within one point of beating South Africa in a 7–6 defeat in 1912. But no Cardiff players were selected for another Lions tour for the next sixteen years, and they would not become Welsh champions again for the best part of three decades. Between the wars The First World War certainly had some effect on the club – Johnnie Williams died in the first weeks of the Battle of the Somme, and many other players returned wounded or simply too old to play rugby. Cardiff were forced to turn to younger talent for their team. Jim Sullivan was a prime example of this, making his first appearance for Cardiff at the age of 16 in October 1920, and went on to make 38 appearances over the rest of the season. In December 1920, just after his 17th birthday, he became the youngest player to ever appear for the Barbarians. However, in June 1921 he signed for professional rugby league club Wigan, beginning a new trend of Welsh union players "going north" to play rugby league. Cardiff rugby finally managed a revival of some sort in the 1930s. Scrum-half Howard Poole, although never capped for Wales, was selected to play for the Lions in 1930, as was Ivor Williams in 1938. The club also won their first unofficial Welsh championship for 28 years in 1937, and managed to retain the title in 1938 and 1939, before the start of the Second World War. After the Second World War After the resumption of regular rugby, Cardiff beat Australia 11–3 on 21 November 1947, captained by scrum-half Haydn Tanner and were also unofficial Welsh champions in 1947/48, when Bleddyn Williams set a club record of 41 tries in one season, and 1948/49, when the Blue and Blacks went completely unbeaten against Welsh opposition, only Swansea and Newport succeeding in salvaging draws. The club had a fantastic record against Newport during these years, going 15 games unbeaten against them between 1946 and 1950. Cardiff players helped Wales win their first Grand Slam in nearly forty years in 1950, and later that year supplied five players to the Lions for the first time later that year. The five were fly-half Billy Cleaver, prop Cliff Davies, centre Jack Matthews, scrum-half Rex Willis and Bleddyn Williams, the "Prince of Centres". Williams captained the Lions in the third and fourth Tests against New Zealand. Wales won another Grand
