After the war ended the OSS conducted an investigation into "Cicero", interviewing key German players including Moyzisch. It was postulated that of the intelligence conveyed by "Cicero" to the Germans, the most notable information came from Knatchbull-Hugessen's notes, particularly regarding diplomatic efforts with the Turkish government. Many of the other documents were considered by Ostuf Schuddekoft, head of the British section of Amt VI of the 11 departments of Hauptamt Volksdeutsche Mittelstelle, to be too old to be of much value to the Germans.
