At the start of the 2013 Six Nations Championships England were favoured to win by many pundits after they beat the world champion New Zealand team in December 2012.
[1] In contrast defending champions Wales had suffered seven consecutive defeats (4 versus Australia) and were without their regular head coach Warren Gatland.
[12] Wales won their round four clash against Scotland 26-13 and in the process achieved a record fifth consecutive away win in the Six Nations.
[16] England were slight favourites heading into the game due to their unbeaten run,[17] although Wales had the advantage of a more experienced side and playing at home in the Millennium Stadium.
[22] At half time Wales had just a 9-3 lead, with three penalties to fullback Leigh Halfpenny against one from England's Owen Farrell.
The first 20 minutes of the second half saw Wales score points through a try to winger Alex Cuthbert, and another penalty goal to Halfpenny.
Wales fly half Dan Biggar dropped a goal, which was then followed by a second try to Cuthbert in the 66th minute to put the game beyond England.
[23][24] Wales coach Rob Howley described the victory as a better achievement than their 2012 Grand Slam[25] and Welsh captain Sam Warburton described the win as the "best moment" of his career.
