Unknown Enemy: The Hidden Nazi Force That Built the Third Reich Hardcover – November 11, 2025

The harrowing true story of Organisation Todt, the builders-turned-killers at the center of the Nazi war machine.Adolf Hitler described the Organisation Todt as “the greatest construction organization of all time.” It was from this organization, headed by Albert Speer, that Hitler enlisted the nation's leading engineers and architects to build his empire of dreams. In time, it became a key partner to the SS and the Wehrmacht and led to the deaths of millions. Unknown Enemy reveals the full extent of the OT and its long arm across Europe and the Reich. In wartime, its operations relied mainly on Germany's slave labor system, the largest exploitation of foreign labor since the end of the Transatlantic Slave Trade. Charles Dick takes us inside the OT's vast building projects throughout German-occupied Europe, from the Arctic circle to the Balkans, to tell the story of how engineers and builders-so-called “ordinary men”-perpetrated some of the gravest war crimes under its banner.

Drawing on extensive new research, first-person accounts and survivor testimony, Unknown Enemy finally unearths its dark story. Read more
