February 1303 witnessed the battle of Roslin, in which the Scots under John Comyn of Badenoch and Simon Fraser defeated an English force led by John Segrave.
In the pantheon of Scottish victories, Roslin seems to rank well below the likes of Stirling Bridge and Bannockburn. This is, perhaps, due to Comyn being generally perceived as a traitor who richly deserved a dagger in the guts, delivered by Robert de Bruce at Dumfries church in 1306. I have argued before that Comyn is much maligned, a victim of Bruce propaganda, but to little avail. Some impressions just stick and there is little point wasting energy on such things. Not my problem, squire.
Edward I had placed Segrave in command of an expeditionary force, ordered to reconnoitre Scotland before the main English invasion in the autumn. The size of his force reached a peak of 119 men-at-arms and 2067 footsoldiers by January 1303, probably reduced by the time of the battle in February. Segrave was dispatched, specifically, to repel the Scots threatening the English garrison at Roxburgh.
According to Walter of Guisborough, Segrave divided his men into three divisions or troops, distanced from each by about two leagues. He was then led into an ambush by a certain 'boy', who was really on Comyn's side. A notable feature of these Scottish wars is the frequent use of women and boys as spies. I like to think it was the same boy throughout, cheerfully playing off both sides and making a hatful of cash into the bargain.
On 24 February the first English troop, about three hundred men under Segrave's personal command, was attacked and scattered. The recorded casualties are light (just five horses), but Segrave himself was captured. Guisborough claims the second troop came up and rescued him, but this cannot be correct: a couple of weeks later, Edward I paid a ransom for Segrave, implying he was in Scottish custody.
One of the English casualties was Ralph Manton, the king's treasurer, also called Ralf the Cofferer. He was taken prisoner by Simon Fraser, who accused him of embezzling funds when Fraser had been in Edward I's service. After this angry speech - slightly embarrassing, in context - Fraser ordered one of his servants to cut off Ralf's hands and leave him to bleed to death in the forest.
Roslin was later blown out of proportion by the 15th century Scottish chronicler, Walter Bower, who claimed the English lost upward of 80,000 men. This sort of wild boasting and exaggeration was common: for instance, the English claimed that Wallace lost a hundred thousand men at Falkirk. Such losses would have wiped out the entire adult male population of the British Isles, never mind Scotland.
Nevertheless, Roslin was a significant morale-boosting victory for the Scots at a bleak time. It made no real difference to Edward's plans (although one imagines the royal eyes rolling a little at the news). The battle may, however, have persuaded him that Comyn and his allies were still capable of serious resistance. The terms of the negotiated settlement of Strathord, almost a year later, would imply as much.
