England captain Chris Robshaw revealed the thought process within the side after turning down a crucial kick at goal late on against Wales.
The Rugby World Cup hosts went on to lose after Dan Biggar's seventh penalty clinched a shock victory for Wales at Twickenham after trailing for the majority of the match.
"That call comes down to myself. I spoke to the kickers on the pitch and we decided we wanted to go for the win," Robshaw said.
"It was a tough kick, we weighed up the options, and the two driving mauls before we made some good ground. We thought if we got in that position we could go for the win.
"If it's an easier kick then you look at different options, but it wasn't.
"Now it's about the reaction and the character of the squad. It hurts like hell at the moment. We feel we've let a lot of people down today and the people who have come to support us.
"It's about what happens next and a huge game against Australia. We'll be pretty gutted and devastated tonight but you have to move on pretty quickly.
"The crowd gave us a huge lift with the number of white shirts there. We feel we let them down today, we let a lot of people down, and we didn't finish the game out how we wanted to.
"This is where we find out what we're about."
England head coach Stuart Lancaster was quick to congratulate Wales on their win while underlining his side's need to refocus before their must-win clash against Australia.
"Well done to Wales, it was a great game of rugby between two competitive sides," he said.
"We're obviously absolutely devastated at losing the game having been in a position where we were playing so well and leading on the scoreboard. A world-class goalkicker in Dan Biggar kept them in the game and they got the win, so well done to them.
"There's no doubt that it's knockout rugby now. Wales have to play Fiji and Australia, but our game with Australia is now knockout rugby. Two teams go through and teams in the past have lost and then made it. I said to the boys that now everything has to go into beating Australia.
"I know the boys are gutted but collectively I think there's more frustration at the number of penalties we gave away. We talked a lot about the discipline at the breakdown and how are referees are tight on that, which was ultimately the difference.
"I thought the team played well, especially the first half performance which was excellent really. Owen Farrell had a great game, there was a lot made about that but I trusted the team and selection.
"It's hurt us tonight but we have to roll our sleeves up pretty quick and get ready for Australia."
