The Wilhelm Gustloff

On 30 January 1945 a former cruise liner left Gotenhafen with refugees, wounded soldiers and navy trainees aboard. That night three torpedoes hit her. The episode follows a ten-year-old boy, a mother of three, a navy doctor and a sailor's family through the sinking and the months after, and asks why no one can say how many died.

I have lost my 3 children and am now completely alone.

    The Road to Tenochtitlán

    About five hundred Spaniards reached Tenochtitlán in November 1519, but they did not walk the road alone. This episode follows the interpreters, the Totonac and Tlaxcalan allies, and the porters who carried the expedition inland, and the people of Cholula who paid for decisions made by others.

How we tell it

No war porn. No glory. Just what it cost.

  1. 01

    The person before the battle

    We start with a name, a role and a moment, not a map arrow. Battles are where these stories happen, not what they're about.

  2. 02

    Numbers over adjectives

    Wounded, surgeons, minutes, miles. Every figure carries its source in the same breath, and where sources disagree, we show you.

  3. 03

    Their words, not ours

    Letters, diaries and testimony are quoted as written and set apart from the narration. A soldier's own words never sound like a script.

Every source on this site carries one of three labels

  • Checked against the source
  • Not yet checked
  • Accounts conflict
How we research history

The Knowledge Base

What the words in the history books meant

27 entries on wounds, disease, exposure, evacuation and supply. Each one is linked to every episode where it matters.

Who makes this

Made by a former Navy FMF corpsman

I served as a U.S. Navy Hospital Corpsman and Fleet Marine Force corpsman with the Marines from 2002 to 2010, including a deployment to Afghanistan. I make this for the medics, corpsmen and veterans who know what the textbooks leave out, and for anyone who wants history told at the level of the people inside it.
