Moments across the trial

Rampton cross-examines Irving on the rhyme he wrote for his nine-month-old daughter Jessica

Justice Gray cited this exchange in his April 2000 judgment as direct evidence of Irving holding racist views. The "ditty" passage is one of the most-quoted moments of the trial; the phrase "perverted racist father" is Rampton's, said to Irving's face.

Day 3 — Irving reads the wartime decrypts of SS police-radio traffic into the record from counsel's bench

The intercepts are a foundational evidentiary corpus: SS-police messages that were transmitted over military radio during 1941–1943, intercepted by Bletchley Park, decoded at the time, and released to historians in stages from the 1990s onward. They include the Höfle telegram of 11 January 1943 reporting 1,274,166 arrivals at the four Reinhard sites by 31 December 1942 alone. Irving's decision to introduce them himself — reading them aloud from counsel's bench — left them in the record on his terms, and made them available for cross-examination and judgment without the defence having to formally adduce them.

Day 10 — Irving argues that the four marks on the 1944 aerial photograph of Krematorium II are shadows of tar barrels, not the Zyklon-B introduction chimneys van Pelt's report identifies

This is the peak of Irving's engineering critique. He has the photograph; he has van Pelt; he wants to put it to the witness that the dark marks visible from the air do not align with the chimneys visible from the ground, and therefore cannot be the same objects. Van Pelt's response, walked through across the next sequence of pages, is to produce the construction-period ground photographs that show the chimneys themselves rather than their shadows. The exchange is the closest the trial gets to a single-document Auschwitz argument, and Gray notes in the judgment that "no real substance" attaches to Irving's points against van Pelt's evidence.

Days 9–11 and Day 20 — Irving's published 100,000 figure does not survive cross-examination; he concedes a figure roughly five times higher under questioning

From the 1980s onward Irving's public position was that the Auschwitz death toll was approximately 100,000. He repeated the figure at the 1986 Australia press conference, on which the defence put a recording. By the end of his three-day cross-examination of van Pelt, working from van Pelt's transport-list analysis, Irving had conceded that approximately 500,000 Jews were killed at the camp — five times his published figure, and still well below the figure (~1.1 million) that has stood in mainstream historiography since Piper's 1993 archival work. The concession is one of the most pointedly cited moments of the trial in Gray's judgment.

Day 24 — Irving asks Longerich whether the March 1942 Justice Ministry note is "a key document in the history of the Final Solution"

The Schlegelberger memorandum is the document Irving's anti-order thesis rests on: a 1942 Justice Ministry note in which a subordinate official summarises a conversation in which Hitler is understood to have said the Jewish question should be deferred until after the war. Irving treats the document as decisive. Longerich, the Royal Holloway historian whose principal field is the German persecution of the Jews and Himmler's biography, walks through the document's actual scope (the Mischling question, not extermination) and its position in the surrounding documentary record (in the same period Hitler is approving deportations). The exchange is a clean specimen of what was at stake on the Hitler-knowledge question: whether one document, read in isolation, can overturn a documentary chain of correspondence stretching across two years.

Day 24 — Irving's question to Longerich about reading the Wannsee Protocol

The Wannsee Protocol does not, on its face, use the word killing. The conference, held on 20 January 1942, occurred six months after bullet-killings in the East began, more than a month after Chelmno's first gassing, and during construction of Bełżec. The Protocol's euphemistic register (Sonderbehandlung, Aussiedlung, "natural reduction through labour") is the language all comparable Nazi documents use; it is not coy translation. Irving's question — whether the historian is being asked to read "between the lines" — gestures at a sceptical-empiricist reading that requires every assertion of central direction to be backed by a single edict. Longerich's reading is the contrary: that the lines themselves say what they say in the period's own working vocabulary.
