The mood of the full-back, his Welsh team-mates and the nation changed from pain to unbridled joy within seconds of the final whistle in Zenica.
Bosnia & Herzegovina won the penultimate qualifying match in Group B 2-0 but Israel, who could still have matched Wales' total, lost 2-1 at home to Cyprus.
That means Wales qualify automatically for the Euro 2016 Finals in France next summer - the first time the country has made it to the Euro finals and their first appearance in the finals of a major tournament since the World Cup in 1958.
Speaking to us from Zenica on Saturday night, Ben told us how it felt when the Israel scoreline filtered through - and he was part of Welsh football history.
"It was an incredible feeling, amazing, it's hard to find the words to describe it," said Ben, who earned his 16th cap and completed the 90 minutes.
"It wasn't the performance we wanted and disappointed to lose our first match in qualifying but that soon changed. We were delighted when we heard the Israel score come through.
"It's one of the best moments of my career. This is something we've worked towards for a long time and to finally get there is a special, special feeling."
Ben and Wales will now complete their qualifying campaign against Andorra back in Cardiff on Tuesday night.
He will be joined in the finals by our Belgian quartet of Toby Alderweireld, Nacer Chadli, Mousa Dembele and Nacer Chadli after Belgium secured a top two place in Group B with a 4-1 win in Andorra.
