It was almost certainty a calculated insult to Louis VII that Margret of France was not crowned alongside her husband in 1170. Robert of Torigny claims she simply arrived from Normandy too late to participate, but other sources reveal she was deliberately delayed at Caen. Warren believes that this was an ultimately fruitful attempt to prevent Louis VII from dissuading Thomas Becket from accepting his latest overtures. Whatever the case, Louis was so enraged by this that he launched an immediate attack on the Norman border, forcing Henry to return to the duchy personally to oversee its defences. Mediation by Count Theobald of Blois, however, lead to a meeting between the two monarchs at Vendôme and, following subsequent meetings at La Ferté and Fréteval Henry was able to placate King Louis.
