^Adolf Ax's nomination shows no indication that the request had been processed or granted, not even an entry date is noted. The nomination list indicates that the request was filed on the 28 April 1945. A Heerespersonalamt (HPA—Army Staff Office) nomination with the number 5092 had been created. The nomination, according to the book "Verliehene Ritterkreuze" (Awarded Knight Crosses), was forwarded to the HPA on 25 April 1945. No proof exists that the Knight's Cross was awarded. The Order Commission of the Association of Knight's Cross Recipients (AKCR) processed this case in 1981 and decided: Knight's Cross yes, 9 May 1945. Ax was member of the AKCR.
