Book Description
During the last year of World War II the once surface-bound diesel-electric U-boat ushered in the age of ‘total undersea war’ with the introduction of an air mast, or 'snorkel' as it became known among the men who served in Dönitz's submarine fleet. U-boats no longer needed to surface to charge batteries or refresh air; they rarely communicated with their command, operating silently and alone among the shallow coastal waters of the United Kingdom and across to North America. At first, U-boats could remain submerged continuously for a few days, then a few weeks, and finally for months at a time, and they set underwater endurance records not broken for nearly a quarter of a century. The introduction of the snorkel was of paramount concern to the Allies, who strived to frustrate the impact of the device before war's end. Every subsequent wartime U-boat innovation was subordinated to the snorkel, including the new Type XXI Electro-boat ‘wonder weapon’. The snorkel's introduction foreshadowed the nearly un-trackable weapon and instrument of intelligence that the submarine became in the postwar world. This exhaustive study, the first of its kind, draws upon wartime documents from archives around the world to re-evaluate the last year of the U-boat's deployment, all its key technological innovations, the evolving operations and tactics, and Allied countermeasures. It provides answers to many long-standing questions about the last year of the war: How and why did U-boats patrol so close inshore? How effective was acoustic and anti-radar camouflage? Why was U-boat wireless communication so problematic? How did U-boats navigate so effectively submerged? What were the health implications of staying submerged for a month or more? What does an accurate snorkel-configuration look like? This new study is destined to become the authoritative reference for all these issues and many more.

Book Description
“Provides a wealth of information about . . . people who have gone through debt collectives, hospitals, bankruptcy, crime, homelessness—the list is huge.” —UK Historian Many people in the past—perhaps a majority—were poor. Tracing our ancestors amongst them involves consulting a wide range of sources. Stuart Raymond’s handbook is the ideal guide to them. He examines the history of the poor and how they survived. Some were supported by charity. A few were lucky enough to live in an almshouse. Many had to depend on whatever the poor law overseers gave them. Others were forced into the Union workhouse. Some turned to a life of crime. Vagrants were whipped and poor children were apprenticed by the overseers or by a charity. Paupers living in the wrong place were forcibly “removed” to their parish of settlement. Many parishes and charities offered them the chance to emigrate to North America or Australia. As a result, there are many places where information can be found about the poor. Stuart Raymond describes them all: the records of charities, of the poor law overseers, of poor law unions, of Quarter Sessions, of bankruptcy, and of friendly societies. He suggests many other potential sources of information in record offices, libraries, and on the internet. “Packed with incredibly useful reference information which no family historian should be without.” —The Essex Family Historian

Book Description
An analysis of the air mast-equipped German U-boats in World War II and Allied countermeasures. During the last year of World War II, the once surface-bound diesel-electric U-boat ushered in the age of “total undersea war.” This was due to the introduction of an air mast, or “snorkel” as it became known among the men who served in Doenitz’s submarine fleet. U-boats no longer needed to surface to charge batteries or refresh air; they rarely communicated with their command, operating silently and alone among the shallow coastal waters of the United Kingdom and across to North America. At first, U-boats could remain submerged continuously for a few days, then a few weeks, and finally for months at a time, and they set underwater endurance records not broken for nearly a quarter of a century. The introduction of the snorkel was of paramount concern to the Allies, who strived to frustrate the impact of the device before war’s end. Every subsequent wartime U-boat innovation was subordinated to the snorkel, including the new Type XXI Electro-boat wonder weapon. The snorkel’s introduction foreshadowed the nearly un-trackable weapon and instrument of intelligence that the submarine became in the postwar world. Total Undersea War answers many long-standing questions about the last year of the war: How and why did U-boats patrol so close inshore? How effective was acoustic and anti-radar camouflage? Why was U-boat wireless communication so problematic? How did U-boats navigate so effectively submerged? What were the health implications of staying submerged for a month or more? What does an accurate snorkel-configuration look like? This previously unpublished historical data is applied to a maritime archaeological case study about how the snorkel-equipped U-869 likely met its demise off the United States’ east coast in February, 1945. The theory that emerges based on a precise understanding of late-war snorkel operations is new and compelling. This exhaustive study, the first of its kind, draws upon wartime documents from archives around the world to re-evaluate the last year of the U-boat's deployment, all its key technological innovations, the evolving operations and tactics, and Allied countermeasures. It is destined to become an authoritative reference on late-war U-boat development for historians and maritime archaeologists alike for years to come. Praise for Total Undersea War “The snorkel's powerful influence during the Battle of the Atlantic is reflected in this riveting book that is filled with action photographs, schematics, and page-turning accounts of the great advantage given to the German navy by this revolutionary piece of equipment.” —Maritime Engineering Journal

Book Description
This compelling book explores Germany’s campaign of unrestricted submarine warfare in World War I, which marked the onset of total war at sea. Noted historian Lawrence Sondhaus shows how the undersea campaign, intended as an antidote to Britain’s more conventional blockade of German ports, ultimately brought the United States into the war. Although the German people readily embraced the argument that an “undersea blockade” of Britain enforced by their navy’s Unterseeboote (U-boats) was the moral equivalent of the British navy’s blockade of German ports, international opinion never accepted its legitimacy. Sondhaus explains that in their initial, somewhat confused rollout of unrestricted submarine warfare in 1915, German leaders underestimated the extent to which the policy would alienate the most important neutral power, the United States. In rationalizing the risk of resuming the unrestricted campaign in 1917, they took for granted that, should the United States join the Allies, German U-boats would be able to stop the transport of an American army to France. But by bringing the United States into the war, while also failing to stop the deployment of its troops to Europe, unrestricted submarine warfare ultimately led to Germany’s defeat. Because US manpower proved decisive in breaking the stalemate on the Western Front and securing victory for the Allies, Sondhaus argues that Germany’s decision to stake its fate on the U-boat campaign ranks among the greatest blunders of modern history.

