As a child, he had dreamed of playing the All Blacks but never beating them.
"This is quite amazing, because it does not happen often and has not happened for a long time. What is certain is that we continue to write our history and we have just passed an important mark against a very big team…This will remain etched in our memories," he said.
While they started at pace, Dupont said they knew it would be difficult to maintain that speed of game for 80 minutes and that the All Blacks would come back.
The Test against the All Blacks had been on the players' minds throughout the autumn series. That made it difficult to focus on the earlier games, he said.
But he also said they could not get carried away with the win. Much hard work remained.
"Two years is a very long time in sports. If you look at where the Springboks were two years before their World Cup win in 2019, I'm not sure we would have bet a Euro on them. Let's say that we are on our way, that we are in a good position and are evolving well.
"But we know for a fact the French XV will be expected to perform like that every time. The goal has to be to maintain this kind of performance in each of our games.
"The next appointment is the Six Nations. That will show us even more about where we are in our evolution," he said.
