Ganwyd Charles Bernard Davies ar 5 Mehefin 1894. Mynychodd Goleg Llanymddyfri lle'r enillodd glod fel athletwr. Ymddengys iddo chwarae fel canolwr i dîmau Rygbi Abertawe a Chaerdydd yn ogystal a chwarae i'r tîm lleol yng Nghaerffili. Cyn bod rygbi swyddool yn cael ei wahardd yn ystod gweddil y rhyfel, chwaraeodd yn y gêm olaf rhwng Caerffili a'r gelyn lleol, Bedwas. Yn ôl The Caerphilly Journal chwaraewyd y gêm ar 2 Hydref 1914 - 'The meeting at Virginia Park between these near rivals which, under normal circumstances is usually one of the most remunerative fixtures of the season was witnessed by less than 100. Caerphilly fielded only 13 men whist Bedwas included a couple of Caerphillyites. In the first half both sides made strenuous efforts to score and the homesters were rewarded by Reggie Young [a fu farw gyda'i frawd Archie yn 1918] judging to a nicety a cross kick by Strickland and rushing over the line for a try; which was not converted. The second half was a ding-dong nature. C.B. Davies picked up at half way and beating man after man ran through the opposition and scored a really fine try.' Dyna'r cais olaf a sgoriwyd gan un o chwaraewyr Caerfilli tan ar ôl y rhyfel. Cofrestrodd Charles Davies yng Ngholeg Brasenose, Rhydychen, yn Hydref October 1914 gan ymuno â Chorfflu Hyfforddi Swyddogion. Comisiynwyd Lefftenant Davies ac ymunodd â 3 Bataliwn y Royal Dublin Fusiliers ac yn Mehein 1916 roedd yn gwersyllu gerllaw Mailly Wood ar Ffrynt y Gorllewin yn ardal y Somme. Mae Dyddiadur Rhyfel y Gatrawd ar 8 a 9 Mehefin yn cofnodi cyflwr y ffosydd:- '8/6/16 Rain commenced- work cleaning and draining trenches making Lewis Gun emplacements in front of parapet. Draft of 25 other ranks arrived. 9/6/16 Weather still very bad and work held up in consequence. Some overhead cover put up behind front trenches. Reconnoitring Patrol under Lt. C B Davies, LCpl Daly, Pte Dunne and Pte Hayden went out into Nomans land and only Pte. Dunne returned and he was severely wounded.' Danfonwyd teligram at ei fam yn dweud wrthi, "Lieut. C. B. Davies Dublin Fusiliers is missing believed Wounded and prisoner 11 June. Any further reports will be sent on receipt." Bu ymchwiliad i'r hyn a ddigwyddodd i C B Davies, ac o'i wely yn ysbyty Etaples ysgrifennodd Corpral A Green :- ' Lt. Davies went out with a party of men in a raid on the German trenches at Mailly on June 11th...Only Dunn got back. He lived long enough to state that he had seen Davies struggling with a big German in one of the German trenches He died soon after. He was a hard case, and refused to believe he was going to die although being badly wounded in five places. Lt. Davies was a very popular man in the Batt. a very good boxer. It is believed that he was taken prisoner.' Dywedodd Sarsiant Carney:- 'I believe that Mr. Davies was taken prisoner. He was fighting with some Germans and I saw some flashes near him, but do not know if he was hit...I was lucky in hitting on a passage through our wire. We searched the ground afterwards but found no trace of any of these men.' Fodd bynnag, daeth cadarnhad o farwolaeth C B Davies ym mis Medi 1917. Fe'i coffeir yn Queens Cemetery, Bucquoy gan gofeb arbennig i chwech o filwyr o Brydain a gladdwyd ym mynwent Almaenig Miraumont ond dinistriwyd y beddau gan siel ym Mrwydr y Somme.
