The state of affairs in 1589 was that Henry of Navarre, now Henry IV of France, held the south and west, and the Catholic League the north and east. The leadership of the Catholic League had devolved to the Duke de Mayenne, who was appointed Lieutenant-General of the kingdom. He and his troops controlled most of rural Normandy. However, in September 1589, Henry inflicted a severe defeat on the Duke at the Battle of Arques. Henry's army swept through Normandy, taking town after town throughout the winter.
