Conor Murray celebrated an "incredible" victory over South Africa after Ciaran Frawley's heroics sealed a 25-24 victory over the Springboks.
Reigning world champions South Africa lost to Ireland on home soil for just the second time as Frawley knocked over a drop-goal with the final kick of Saturday's Test in Durban.
It capped a stunning comeback for Ireland, who trailed 16-6 at half-time.
Remarkably for such a high-scoring encounter, there was only one try, with Murray going over for Ireland, while Handre Pollard converted eight penalties for South Africa.
The day belonged to Frawley, though, as he nailed two drop-goals to condemn South Africa to a first defeat at Kings Park since 2016, ensuring the two-Test series was drawn.
"Incredible," Murray told Sky Sports. "Just to come here, in the world champions' backyard and we knew it would be tough and it was last week and it was again today.
"South Africa don't lose easy and they find a way. It's so frustrating at times to play against. We believed in ourselves, coming into South Africa's backyard is always going to be a big challenge and I think we can be proud.
"Last week hurt, it was a tough defeat and to turn up this week, we knew we were getting a break at the end of the week and the boys turned up and committed to this week."
Frawley was equally as delighted.
"It's mental," he said. "This place is a fortress and it's so loud. The game was back and forth but the boys dug in deep. We were in our own half and managed to get up, we're delighted."
South Africa have lost just their second Test match in the space of 14, with the Springboks seeing a six-match winning run come to a close.
Their only other loss during that run came against Ireland at last year's World Cup.
Springboks captain Siya Kolisi told Sky Sports that his team were always up against it despite taking that big lead.
"In the first half the intensity and the physicality they [Ireland] were in charge of that definitely and we were just playing catch-up," he said.
"We weren't as intense as we were last week and they were dominating us and that was the big change from last week."
The victory saw Andy Farrell celebrate his 50th Test in charge of Ireland in style.
Farrell is only the fourth Irish men's coach to hit the half-century milestone, after Declan Kidney (53), Joe Schmidt (76) and Eddie O'Sullivan (78). He has won 40, with his win rate being the highest of any Ireland coach to have taken charge of at least three Tests.
