Real World Background
The Battle of Bannockburn was a real battle, fought on June 24, 1314. The day before the battle, while the armies were still moving into place, Robert the Bruce defeated and slew the English knight Sir Henry de Bohun in single combat. The Scots won the battle thanks partly to a set of ingenious pit-traps that the English knights stumbled into, partly because the Scottish camp-followers decided to join in the fighting and the English mistook them for fresh reinforcements and fled.
