Saville serves out the First World War and the interwar years, and by the first years of the Second World War, he is in command of a squadron of three cruisers on convoy duty in the Pacific. He receives a message from a British merchantman just before it is sunk by the German raider Essen, but HMS Stratford, the flagship of Savilles squadron is too low on fuel for pursuit and the convoy cannot be left unguarded. Saville decides to remain with the convoy while his other two ships HMS Amesbury and HMS Cambridge chase after the raider. Cambridge then has to stop to pick up survivors from the merchantman, leaving the Amesbury on her own. Amesbury finds and attacks the Essen, scoring a major torpedo hit on the Essens bow, but is sunk with the loss of all but two hands, Petty Officer Wheatley and Signalman Andrew Canada Brown. Brown is the son of a mother keen on the navy and thus knows more about naval tactics, strategy and gunnery than most of his rank.The Essen picks up the two survivors. Meanwhile, news of the Amesburys fate reaches Saville in the Stratford. Saville decides to risk all and go after the Essen with Cambridge. While the Essen is anchored in a rocky lagoon forhours to carry out repairs, Brown manages to escape to the heights around the lagoon with a rifle back home, he had won marksmanship prizes. He then proceeds to pick off sailors working on the repairs, leading the Essens captain to use his ships AA guns and then big guns in vain attempts to dislodge Brown. Finally he sends a party of marines out to hunt Brown down, but just as they are about to kill him, they are recalled and the Essen departs. Brown collapses, seriously wounded. ........
