The Battle of the Atlantic rages, and survival rides on fragile steel hulls crossing storm-lashed seas.Captain Alistair Cunningham commands HMS Valiant, a British destroyer tasked with shielding convoys from the German wolfpacks that stalk the depths. Each night brings fresh terror—torpedoes in the dark, flares that light the ocean with fire, and the cries of sailors cast into freezing waters.Beneath the waves, Korvettenkapitän Erik Brandt leads U-456, a hunter bound by duty to sink the very ships Cunningham must protect. In the crushing depths, his men endure hunger, fear, and the thunder of depth charges as they prowl the convoy lanes.Told through both perspectives, Grey Seas of Sorrow is a visceral story of endurance and sacrifice, where predator and prey blur, and the grey Atlantic consumes all.
