That rude song about Hitler was true, he really did only have one!

AS a light-hearted song, it lifted the nation’s spirits during the darkest days of the Second World War.

Now it seems those singing it were right all along – for Adolf Hitler did indeed only have one b***.

German historian Peter Fleischman of the University of Erlangen, has unearthed the medical notes about Hitler’s deformity.

They were compiled by a doctor after the Beer Hall Putsch in 1923, when Hitler tried to start a revolution in Munich.

The coup attempt was stopped by the army and police, and Hitler fled. He was arrested two days later and examined at Landsberg prison, according to the documents.

The notes, compiled by medical officer Dr Josef Brinsteiner, said Hitler was ‘strong and healthy’, weighing 78kg. However, they recorded that he suffered from ‘right-side cryptorchidism’, a condition in which a testicle has not descended properly. It usually affects young boys during the period when their testicles are supposed to descend.

The notes are believed to be the first official documentary evidence of Hitler’s deformity. Suggestions that he had lost a testicle at the Battle of the Somme had existed for decades, and were given some credence in 2008 when an account from a battlefield doctor emerged, suggesting he had seen evidence of the injury.

German First World War medic Johan Jambor told his priest he blamed himself for saving the young soldier’s life after finding him screaming for help.

In a documented conversation during the 1960s, he described his encounter with the future fuhrer.

Notes taken by the priest read: ‘His abdomen and legs were all in blood. Hitler was injured in the abdomen and lost one testicle. His first question to the doctor was: “Will I be able to have children?”.’

Some historians have disputed the claims, noting that other medical reports, including those by Dr Theodor Morell, Hitler’s doctor, never mentioned the deformity.

The origin of the song, sung to the tune of the Colonel Bogey March, is unclear, but some claims suggest it was written by a British Council publicist to humiliate the Nazi leader and his cronies.

It caught on among soldiers and civilians alike, and endured long after the Second World War had ended.
