In the aftermath of the war Knight proposed to the War Artists' Advisory Committee the Nuremberg war crimes trials as a subject. The Committee agreed, and Knight went to Germany in January 1946 and spent three months observing the main trial from inside the courtroom. The result was the large oil painting, "The Nuremberg Trial". This painting departs from the realism of her wartime paintings, in that, whilst apparently realistically depicting the Nazi war criminals sitting in the dock, the rear and side walls of the courtroom are missing, to reveal a ruined city, partially in flames.
