Beynon was a collier from the South Wales coalfield who supplemented his wages by taking up boxing while still a teenager.
Stanley was the reigning British and Empire bantamweight champion and was favourite to win the bout and retain his belt.
Beynon's term as the bantam weight title holder was short lived, as after a win over Frenchman Robert Dastillon, he failed in his first defence of the belt, against Digger Stanley; losing in the same way as he won, by points over 20 rounds.
When Beynon first faced Ledoux, it was for the European bantamweight championship title, and he lost the fight after being forced to retire in the eighth round after his eyebrow was split.
The second challenge against Ledoux was far more clear cut, with the Frenchman outboxing Beynon at close-quarters, and won the contest by knockout in the eighth.
