Modern historians tend to side with Henry in this affair, suggesting he had every reason to believe Alfonso was planning to invade. The king of Castile did in fact impose his terms on Henry, who in addition to providing a royal marriage, promised to join him in a war against the Moors. As with his crusading vow, Henry had no intention of fighting infidels anywhere. He was more concerned with installing Edward peacefully in Gascony before proceeding, with his wife and entourage, to Chartres for his first meeting ever with Louis, who was finally back from his miserable experience overseas. The occasion would be renowned for one of the most unique family reunions in history. Queen Eleanor, her sister Margaret, the queen of France, and their sister Sanchia, Richard’s wife, were joined by their youngest sister, Beatrice, who was the wife of Louis’ brother Charles of Anjou. Four sisters had married two sets of brothers, leading Louis to remark, perhaps innocently enough, that the children of each family would be more like brothers and sisters than cousins.
