Personal conflict between Bruce and Sir Henry de Boune
By this time the King of England had brought up his main army, and ordered a halt, for the purpose of consulting with his leaders, whether it were expedient to join battle that same day, or take a night to refresh his troops. By some mistake, however, the centre of the English continued its march, not aware of this order, and on their approach to the New Park, Bruce rode forward alone to make some new arrangements, which were called for by the absence of Randolph, and to take a final view of the disposition of his army. He was at this time in front of his own line, meanly mounted on a hackney, but clad in full armour, with his battle-axe in his hand, and distinguished from his nobles by a small crown of gold surmounting his steel helmet.
On the approach of the English vaward, led by the Earls of Gloucester and Hereford, Sir Henry de Boune, an English knight, who rode about a bowshot in advance of his companions, recognised the king, and galloped forward to attack him. Boune was armed at all points, and excellently mounted on a heavy war-horse, so that the contest was most unequal, and Bruce might have retired; but for a moment he forgot his duties as a general in his feelings as a knight, and, to the surprise of his soldiers, spurred his little hackney forward to his assailant. There was an interval of breathless suspense, but it lasted only a moment; for as the English knight came on in full career, the king parried the spear, and raising himself in his stirrups as he passed, with one blow of his battleaxe laid him dead at his feet, by almost cleaving his head in two.
