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.

The "Second Happy Time" was the informal name given to the phase of the battle of the Atlantic when German U-boats attacked both merchant and U.S. naval vessels along America's east coast. With tankers burning and petrol rationing in New York City, the U.S. Navy seemed powerless to stop the deprivations of Hitler's marauding U-boats. Ken Brown seeks to explain how the United States responded to these deadly assaults and looks at the steps that the Navy Department took to train the men, harness the scientists, and make the organizational changes that were required to defeat the German threat.

When the Fuhrer sent U-boats to America waters in World War Two, he was repeating a strategy that the Kaiser had tried a generation earlier. Long neglected in the annals of military history is the first attempt to employ a fleet of undersea warships to help achieve world domination. While the Kaiser's surface navy was as ineffective against his enemies as the Fuhrer's surface navy, his use of German submarines, or U-boats, afforded a tactical advantage that was unprecedented in naval warfare. The Kaiser's unterseeboote took a great toll on the world's merchant vessels. The volume in hand is the first of its kind to compare Allied action reports with the deck logs and war diaries of German submarine commanders. These bipolar sources permit a true and accurate assessment of U-boat efficacy, while dispelling erroneous notions about the impact of submarine warfare against staunch American defenders. U-boats torpedoed and shelled harmless fishing vessels, plodding windjammers, and unarmed steamships. They laid mines off U.S. harbor approaches. They left sailors stranded hundreds of miles from shore without adequate food and water. They killed men and women indiscriminately. They took prisoners of war. One U-boat lobbed shells onto a beach on Cape Cod, Massachusetts. This was the first time since the War of 1812 that a foreign country attacked the American mainland. This is the trenchant story of U-boat aggression and American defiance in the Great War of atrocities, when people perished at sea or suffered incredible privation in their struggle to survive.

“A comprehensive look at the German submarine tanker program during World War II . . . engaging.” —The NYMAS Review During the Second World War the Germans developed a specially adapted U-boat oil tanker with two aims. First, by refueling the attack U-boat fleet their range of operations and duration of patrol could be significantly increased. Secondly, these underwater tankers were far more likely to avoid detection than surface support ships. The submarine tankers, affectionately known as “Milk Cows,” were regarded by both the Germans and the Allies as the most important element of the U-boat fleet. Allied forces had orders to attack the tankers first whenever a choice was presented. Until late 1942 the German Milk Cows operated with great success and few losses. But from 1943 onwards the German rendezvous ciphers were repeatedly broken by the Allies and losses mounted rapidly. The Milk Cows were highly vulnerable during the lengthy refueling procedure as they lay stationary on the surface, hatches open. By the end of the war virtually every tanker had been sunk with severe loss of life. The story of this critical campaign has been thoroughly researched by the author and is told against the background of changing U-boat fortunes. “The author is to be congratulated on his research and writing such a thorough and readable account of such an interesting subject.” —Windscreen Magazine, Military Vehicles Trust “Readers will be fascinated not just by the mainstream replenishment work but also by the book’s accounts of German submarine operations far afield.” —Navy News

As was the case in World War II, one of the greatest threats to Britain during World War I was the German U-boat menace. This book traces the development of the U-boat threat from the Brandtaucher, designed by Wilhelm Bauer, the father of the German submarine arm, in 1850, through to the commissioning of Germany's first U-boat to go into service, the U-1, in 1906. It then covers the main types of World War I U-boat, detailing the operational history of the U-boat service in depth, with a particular focus on the campaigns in the Atlantic and Mediterranean, as well as the slow build up of anti-submarine measures by the allies.

In the final year of World War I, Germany made its first attempt to wage submarine warfare off faraway shores. Large, long-range U-boats (short for unterseeboot or "undersea boat") attacked Allied shipping off the coasts of the U.S., Canada and West Africa in a desperate campaign to sidestep and scatter the lethal U-boat defenses in European waters. Commissioned in 1917, U-156 raided commerce, transported captured cargo and terrorized coastal populations from Madeira to Cape Cod. In July 1918, the USS San Diego was sunk as it headed into New York Harbor--the opening salvo in a month-long series of audacious attacks by U-156 along the North American coast. The author chronicles the campaign from the perspective of Imperial Germany for the first time in English.

The submarine was one of the most revolutionary weapons of World War I, inciting both terror and fascination for militaries and civilians alike. During the war, after U-boats sank the Lusitania and began daring attacks on shipping vessels off the East Coast, the American press dubbed these weapons “Hun Devil Boats,” “Sea Thugs,” and “Baby Killers.” But at the conflict’s conclusion, the U.S. Navy acquired six U-boats to study and to serve as war souvenirs. Until their destruction under armistice terms in 1921, these six U-boats served as U.S. Navy ships, manned by American crews. The ships visited eighty American cities to promote the sale of victory bonds and to recruit sailors, allowing hundreds of thousands of Americans to see up close the weapon that had so captured the public’s imagination. In America’s U-Boats Chris Dubbs examines the legacy of submarine warfare in the American imagination. Combining nautical adventure, military history, and underwater archaeology, Dubbs shares the previously untold story of German submarines and their impact on American culture and reveals their legacy and Americans’ attitudes toward this new wonder weapon.
