Unaware that he had been relieved of command, Dollmann was nonetheless worn out and stressed. He died on 29 June 1944. The exact circumstances of the death of Dollmann remain controversial. Some sources say he suffered a heart attack, while others claim he committed suicide by taking poison. In 1973, Dollmann's last chief of staff Lieutenant General Max-Josef Pemsel, wrote that on 29 June at around 3:00 am in the morning, Dollmann bid farewell to his staff and committed suicide in his command post. In 2003, a theory was put forward that like Rommel, Dollmann was forced to commit suicide by Hitler. He was buried in France on 2 July 1944, where the field marshals Rundstedt, Rommel and Hugo Sperrle were present. On the same day, he received posthumously the Knight's Cross of the Iron Cross with Oak Leaves. Later, Hitler delivered a laudatory obituary on behalf of Dollmann.
