Alastair Cook credited a "kick up the a***" from coach Trevor Bayliss for England's stunning victory charge in Johannesburg.
The third Test against South Africa lay perfectly poised at lunch on day three, with South Africa 16 without loss in their second innings and setting about building a lead.
But Bayliss issued an animated call to arms at the interval and watched on as Stuart Broad produced another magical spell for his seam bowling scrapbook.
Broad tore apart the Proteas top order in a spell reminiscent of his Ashes heroics at Trent Bridge, finishing with six for 17 as the hosts slumped to 83 all out.
The game - and the series - was settled there and then, with England chasing down a target of 74 for a seven-wicket victory and an unassailable 2-0 advantage.
Broad, at his mercurial best, was the obvious focal point but Cook praised the usually taciturn Bayliss for his fiery address.
"Trev gave us a kick up the a*** at lunch," he said.
"Rather than sulking about it the lads looked at themselves, led by Broady, and I think there was a real intensity in the field for that two-hour session.
"It was a realisation from a guy that doesn't say too much that this is the time: if you want to win the series then you've got an opportunity.
"It seemed to work so well done Trevor. It really helped."
Broad left the field with an impressive haul - his best overseas figures, a man-of-the-match award, a first series win over South Africa and third place on England's all-time wickets list overtaking Bob Willis.
His 15th five-wicket haul was another fine example of his ability to alter the course of a Test match when the mood takes him, and he felt he owed the team a display having struggled with a virus on day one.
"I was frustrated from the first innings, I was a little bit ill and I didn't bowl very well," he admitted,
"But a bit of experience tells you now is the time to step up and make something happen. I felt in good rhythm today, for sure.
"That was the sort of wicket as a seam bowler you'd like to take around everywhere. It offered good movement in the air and off the deck and good bounce.
"When you get the opportunity to bowl on a wicket like that and feel in a good rhythm you've really got to take your chance.
"The most important wicket was actually the first one, making the breakthrough with the newer, harder ball. That gave the team confidence that we could do something special.
"Any time you win a Test match anywhere it is special but to beat South Africa for the first time in a Test series and to do it away from home is very special."
Cook was full of praise not just for his match-winner, but also the rest of his side.
Joe Root's 110 was just as important in the context of a low-scoring match, Jonny Bairstow had another impressive outing and Ben Stokes continued his fine all-round series.
"It's pretty special feeling and I'm looking forward to getting back in the changing room to spend some time with a group of guys who've done something very special," he said.
"It really has been a squad effort. It's a real privilege to lead this group at the moment. They're desperate to do well and enjoying each other's success.
"I know it's a bit cliched and it's easier when you're winning but there's a good team spirit between these guys."
And as for Broad: "It's a privilege to captain him. When he gets on a roll like that you just let him go."
