The receiver of Fulk’s famous letter had gone before him to the grave; Louis From-over-sea, the grandson of Eadward the Elder, the last Karolingian worthy of his race, had died in 954. His death brought the house of France a step nearer to the throne; but it was still only one step. Lothar, the son of Louis, was crowned in his father’s stead; two years later the king-maker followed the king; and thenceforth his son, the new duke of the French, Hugh Capet, steadily prepared to exchange his ducal cap for a crown which nevertheless he was too prudent to seize before the time. In the face of countless difficulties, Louis in his eighteen years’ reign had contrived to restore the monarchy of Laon to a very real kingship. His greatest support in this task had been his wife’s brother, the Emperor Otto the Great. The two brothers-in-law, who had come to their thrones in the same year, were fast friends in life and death; and Otto remained the faithful guardian of his widowed sister and her son. So long as he lived, Hugh’s best policy was peace; and while Hugh remained quiet, there was little scope for military or political action on the part of his adherent Geoffrey of Anjou. In 973, however, the great Emperor died; and soon after he was gone the alliance between the Eastern and Western Franks began to shew signs of breaking. Lothar and Otto II. were brothers-in-law as well as cousins, but they were not friends as their fathers had been. In an evil hour Lothar was seized with a wild longing to regain the land which bore his name,--that fragment of the old “Middle Kingdom,” known as the duchy of Lotharingia or Lorraine, which after long fluctuating between its attachment to the imperial crown and its loyalty to the Karolingian house had finally cast in its lot with the Empire, with the full assent of Louis From-over-sea. Lothar brooded over its loss till in 978, when Otto and his queen were holding their court at Aachen, his jealousy could no longer endure the sight of his rival so near the border, and he summoned the nobles of his realm to an expedition into Lorraine.[268] Nothing could better fall in with the plans of Hugh Capet than a breach between Lothar and Otto; the call to arms was readily answered by the duke and his followers, and the grey tunic of the Angevin count was conspicuous at the muster.[269] The suddenness of Lothar’s march compelled Otto to make a hasty retreat from Aachen; but all that the West-Franks gained was a mass of plunder, and the vain glory of turning the great bronze eagle on the palace of Charles the Great towards the east instead of the west.[270] While they were plundering Aachen Otto was preparing a counter-invasion.[271] Bursting upon the western realm, he drove the king to cross the Seine and seek help of the duke, and before Hugh could gather troops enough to stop him he had made his way to the gates of Paris. For a while the French and the Germans lay encamped on opposite banks of the river, the duke
