1405 was the "Year of the French" in Wales. A formal treaty between Wales and France was negotiated. On the continent the French pressed the English as the French army invaded English Plantagenet Aquitaine. Simultaneously, the French landed in force at Milford Haven in west Wales. They marched through Herefordshire and on into Worcestershire. They met the English army just ten miles from Worcester. The armies took up battle positions daily and viewed each other from a mile without any major action for eight days. Then, for reasons that have never become clear, the Welsh retreated, and so did the French shortly afterwards.
