Your ship is part of a squadron off the west coast of France. Very heavy fog has rolled in an visibility is under 200m. In one sense this is good. German aircraft and u-boats will never see you. However this is also a very tense time. Your ships are following a zig-zag pattern but the fog prevents ships from co-ordinating their turns. The danger of collision is very high. The ships are using fog horns to identify their positions, but even this gets confusing. Suddenly you hear a very loud horn on your Port side. Everyone on deck is shocked to see the bows of a larger warship heading right for your side - it's a British cruiser, at least three times as large as your ship! The collision could cut you right in half!!!!
