The Kaiser's Lost Kreuzer: A History of U-156 and Germany's Long-Range Submarine Campaign Against North America, 1918

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.
