In 1116 Louis IV raided into Normandy again. Louis had supported Henry I's nephew, William Clito as the Duke of Normandy. By 1117 King Louis IV of France, Count Baldwin VII of Flanders and Fulk V of Anjou were all supporting William Clito against Henry I of England. The next summer Henry I returned to Normandy and the war began. Fulk V defeated Henry I at La Motte-Gautier on the border of Maine. In October of 1118 Fulk V again defeated Henry I at Alençon. Finally, after a series of defeats Henry I made peace with Fulk V. They sealed their truce by allowing the marriage of Fulk's daughter Matilda with Henry's son William William Adelin. Fulk V gave Maine as a dowry for his daughter Matilda. In 1120 Fulk V then made a pilgrimage to the Holy Land. He spent a year at Jerusalem. According to Orderic Vitalis he joined the Knights Templar. When he returned to Anjou Fulk left 100 knights behind for a year to help defend the Kingdom. He continued to pay the Templars a substantial yearly donation for the rest of his life.
