The Duke of Brabant arrived late to the Battle of Agincourt, and in his eagerness to reach the field, he dressed in improvised armour and wore a surcoat made from a trumpeter's flag. He fought valiantly but was captured. He was killed at the massacre of the prisoners ordered by Henry V of England, the English being unaware of his high status and ransom value.
The massacre was carried out as the smaller English force found itself stretched to its limits, guarding prisoners with the battle still not won. A counterattack (or false alarm) is thought to have driven King Henry to the decision, and some chroniclers have given Brabant's belated charge as this very cause, adding to the Duke's chivalric but tragic final story (see "Agincourt", J. Barker 2005).
