Katie Taylor set the record straight against her nemesis Delfine Persoon in a gruelling encounter in the Matchroom Fight Camp in London.
The Bray fighter survived a whirlwind of aggression from the ferocious Belgian but her greater style and accuracy saw her win all three of the judges' scorecards and remain the undisputed women's lightweight world champion.
The pair had famously fought in Madison Square Garden in New York in a fight which was instantly dubbed a classic, with Persoon heavily protesting the verdict.
However, this time she had no complaints.
"This time I respect the result. The weight was too much. I ate, ate, ate but didn't have the power to hurt her," the Belgian said in her post-match interview.
Taylor began the fight well, her movement and footwork seeing her outclass Persoon in the early rounds. The latter tore forward with abandon but walked into a few big hits while flailing, largely ineffectually, at Taylor.
The Belgian had swelling under her eye and her face was already looking bloodied as they retreated to their corners after Round 2.
The word before the fight was that it was imperative that Taylor not get dragged into a dogfight, a view that the champion wasn't shy about expressing herself.
However, she endured something of an ordeal midway through the bout as Persoon's all-action intensity began to overwhelm Taylor in spots.
Taylor was however anxious not to get sucked into a brawl as she had in New York and though the Belgian's manic intensity caused problems, the defending champion kept her cool.
Persoon refused to take a backward step and she landed a high volume of shots, with her right hand proving highly effective.
Taylor responded with a burst of punches on the bell as Persoon tumbled to the floor almost in exhaustion.
Person, who said after the fight she might have broken her nose in the second round, was gracious in defeat and felt Taylor had done enough to retain her WBC, IBF, WBO and WBA titles.
The judges were unanimous in their agreement that Taylor won the fight, scoring it 98-93, 96-94, 96-94 in favour of the Irish fighter.
"It's never going to be an easy fight against Delfine," Taylor said afterwards.
"I knew I had to dig deep at some stages during the fight.
"I thought I boxed a lot better than the last time. I stuck to my boxing a bit more even though I got dragged in a few times but for the most part I stuck to my boxing and that's what got me the win in the end."
