soldiers from crossing together (possibly as few as three men abreast), so, while the English soldiers crossed, the Scots held back until half of them had passed and then killed the English as quickly as they could cross. The infantry were sent on first, followed by heavy cavalry. The Scots' schiltron formations forced the infantry back into the advancing cavalry. A pivotal charge, led by one of Wallace's captains, caused some of the English soldiers to retreat as others pushed forward, and under the overwhelming weight, the bridge collapsed and many English soldiers drowned. Thus, the Scots won a significant victory, boosting the confidence of their army. Hugh de Cressingham, Edward's treasurer in Scotland, died in the fighting and it is reputed that his body was subsequently flayed and the skin cut into small pieces as tokens of the victory. The Lanercost Chronicle records that Wallace had "a broad strip [of Cressingham's skin] ... taken from the head to the heel, to make therewith a baldrick for his sword". After the battle, Moray and Wallace assumed the title of Guardians of the Kingdom of Scotland on behalf of King John Balliol. Moray died of wounds suffered on the battlefield sometime in late 1297. Around November 1297, Wallace led a large-scale raid into northern England, through Northumberland and Cumberland. In a ceremony, at the 'Kirk o' the Forest' (Selkirk), towards the end of the year, Wallace was knighted. This would have been carried out by one of three Scottish earls—Carrick, Strathearn or Lennox. Battle of Falkirk In April 1298, Edward ordered a second invasion of Scotland. Two days prior to the battle 25,781 foot soldiers were paid. More than half of them would have been Welsh. There are no clear cut sources for the presence of cavalry, but it is safe to assume that Edward had roughly 1,500 horse under his command. They plundered Lothian and regained some castles, but failed to bring William Wallace to combat; the Scots shadowed the English army, intending to avoid battle until shortages of supplies and money forced Edward to withdraw, at which point the Scots would harass his retreat. The English quartermasters' failure to prepare for the expedition left morale and food supplies low, and a resulting riot within Edward's own army had to be put down by his cavalry. In July, while planning a return to Edinburgh for supplies, Edward received intelligence that
