They served, among others, Major General Henning von Tresckow and Fritz-Dietlof von der Schulenburg in the regiment. All together, I.R. 9 supplied more plotters for the attempted assassination of German dictator Adolf Hitler and abortive coup d"état than any other regiment in the Wehrmacht.

On 5 March 1945, the German "People"s Court" (Volksgerichtshof) sentenced him to death for his part in the July 20 Plot. He was put to death the same day at Plötzensee Prison in Berlin.
