Medieval Combat Reenactment.
Quote: Some reenactment battles take the form of a competition, where the two "armies" try to defeat each other within the actions permitted by the combat rules.
The scenario here doesn't provide the exact Combat Rules, besides that it's Medieval period and the contestants will have to use gear from that period. It also doesn't provide a specific historical engagement to reference. It's more of a who would generally be better at this, I suppose.
