Battle of the Somme: From Adolf Hitler to JRR Tolkien – the battle's most famous combatants

The 20th century's worst dictator, future British politicians and a father later send to a concentration camp by the country he fought for were among those who served during the Battle of the Somme.

Here are some of those who fought one of the world's bloodiest battles and lived on to become famous or infamous.

Adolf Hitler: The megalomaniac Nazi dictator was injured fighting for the German Empire on the Somme. Over the years there has been speculation that he suffered a wound to his genitals as well as the leg wound suffered while serving with a Bavarian unit, which gave rise to the legend that he only had one testicle. In a postcard unearthed in 2012 the then 27-year-old soldier wrote of his intention to "report voluntarily for the field immediately" from the hospital in Munich where he was recovering.
