "Adrift."
An ocean liner is sunk (torpedoed?) suddenly in the South Atlantic during a voyage either to or from South Africa and a handful of survivors clamber aboard an overloaded life-raft. Hours pass, and many begin to lose their will for survival - but not a Royal Navy admiral's daughter. She gives comfort to all, especially the children among them, never once believing their fate doomed. Instead, she encourages the survivors to put their hope in rescue by a Royal Navy ship. When one South African castigates the Navy ("Where's the Navy?" he cries out belligerently), she takes charge of the life-raft and threatens to toss the man overboard. Shortly thereafter she senses a ship over the horizon and indeed it turns out to be a Royal Navy destroyer searching for the liner's survivors. They're rescued in due course. In a coda, as all are being pulled aboard the destroyer, the admiral's daughter says - probably in a "There'll always be an England" voice! - to two children she'd been keeping warm within a voluminous Harris tweed coat:
Remember, remember this moment when you grow up. Then you will realize what many people seem to forget: the Navy, above all, stands for - Protection.
