US Army Master Sergeant John C Woods acted as an executioner; the equipment, the process of execution, and the construction of the gallows were carried out with the advice and participation of German executioner Johann Reichhart.

Wilhelm Keitel was hanged second, followed by Ernst Kaltenbrunner, Alfred Rosenberg, Hans Frank, Wilhelm Frick, Julius Streicher, Fritz Sauckel, and Alfred Jodl. The last to be executed was Arthur Seyss-Inquart. The executions ended at 2:45 a.m.
