The English army withdrew from the Loire Valley and headed north on 18 June, joining with an expected unit of reinforcements under the command of Sir John Fastolf. Joan urged the Armagnacs to pursue, and the two armies clashed southwest of the village of Patay. The battle at Patay might be compared to Agincourt in reverse. The French vanguard attacked a unit of English archers who had been placed to block the road. A rout ensued that decimated the main body of the English army and killed or captured most of its commanders. Fastolf escaped with a small band of soldiers and became the scapegoat for the humiliating English defeat. The French suffered minimal losses.
