[Felix C]

Translated Otto Hersing's memoir and it is available in English. Usual places. He is the celebrated submarine commander who sank the first ship with a torpedo, HMS Pathfinder in 1914, and later two English battleships off Gallipoli,-HMS Triumph and Majestic,  a French cruiser and a few dozen other vessels including a convoy of Dutch merchant ships causing a diplomatic incident with the latter.

A quick read and interesting look at the Revolution of 1918.
