Plunged into depression after a brief post-war boom the ships & men of the British merchant navy found themselves called upon to repeat their sacrifice to the menace of German hostility within twenty years of the end of the 'war to end all wars'. For over three years until the Royal Navy bettered the German U-Boat the merchant navy maintained the supply of food raw materials & the sinews of war against appalling odds until victory ushered in a new age of peace & prosperity. It was not to last for long. Within a generation the merchant navy had all but vanished its companies wound up its men & women cast aside its loss to the nation yet to be appreciated in one of the quietest yet most fundamental changes to affect this country at the end of the millennium. The final instalment in Richard Woodman's ground-breaking five-volume series is as richly illustrated as the previous four & draws to a conclusion this critically acclaimed study into the history & development of the merchant navy.