Book Description
When first published in 1995, this book was hailed as an absolutely indispensable contribution to the history of the Pacific War. Drawing heavily from Japanese sources and American wartime intercepts of secret Japanese radio messages, a noted American naval historian and a Japanese mariner painstakingly recorded and evaluated a diverse array of material about Japan's submarines in World War II. The study begins with the development of the first Japanese 103-ton Holland-type submergible craft in 1905 and continues through the 1945 surrender of the largest submarine in the world at the time, the 5300-ton I-400 class that carried three airplanes. Submarine weapons, equipment, personnel, and shore support systems are discussed first in the context of Japanese naval preparations for war and later during the war. Both successes and missed opportunities are analyzed in operations ranging from the California coast through the Pacific and Indian Oceans to the coast of German-occupied France. Appendixes include lists of Japanese submarine losses and the biographies of key Japanese submarine officers. Rare illustrations and specifically commissioned operational maps enhance the text.

Book Description
The remarkable true story of Dudley “Mush” Morton, the most admired—and feared—submarine commander of World War II Mush Morton was a warrior without peer. At the helm of the USS Wahoo he completely changed the way the submarines fought in the Pacific War. He would relentlessly attack the Japanese at every opportunity, burning through his supply of torpedoes in record time on every patrol. Over the course of only nine months and five patrols, Morton racked up an astounding list of achievements, including being the first American skipper to wipe out an entire enemy convoy single-handedly. Here, for the first time, is the life and legend of a heroic submarine commander who fought the war on his own terms, and changed the course of the undersea war in the Pacific.

Book Description
*Includes pictures *Includes accounts of submarine warfare by sailors on both sides *Includes online resources and a bibliography for further reading *Includes a table of contents "When we went out on patrol we were on our own. There was no one to give us orders how to make the approach, how to attack, how to follow through. It was us against the enemy. We were corsairs in a world that had almost forgotten the word." - George Grider Submarines exercised a decisive impact on the outcome of the Pacific Theater in World War II. The U.S. submarine fleet, largely though not exclusively under the overall command of Vice Admiral Charles Lockwood, strangled the supply lines and shipping traffic of the Empire of Japan. Their commerce raiding crippled both Japan's ability to keep its frontline units supplied and to manufacture the weapons, vessels, and vehicles needed to successfully carry on the struggle. The United States and Japan both produced excellent, high-tech submarines in the context of the World War II era. Japanese I-boats showed excellent seakeeping capabilities and offered the versatility created by their large size, including the ability to serve as motherships for midget submarines or aircraft carriers for scouting aircraft or even specialized bombers. The Type 93 Long Lance and Type 95 torpedoes they carrier packed enough punch to sink capital ships like battleships and carriers at ranges of several miles. American submarines, though smaller, could dive deeply, move quickly, and provide both firepower and survivability. Though their Type XIV and Type XVIII torpedoes could not match the Japanese Type 93, they still gave a lethal punch, particularly after improvements in late 1943. The USS Archerfish demonstrated the deadliness of American submarines to Japanese capital ships also. The submariners of both fleets showed immense courage, daring, and skill in carrying out their duties. Both groups of men exhibited aggression, patriotism, and fighting spirit in equal measure, regardless of the different cultural lenses through which these traits manifested themselves. Both navies successfully produced professional, highly capable submarine officers. The Japanese, however, decided to use their submarines mainly to support a grand fleet action at visual ranges, which never occurred. Instead, the submarines carried out sporadic, uncoordinated attacks and the rest of the time remained on sentry duty or found their time squandered with supply runs and undersea evacuations. The Japanese never corrected these problems - probably due to cultural factors. The rowdy, democratic Americans, suspicious of authority and used to asserting themselves, confronted their commanders boisterously when they felt something was amiss. The torpedo problem nearly caused fistfights between submarine skippers and admirals, yet in the end, the admirals examined and corrected the problem. Though constituting only 1.6% of the total U.S. Navy's tonnage in the Pacific, the submarine fleet inflicted massive losses on the Imperial Japanese Navy and Japan's crucial merchant marine. Submarines sank 55% of the merchant shipping lost, or approximately 1,300 vessels; overall, the Allies sank 77% of Japan's shipping. The submarines also sank 214 Japanese warships, including 82 of 1,000 tons or more - 4 carriers, 4 escort carriers, one battleship, 4 heavy cruisers, 9 light cruisers, 38 destroyers, and 23 submarines - or approximately 30% of the entire Imperial Japanese Navy. The sleek, predatory craft made in the shipyards of Virginia, Wisconsin, or Washington state devastated the naval and freighter assets of the Empire of the Rising Sun out of all proportion to their numbers, at a cost of 42 submarines on "Eternal Patrol." Submarine Warfare in the Pacific: The History of the Fighting Under the Waves between Japan and America during World War II analyzes the underwater fighting between the Allies and Japan across the Pacific theater.

Book Description
A Washington Post Notable Book In March 1941, after a year of devastating U-boat attacks, the British War Cabinet turned to an intensely private, bohemian physicist named Patrick Blackett to turn the tide of the naval campaign. Though he is little remembered today, Blackett did as much as anyone to defeat Nazi Germany, by revolutionizing the Allied anti-submarine effort through the disciplined, systematic implementation of simple mathematics and probability theory. This is the story of how British and American civilian intellectuals helped change the nature of twentieth-century warfare, by convincing disbelieving military brass to trust the new field of operational research.
