Nazi Conspiracy and Aggression (NCA)

Published between 1946 and 1948 by the Office of United States Chief of Counsel for Prosecution of Axis Criminality, NCA is a collection of documentary evidence and guide materials prepared by the American and British prosecuting staffs for presentation before the International Military Tribunal at Nurnberg (Nuremberg), Germany. Because the binding on the original hardcover edition is red, they are sometimes referred to as "the red volumes" (the IMT series are "the blue volumes," and the Doctors' Trials series are "the green volumes").

The contents consist of official papers in archives of the German government and the Nazi Party, diaries and letters of prominent Germans, captured reports, etc. There are six folding charts inserted. This collected documentation is more complete than any official record or transcript of the procceedings, because at the outset of the trial the Tribunal ruled that it would treat no written evidence unless read in full in court. For this reason, the documentation gathered was trimmed considerably for presentation in court. In this collection, the documents are reprinted in their entirety, which makes NCA the most complete and detailed publication of the evidence prepared for the trial.
