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 1500 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 the Scots were encamped nearby at Falkirk, and he moved quickly to engage them in the pitched battle he had long hoped for.
