In a breathing-space which followed upon this last attack, Charles received from Æthelwulf of Wessex a personal visit and an overture of mutual alliance against the common foe. The scheme was shattered by a political revolution in Wessex which followed Æthelwulf’s return; and meanwhile a new danger to the Karolingian power arose in the threatening attitude of Robert the Brave, a warrior of obscure birth who was now count of the Angevin march. Under pretext, as it seems, of securing their aid against the northmen, Robert leagued himself with the foes of the monarchy beyond his two frontier rivers, and made a triple alliance with the revolted Bretons and the king’s rebel nephew, Pepin of Aquitaine.[238] Charles, more and more hard pressed every year by domestic and political difficulties, and haunted by the perpetual horror of the pirate ships always in the background, felt that this second wavering lord of the marchland must be won back at any cost. Two years later, therefore, the count of the Angevin march was invested with a vast duchy comprising the whole territory between Seine and Loire as far as the sea and the Breton border; and with this grant the special work of keeping out both Bretons and northmen was distinctly laid upon his shoulders.[239]

Robert fulfilled his trust gallantly and successfully till he fell in a Scandinavian ambush at Brissarthe in 866.[240] His territories were given to a cousin of the king, Hugh of Burgundy, who was either so incapable or so careless of their defence that before six years had passed he suffered the very corner-stone of his duchy, the most important point in the whole scheme of operations against the northmen in central Gaul, to fall into the enemies’ hands. A band of pirates, sailing unopposed up the Loire and the Mayenne after Robert’s death, found Angers deserted and defenceless, and settling there with their families, used it as a centre from which they could securely harry all the country round. The bulk of the pirate forces, however, was now concentrated upon a great effort for the conquest of Britain, and while the invaders of Angers lay thus isolated from their brethren across the Channel, Charles the Bald seized his opportunity to attempt the recovery of the city. In concert with the Breton king, Solomon, he gathered his forces for a siege; the Franks encamped on the eastern side of the Mayenne, the Bretons on the opposite shore. Their joint blockade proved unavailing, till one of the Bretons conceived the bold idea of turning the course of the Mayenne, so as to leave the pirate ships stranded and useless. The whole Breton army at once set to work and dug such an enormous trench that the northmen saw their retreat would be hopelessly cut off. In dismay they offered to purchase, at a heavy price, a free withdrawal from Angers and its district; their offer was accepted, and Angers was evacuated accordingly.[241]

But the long keels sailed away only to return again. Amid the gathering troubles of the Karolingian house, as years passed on, the cry rose up ever louder and louder from the desolated banks of Seine, and at last even from the inland cities of Reims and Soissons, perilously near the royal abode at Laon itself: “From the fury of the northmen, good Lord, deliver us!” It was not from Laon that deliverance was to come. The success of Charles the Bald at Angers, the more brilliant victory of his grandson Louis III. over Guthrum at Saucourt, were but isolated triumphs which produced no lasting results. At the very moment when the Karolingian empire was reunited under the sceptre of Charles the Fat came the crisis of the struggle with the northmen in West-Frankland; and the true national leader shewed himself not in the heir of Charles the Great, but in Count Odo of Paris, the son of Robert the Brave. It was Odo who saved Paris from the northmen when they besieged it with all their forces throughout the winter of 885; and by saving Paris he saved the kingdom. Before the siege was raised the possessions which his father had held as duke of the French were restored to him by the death of Hugh of Burgundy. A few months later the common consent of all the Karolingian realms deposed their unworthy Emperor, and the acclamations of a grateful people raised their deliverer Odo to the West-Frankish throne.

The times, however, were not yet ripe for a change of dynasty, and the revolution was followed by a reaction which on Odo’s death in 898 again set a Karolingian, Charles the Simple, upon the throne; but though the monarchy of Laon lingered on till the race of Charles the Great became extinct, it was being gradually undermined and supplanted by the dukes of the French, the rulers of the great duchy between Seine and Loire. Paris was now, since the siege of 885, the chief seat of the ducal power; and in the new feudal organization which grew up around this centre, the cradle of the ducal house, the border-stronghold of Angers, sank to a secondary position. The fiefs which the dukes parcelled out among their followers fell to the share of men of the most diverse origin and condition. In some cases, as at Chartres and Tours, the Scandinavian settler was turned into a peaceful lieutenant of the Frankish chief against whom he had fought. In others the reward of valour was justly bestowed on men who had earned it by their prowess against the invaders. It may be that the old alliance of Count Robert the Brave with the Bretons had sowed the seeds of a mighty tree. In the depths of a gloomy forest-belt which ran along the Breton border at the foot of a range of hills that shelter the western side of the valley of the Mayenne, there dwelt in Robert’s day—so the story went—a valiant forester, Tortulf. He quitted the hardy, hazardous borderer’s life—half hunter, half bandit—to throw himself into the struggle of Charles the Bald and Robert the Brave against the northmen: Charles set him to keep the pirates out of Touraine, and gave him a congenial post as forester of a wooded district known as the “Nid-de-Merle”—the Blackbird’s Nest. In its wild fastnesses Tortulf lay in wait for the approach of the marauders, and sprang forth to meet them with a daring and a success which earned him his sovereign’s favour and the alliance of the duke of the French. His son, Ingelger, followed in his steps; marriage came to the help of arms, and with the hand of Ælendis, niece of the archbishop of Tours, Ingelger acquired her lands at Amboise. The dowry was a valuable one; Amboise stood in the midst of one of the most rich and fertile districts of central France, half way between Tours and Blois, on the south bank of the Loire, which was spanned at this point by a bridge said to have been built by Julius Cæsar; two centuries later tradition still pointed out the site of Cæsar’s palace on the banks of the little river Amasse, at the western end of the town; while opposite the bridge a rocky brow, crowned to-day by the shell of a magnificent castle of the Renascence, probably still kept in Ingelger’s days some traces of a fortress built there by a Roman governor in the reign of the Emperor Valens. A mightier stronghold than Amboise, however, was to be the home of Ingelger’s race. His son, a ruddy youth named Fulk, early entered the service of Count Odo of Paris and remained firmly attached to him and his house; and one of the earliest acts of Odo’s brother Robert, who succeeded him as duke of the French—if indeed it was not rather one of the last acts of King Odo himself—was to intrust the city of Angers to Fulk the Red as viscount.[242] The choice was a wise one; for Fulk was gifted with a sound political instinct which found and kept the clue to guide him through all the revolutions and counter-revolutions of the next forty years. He never swerved from his adherence to the dukes of the French; and by his quiet tenacity he, like them, laid the foundation of his house’s greatness. Preferments civil and ecclesiastical—the abbacies of S. Aubin and S. Licinius at Angers, the viscounty of Tours, though this was but a momentary honour—were all so many stepping-stones to his final investiture, shortly before the death of Charles the Simple, as count of the Angevin March.
