World War I

During the Great War, Chateau de Bertangles served as headquarters of the British General Staff, for the Battle of the Somme in 1916, and then to the Australian General Staff under the command of General John Monash.

Sir John Monash

It was at the Chateau de Clermont-Tonnerre that the decisive attacks of the Battle of Amiens were conceived, leading to the “Black Day of the German Army” and to victory a few months later.

On August 12, 1918, King George V knighted General Monash.

The first time a British monarch had honoured a commander in such a way in 200 years

The ceremony takes place in presence of all the command on the steps of the castle. (Movie here)
