Book excerpt: The story of Allied merchant ships and crews who braved the frigid far north to extend a lifeline to Russia, filled with “sheer heroism and brazen drama” (Literary Review). During the last four years of the Second World War, the Western Allies secured Russian defenses against Germany by supplying vital food and arms. The plight of those in Murmansk and Archangel who benefited is now well known, but few are aware of the courage, determination, and sacrifice of Allied merchant ships, which withstood unremitting U-boat attacks and aerial bombardment to maintain the lifeline to Russia. In the storms, fog, and numbing cold of the Arctic, where the sinking of a ten thousand–ton freighter was equal to a land battle in terms of destruction, the losses sustained were huge. Told from the perspective of their crews, this is the inspiring story of the long-suffering merchant ships without which Russia would almost certainly have fallen to Nazi Germany.
