A match that promised so much became a game of might-have-beens as the first semifinal ended on an empty note.
Wales probably still should have won - they missed three kickable goals and only a lack of composure in the last 20 minutes prevented them from sending a French team home that looked a beaten side.
But the flashpoint - that will be rued for years - was the red card for the inspirational Welsh number seven Sam Warburton in the 18th minute.
The Welsh captain is far from a dirty player, but Irish referee Alain Rolland used the full letter of the law in deciding that his tackle on French winger Vincent Clerc merited a sending off.
Warburton hit the diminutive winger with his full force, elicited cheers from the crowd. He drove him backwards but - maybe as a consequence of the slippery surface - seemed to over balance which caused him to lift Clerc above the horizontal.
