On hearing of the fall of Lanark, and on the receipt of the proclamation calling upon all true Scotchmen to join him in his effort to deliver their country from its yoke, the people began to flock in in great numbers.

Richard Wallace of Riccarton and Robert Boyd came in with such force as they could collect from Kyle and Cunningham, among whom were not less than 1000 horsemen.

Sir John Grahame, Sir John of Tinto, and Auchinleck assembled about 3000 mounted troops and a large number of foot, many of whom, however, were imperfectly armed.

Sir Ronald Crawford, Wallace's uncle, being so close to Ayr, could not openly join him, but secretly sent reinforcements and money.

Many other gentlemen joined with their followers.
The news of the fall of Lanark and of the numbers who were flocking to join Wallace paralysed the commanders of the English garrisons, and for a time no steps were taken against him; but news of the rising was instantly sent to King Edward, who, furious at this fresh trouble in Scotland, which he had deemed finally conquered, instantly commenced preparations for another invasion.
