A tough old knight in his late fifties, Tweng was a Yorkshire veteran of the wars against the Scots, despite being distantly related to Bruce. He showed great courage when the English were defeated at Stirling Bridge in 1297, forcing his way through the Scottish ranks to safety.
He knew the area around Stirling well, having been commander of the castle for two years.
It is his actions at the end of the battle which have added to Marmaduke Tweng’s colourful story. He is said to have hidden his distinctive parrot-emblazoned armour in a bush after the battle to avoid being recognised and captured, and then handed himself over to Robert Bruce himself. He greeted the Scots leader, went down on one knee, and gave himself up.
Tweng survived Bannockburn. Bruce showed respect for his experienced opponent by entertaining him and treating him courteously, before sending him home to Yorkshire, armour intact and without having to pay a ransom.
