The Cambridge star ran a Paralympic record of 10.90 seconds to take the title of the fastest amputee in the world on Thursday, sending 80,000 inside the Olympic Stadium into raptures.
The 19-year-old led from the start and never looked like relinquishing his grip on gold in a stunning race which capped a brilliant night for British sport.
There were also track golds for Hannah Cockroft and David Weir – his third of the Games – with Peacock calling the British performance “crazy”.
Having taken Pistorius’ crown, Peacock’s superstardom is confirmed, but he admits he is still coming to terms with the magnitude of what he has achieved.
“I saw Hannah go out and get the first gold and that was great to see and I knew it was going to be a crazy night,” he said.
“We had 10 finalists last night alone so I think it was our biggest night in athletics. It was absolute crazy.
“The British crowd has made the Games come alive, they are absolutely amazing. They were chanting my name before the race started and that was unreal.
“When it [the result] came up on the board I just gave Oscar a big hug and he said to me ‘I told you you would do it’. I’ve got so much respect for him he is such a legend in Paralympic sport.
“I got three hours sleep afterwards and hopefully later I will have a bit of time to sit down and reflect on the race. I will go through how it went with my coach and have a sit down and a few beers.”
