From destroyers and P-boats, Q-boats to trawlers, even the submarines themselves would fight duels with the U-boats in their quest to retain mastery of the seas. Focusing on this aspect of the war at sea, Newbolt relates many of the extraordinary incidents that defined this arduous campaign, from the Baltic to the North Sea via the Sea of Marmora.
