Summary: Compilation of pre-1940 Royal Navy stock footage, overlaid with sailors' songs, martial tunes and a self-confident commentary, records peacetime Fleet manoeuvres and exercises, including engine room scenes, destroyers at sea (HMS Viceroy D.91,) HMS Hood and HMS Rodney opening fire, Fleet Air Arm planes flying off HMS Courageous ("heroic end"), destroyers (HMS Broadwater H.81) firing torpedoes, forming smoke screens and dropping depth charges, now "against the nefarious U-boat".
