There were 13 Welsh rugby internationals who lost their lives in World War One. But who were they?
Born in 1886 in Maesteg, Dai Watts played for the town side but his Wales career, which only started in January 1914, was cut short by the outbreak of the war.
He joined the King's Shropshire Light Infantry and as a corporal was killed in action in Bazentin Ridge in France in 1916, aged 30.
Rugby historian Gwyn Prescott talks about his career and war service.
