He is also notable for having produced the oldest contemporary sketch of a camp crematorium, also ignored by historians for decades[4] until the 1987 publication of Le Monde juif by Georges Wellers [fr].

A few days later, a friend informed him that a young General De Gaulle was continuing the war in England, and Rogerie resolved to join him.

After the Allied landings in North Africa in November 1942, he sought to join the Free French Forces led by Charles de Gaulle via Spain and the southern Mediterranean Sea.

[6] Through a colleague, he found a source and obtained some counterfeit identity papers, but they were of poor quality, and on 3 July 1943, at age 21, he was arrested by the Gestapo in Dax, along with two other friends.

He was imprisoned, and held by the Gestapo in Biarritz, Bayonne, Bordeaux and Compiègne before being deported to the camps.

Between Memory and Oblivion published in 1992, Annette Wieviorka asks if Rogerie meant the Majdanek camp in the outskirts of Lublin.

He self-published it in 1945 under the title "You Win By Living" (Vivre c'est vaincre) with a print run of 1,000 copies using monies he received as back salary.

This graphic was credited by Georges Wellers [fr] as being the oldest of its kind and highly accurate.

[11] The fact of having drawn it immediately after liberation became a source of relief to Rogerie, because what he lived through later seemed so incredible, that he sometimes wondered if it was possible.

"The deportees try to recount it—actual historical facts, but unimaginable—but how to convey the cold, the hunger, the beatings, the suffering, the cries, the howling, the shrieks, the fear, the fatigue, the filth, the stink, the promiscuity, the endlessness, the poverty, the disease, the torture, the horror, the hangings, the gas chambers, the deaths?

"[12] Rogerie matriculated as an officer candidate in Saint-Cyr, the French West Point or Sandhurst, in 1946.

[6] He drew a clear distinction between deportation and persecution (of Jews and Gypsies) on the one hand, and that of repression (of Resistance members) on the other.

[6] He gave testimony about life in concentration camps in speeches to academic establishments, and on CD and on DVD.

On 16 January 2005, he testified about his experiences along with Simone Veil at the Paris city hall, on the occasion of the commemoration of the liberation of Auschwitz.
