This was the first world heavyweight title bout ever held in Germany.
Mildenberger was the first southpaw to fight for the World Heavyweight Title.
Ali was a 10-1 favorite.
There was a crowd of about 40,000.
Introduced in the ring prior to the bout were former World Heavyweight Champions Max Schmeling, Joe Louis, and Ingemar Johansson.
Ali and Mildenberger wore six-ounce British gloves.
Mildenberger’s left eye was badly cut in the sixth round and almost completely closed by the eighth round.
Mildenberger was knocked down in rounds five, eight, and ten.
Referee Teddy Waltham of Great Britain stopped the bout at 1:28 of the 12th round to protect Mildenberger from further punishment.
The fight was scored by rounds. At the time of the stoppage, Referee Teddy Waltham had Ali ahead 7-2-2, and Judges Felix Ohlet and Nat Fleischer (editor of The Ring magazine) each had Ali leading 7-3-1. The Associated Press had Ali in front 9-1-1.
One of the promoters said Ali would collect a purse of about $300,000 and Mildenberger about $100,000 of the total gross of approximately $750,000 from the gate receipts and television.
Questioned in 1973, Ali said that Mildenberger, not Joe Frazier, was his most difficult opponent to date.
