“ . . . until now how the Navy managed to instantaneously move from the overt legal restrictions of the naval arms treaties that bound submarines to the cruiser rules of the eighteenth century to a declaration of unrestricted submarine warfare against Japan immediately after the attack on Pearl Harbor has never been explained. Lieutenant Holwitt has dissected this process and has created a compelling story of who did what, when, and to whom.”—The Submarine Review “Execute against Japan should be required reading for naval officers (especially in submarine wardrooms), as well as for anyone interested in history, policy, or international law.”—Adm. James P. Wisecup, President, US Naval War College (for Naval War College Review) “Although the policy of unrestricted air and submarine warfare proved critical to the Pacific war’s course, this splendid work is the first comprehensive account of its origins—illustrating that historians have by no means exhausted questions about this conflict.”—World War II Magazine “US Navy submarine officer Joel Ira Holwitt has performed an impressive feat with this book. . . . Holwitt is to be commended for not shying away from moral judgments . . . This is a superb book that fully explains how the United States came to adopt a strategy regarded by many as illegal and tantamount to ‘terror’.”—Military Review

Unrestricted Warfare reveals the dramatic story of the harsh baptism by fire faced by U.S. submarine commanders in World War II. The first skippers went to battle hamstrung by conservative peacetime training and plagued by defective torpedoes. Drawing extensively from now declassified files, Japanese archives, and the testimony of surviving veterans, James DeRose has written a fascinating account of the men and vessels responsible for the only successful submarine campaign of the war. They clearly charted a new course to victory in the Pacific. ADVANCE PRAISE FOR UNRESTRICTED WARFARE "James DeRose has done an excellent job-- surprisingly so, in view of his lack of true WWII submarine experience. He obviously contacted everyone he could find who served on one of the three boats he concentrated on, and he read, as well, everything he could find that was written about them. . . . DeRose shines by his interpretation of events as the Japanese must have seen them. . . . His reconstruction of how Wahoo came to her end may well be pretty close to correct. . . . He does the same with Tang."-CAPTAIN EDWARD L. BEACH, USN author of Submarine! and Run Silent, Run Deep "An outstanding addition to the literature of the Silent Service. . . . The depth of research is wonderful. . . . This is fine history . . . that rivals Blair's Silent Victory."-PAUL CROZIER, sitemaster, "Legends of the Deep" (www.warfish.com) Web site on the USS Wahoo "I knew all of the book's main characters quite well. . . . I am also completely familiar with submarine operations in the Pacific. With that background I couldn't fail to thoroughly enjoy DeRose's book. It is well written and has the right feel."-CHESTER W. NIMITZ JR., rear admiral, USN (Ret.) "Sail with American submariners into tightly guarded Japanese home waters; undergo the horror of a depth charge attack; experience the thrill of victory with some of the U.S. Navy's ace submarine skippers. All this--and much more--is contained in James F. DeRose's compelling Unrestricted Warfare. No one interested in the naval side of World War II should be without it."-NATHAN MILLER author of War at Sea: A Naval History of World War II

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.

New naval history of the First World War which reveals the contribution of the war at sea to Allied victory.

A deeply researched and engaging account of the use of U-Boats in the First World War. The focus touches on both diplomatic and economic aspects as well as the tactical and strategic use of the U-boats. The book also examines the role played by US president Woodrow Wilson and his response to American shipping being sunk by U-boats and how that ultimately forced his hand to declare war on Germany.

#1 NEW YORK TIMES BESTSELLER • From the bestselling author and master of narrative nonfiction comes the enthralling story of the sinking of the Lusitania “Both terrifying and enthralling.”—Entertainment Weekly “Thrilling, dramatic and powerful.”—NPR “Thoroughly engrossing.”—George R.R. Martin On May 1, 1915, with WWI entering its tenth month, a luxury ocean liner as richly appointed as an English country house sailed out of New York, bound for Liverpool, carrying a record number of children and infants. The passengers were surprisingly at ease, even though Germany had declared the seas around Britain to be a war zone. For months, German U-boats had brought terror to the North Atlantic. But the Lusitania was one of the era’s great transatlantic “Greyhounds”—the fastest liner then in service—and her captain, William Thomas Turner, placed tremendous faith in the gentlemanly strictures of warfare that for a century had kept civilian ships safe from attack. Germany, however, was determined to change the rules of the game, and Walther Schwieger, the captain of Unterseeboot-20, was happy to oblige. Meanwhile, an ultra-secret British intelligence unit tracked Schwieger’s U-boat, but told no one. As U-20 and the Lusitania made their way toward Liverpool, an array of forces both grand and achingly small—hubris, a chance fog, a closely guarded secret, and more—all converged to produce one of the great disasters of history. It is a story that many of us think we know but don’t, and Erik Larson tells it thrillingly, switching between hunter and hunted while painting a larger portrait of America at the height of the Progressive Era. Full of glamour and suspense, Dead Wake brings to life a cast of evocative characters, from famed Boston bookseller Charles Lauriat to pioneering female architect Theodate Pope to President Woodrow Wilson, a man lost to grief, dreading the widening war but also captivated by the prospect of new love. Gripping and important, Dead Wake captures the sheer drama and emotional power of a disaster whose intimate details and true meaning have long been obscured by history.

In A Scrap of Paper, Isabel V. Hull compares wartime decision making in Germany, Great Britain, and France, weighing the impact of legal considerations in each. She demonstrates how differences in state structures and legal traditions shaped the way the three belligerents fought the war. Hull focuses on seven cases: Belgian neutrality, the land war in the west, the occupation of enemy territory, the blockade, unrestricted submarine warfare, the introduction of new weaponry, and reprisals. A Scrap of Paper reconstructs the debates over military decision-making and clarifies the role law played—where it constrained action, where it was manipulated, where it was ignored, and how it developed in combat—in each case. A Scrap of Paper is a passionate defense of the role that the law must play to govern interstate relations in both peace and war.
