Before America entered World War II, twenty-two U.S. citizens went to England and volunteered with the Royal Navy. Commissioned between September 1939 and November 1941, they fought in the Battle of the Atlantic and on a variety of fronts. While the history of Americans serving in the Royal Air Force is well known, the story of these naval volunteers has not been previously told. Most trained at the Royal Naval College in Greenwich, but since foreign military service was against U.S. law, their names were never made public. Now, after years of research, their identities and the details of their contributions can be made known.

This unique WWII history combines the memoirs of a Nazi Admiral with secret British naval reports for a comprehensive view of the U-Boat war. The memoirs of Admiral Karl Dönitz, Ten Years and Twenty Days, are a fascinating first-hand account of the Battle of the Atlantic as seen from the headquarters of the U-boat fleet. Now, noted naval historian Jak P. Mallmann Showell has combined Dönitz's memoirs in a parallel text with the British Admiralty's secret Monthly Anti-Submarine Reports to produce a unique view of the U-boat war as it was perceived at the time by both sides. The British Monthly Anti-Submarine Reports were classified documents issued only to senior officers hunting U-boats. They were supposed to have been returned to the Admiralty and destroyed at the end of the War, but by chance a set survived in the archives of the Royal Navy's Submarine Museum in Gosport. They offer significant and hitherto unavailable insight into the British view of the Battle of the Atlantic as it was being fought. With expert analysis of these firsthand sources from opposing sides of the conflict, Jak P. Mallmann Showell presents what may be the most complete contemporary account of the desperate struggle in the North Atlantic during the Second World War.

Due to Enemy Action tells for the first time a World War II story that spans generations and straddles two centuries, a story that begins with the dramatic Battle of the Atlantic in the 1940s and doesn't conclude until an emotional Purple Heart ceremony in 2002. Based on previously classified government documents, military records, personal interviews, and letters between crew members and their families, this is the saga of the courageous survival of ordinary sailors when their ship was torpedoed and their shipmates were killed on April 23, 1945, and the memories that haunted them after the U.S. Navy buried the truth at war's end. It is the story of a small subchaser, the Eagle 56, caught in the crosshairs of a German U-boat, the U-853, whose brazen commander doomed his own crew in a desperate, last-ditch attempt to record final kills before his country's imminent defeat. And it is the account of how one man, Paul M. Lawton, embarked on an unrelenting quest for the truth and changed naval history. Author Stephen Puleo draws from extensive personal interviews with all the major players, including the three living survivors (and a fourth who emerged as the book went to press); a senior U.S. naval archivist who worked with German historians after the war to catalog U-boat movements; and the son of the man who commanded America's sub-tracking "Secret Room" during the war. Due to Enemy Action also describes the final chapter in the Battle of the Atlantic, tracing the epic struggle that began with shocking U-boat attacks against hundreds of defenseless merchant ships off American shores in 1942 and ended with the sinking of the Eagle 56, the last American warship sunk by a German U-boat.

"In Defeating the U-boat: Inventing Antisubmarine Warfare, Newport Paper 36, Jan. S. Breemer tells the story of the British response to the German submarine threat. His account of Germany's 'asymmetric' challenge (to use the contemporary term) to Britain's naval mastery holds important lessons for the United States today, the U.S. Navy in particular. The Royal Navy's obstinate refusal to consider seriously the option of convoying merchant vessels, which turned out to be key to the solution of the U-boat problem, demonstrates the extent to which professional military cultures can thwart technical and operational innovation even in circumstances of existential threat. Although historical controversy continues to cloud this issue ... Breemer ends his lively and informative study with some general reflections on military innovation and the requirements for fostering it."--Foreword.
