A try from Gareth Davies, a pressure penalty from Dan Biggar and Chris Robshaw turning down the chance of a draw all culminated to see Wales defeat England at Twickenham.
Despite suffering numerous injuries in the game, the Welsh came out on top. They now lead Pool A on nine points with their injury hit squad facing Fiji on Thursday.
Here's how the many Irish viewers on Twitter reacted to the victory for Warren Gatland's side.

It wasn't just the decision to go for touch, that entire second half was a bottle by England.

Incredible comeback by Wales. And a match for the ages. They showed more courage then England and risked more to win it. Magnificent.

England's bench was useless. Sam Warburton and Alun-Wyn Jones have my eternal admiration. Late pen against Warbs was wrong call!
