On 26 July 1513 James IV responded to pleas for assistance from France and declared war on England.
Aside from assisting the French, who had been invaded by an English army, James was also aggrieved at England's seizing of two Scottish ships and the non-payment of part of the dowry for his wife, Margaret Tudor. The war did not go to plan, however, and the Scots suffered probably their greatest military defeat at Flodden in September where James was killed.
