I have just seen a Brigadier-General RH Davies on a WWI memorial. I looked him up and was a tad surprised to see (albeit on Wikipedia): This led to him being offered command of 6th Brigade, a regular infantry brigade of British troops, in 1910; he was the first colonial officer to hold such a position. In the summer of 1914 the brigade was mobilised with the British Expeditionary Force, and he commanded it at the Battle of Mons and the First Battle of the Aisne before being invalided back to England due to exhaustion. He was given command of the newly formed 20th (Light) Division, which he took to France in 1915, but was relieved of command early in 1916. After a period in command of a reserve centre in Staffordshire, he was sent to hospital suffering from both mental and physical ill health, and committed suicide in May 1918. Given the stigma at the time of suicide I'm especially surprised he's on the memorial.
