Charles Caldwell Sills was born in London on 24 December 1893 to George and Alice Stills who moved to Coed Maes (presumably a house name?), Oakham, and educated at Oakham School between 1905 and 1912. After leaving school he entered the Royal Military College at Sandhurst in 1912. He was gazetted as Second Lieutenant in the 1st Battalion of the South Wales Borderers in September 1913. Charles went to France with the 1st Division of the British Expeditionary Force and took part in the battles of Mons, the Marne, and the Aisne. He was killed on 26 September 1914, near Vendresse, while his battalion was trying to repel a strong German attack on its trenches. The records state that a German battalion attacked in front of the 1st South Wales Borderers and penetrated the line at one point but were driven back. The Germans lost very heavily, eighty of them killed on the very edge of the trench. The Borderers also suffered severely, seven officers and 182 men, half of whom were killed. Charles has no known grave and is remembered on La Ferte-Sous-Jouarre Memorial in France. At school he had been a successful athlete, captain of the cricket eleven in 1911 and 1912, and was also in the rugby fifteen. He won the junior and senior Fives Challenge Cups twice each. At Sandhurst he was a double Blue in 1913 for the high jump and cricket. When at Aldershot he played cricket and rugby and a member of the MCC. He is remembered on Oakham's war memorial and in Oakham School Chapel.
