Hey, I remembered it right-ish after all:

Tennis star Jean Borotra offered to vault the wall and run through a gauntlet of enemy soldiers, which Lee accepted. Borotra managed to get through unscathed, requested a uniform, and then joined the relief force as it made its way towards the prison just before the defenders were out of ammo.

Also the story with a Sabaton song lol https://www.sabaton.net/historical-facts/the-battle-of-castle-itter/
