The Battle of the Atlantic was the longest continuous military campaign of the Second World War, raging from 1939 to 1945. It saw the might of the Royal Navy pitted against the Kriegsmarine. Germany’s secret weapon was their fleet of U-boats. They had the largest fleet of submarines in the world and this enabled them to play cat and mouse with the Allied forces to devastating effect. Hunting in ‘wolf-packs’ they would prey on merchant shipping and naval vessels. In this startling new book, Jak P. Mallmann Showell tells the story of this battle as viewed through the conning towers of these U-boats. Using surviving logs, written as the action unfolded. You taste the salt, smell the nauseating stench of the U-boats and hear orders being whispered quietly while diving back in time to the horrendous inhumanity of the Battle of the Atlantic.
