GB & Ire 12½-11½ United States
Great Britain and Ireland's amateurs claimed their third successive Walker Cup win after a rousing comeback on the final day against the United States.
The US needed only three and a half points from eight singles matches on Sunday after maintaining their two point overnight lead in the morning's foursomes.
However, Gary Wolstenholme and Oliver Wilson claimed their second points of the day to level the match.
Michael Skelton and David Inglis registered comfortable wins and Stuart Manley defeated Trip Kuehne by 3&2.
And Nigel Edwards chipped in at 14 and holed a monster putt on 17 to halve his match with Lee Williams.
"I don't know why we leave it so late," winning coach Garth McGimpsey said of his team.
"I was a shattered man yesterday and not in my wildest dreams did I think we could pull it off. They pulled everything out of the fire today. I think we were due a slight bit of luck.
"The American team were a fantastic team who holed a lot of putts in the first three sessions against us. We holed a couple of chips - everything went our way. It had to to win 5½ points out of the singles.
"We had to come out with a fast start. Oliver Wilson and Gary Wolstenholme at one and two got us the start we
needed. Michael Skelton was an absolute bonus. He got the crowd behind them and there was just one cheer after another."
Wolstenholme, playing with a neck strain, and Wilson got the home side off to a great start by hammering top American pair Bill Haas and Kuehne five and four in the foursomes.
But Irish duo Noel Fox and Colm Moriarty were trounced six and five by Brock Mackenzie and Matt Hendrix.
Manley ensured victory for the hosts with a win over Kuehne
American Adam Rubinson missed from under three feet on the final green to give Scots Stuart Wilson and David Inglis a half.
But Welsh pair Edwards and Manley bogeyed the last to end all square with Lee Williams and George Zahringer.
Wolstenholme was accused of playing out of turn in his match as tempers flared.
Kuehne argued that Wolstenholme played out of turn while he and Haas were searching for their ball in gorse.
