Churchill's Ministry of Ungentlemanly Warfare by Giles Milton

Milton engagingly re-creates some of these spectacular operations, including the destruction of the Pessac, France, transformer station (Operation Josephine B), the dismantling of the Normandie Dock, where the formidable Tirpitz was moored, and the strike on the Norsk Hydro station in Norway, which eliminated the possibility of Hitler using heavy water for atomic weapons. Using unconventional, powerful new inventions of destruction, such as a “monstrous hydraulic digger” engineered by Cecil Clarke, the so-called limpet mine, L-Delay fuse, and the anti–U-boat Hedgehog mortar, the unit employed effective sabotage against the German war machine.

Led by the canny Scotsman and former Indian Army officer Colin Gubbins and the engineering genius Millis Jefferis, this group of “pirates” was carefully selected for their mental and physical toughness for under-the-radar guerrilla operations to trip up the swiftly advancing Germans in Norway, France, and, potentially, Britain. Prolific British author Milton ( When Hitler Took Cocaine and Lenin Lost His Brain: History's Unknown Chapters, 2016, etc.) manages to offer a fresh take on the undercover work of a small specialty unit of the British War Office, begun as MI(R) before becoming the Special Operations Executive, or known simply as Baker Street. An elegant presentation of Winston Churchill’s special guerrilla operations force, which consistently met the dirty exigencies of war.
