Let us leave Louis the Debonnair his traditional name, although it is not an exact rendering of that which was given him by his contemporaries. They called him Louis the Pious. And so indeed he was, sincerely and even scrupulously pious; but he was still more weak than pious, as weak in heart and character as in mind, as destitute of ruling ideas as of strength of will; fluctuating at the mercy of transitory impressions, or surrounding influences, or positional embarrassments. The name of Debonnair is suited to him; it expresses his moral worth and his political incapacity, both at once.
As king of Aquitania, in the time of Charlemagne, Louis made himself esteemed and loved; his justice, his suavity, his probity, and his piety were pleasing to the people, and his weaknesses disappeared under the strong hand of his father. When he became emperor, he began his reign by a reaction against the excesses, real or supposed, of the preceding reign. Charlemagne’s morals were far from regular, and he troubled himself but little about the license prevailing in his family or his palace. At a distance he ruled with a tight and a heavy hand. Louis established at his court, for his sisters as well as his servants, austere regulations. He restored to the subjugated Saxons certain of the rights of which Charlemagne had deprived them. He sent out everywhere his commissioners (missi dominici) with orders to listen to complaints and redress grievances, and to mitigate his father’s rule, which was rigorous in its application, and yet insufficient to repress disturbance, notwithstanding its preventive purpose and its watchful supervision.
Almost simultaneously with his accession, Louis committed an act more serious and compromising. He had, by his wife Hermengarde, three sons, Lothaire, Pepin, and Louis, aged respectively nineteen, eleven, and eight. In 817 Louis summoned at Aix-la-Chapelle the general assembly of his dominions; and there, whilst declaring that “neither to those who were wisely-minded, nor to himself, did it appear expedient to break up, for the love he bare his sons and by the will of man, the unity of the empire, preserved by God himself,” he had resolved to share with his eldest son, Lothaire, the imperial throne. Lothaire was in fact crowned emperor; and his two brothers, Pepin and Louis, were crowned king, “in order that they might reign, after their father’s death and under their brother and lord, Lothaire, to wit: Pepin, over Aquitaine and a great part of Southern Gaul and of Burgundy; Louis, beyond the Rhine, over Bavaria and the divers peoplets in the east of Germany.” The rest of Gaul and of Germany, as well as the kingdom of Italy, was to belong to Lothaire, emperor and head of the Frankish monarchy, to whom his brothers would have to repair year by year to come to an understanding with him and receive his instructions. The last-named kingdom, the most considerable of the three, remained under the direct government of Louis the Debonnair, and at the same time of his son Lothaire, sharing the title of emperor. The two other sons, Pepin and Louis, entered, notwithstanding their childhood, upon immediate possession, the one of Aquitaine and the other of Bavaria, under the superior authority of their father and their brother, the joint emperors.
Charlemagne had vigorously maintained the unity of the empire, for all that he had delegated to two of his sons, Pepin and Louis, the government of Italy and Aquitaine, with the title of king. Louis the Debonnair, whilst regulating beforehand the division of his dominion, likewise desired, as he said, to maintain the unity of the empire. But he forgot that he was no Charlemagne.
It was not long before numerous mournful experiences showed to what extent the unity of the empire required personal superiority in the emperor, and how rapid would be the decay of the fabric when there remained nothing but the title of the founder.
In 816 Pope Stephen IV. came to France to consecrate Louis the Debonnair emperor. Many a time already the Popes had rendered the Frankish kings this service and honor. The Franks had been proud to see their king, Charlemagne, protecting Adrian I. against the Lombards; then crowned emperor at Rome by Leo III., and then having his two sons, Pepin and Louis, crowned at Rome, by the same Pope, kings respectively of Italy and of Aquitaine. On these different occasions, Charlemagne, whilst testifying the most profound respect for the Pope, had, in his relations with him, always taken care to preserve, together with his political greatness, all his personal dignity. But when, in 816, the Franks saw Louis the Pious not only go out of Rheims to meet Stephen IV., but prostrate himself, from head to foot, and rise only when the Pope held out a hand to him, the spectators felt saddened and humiliated at the sight of their emperor in the posture of a penitent monk.
Several insurrections burst out in the empire; the first amongst the Basques of Aquitaine; the next in Italy, where Bernard, son of Pepin, having, after his father’s death, become king in 812, with the consent of his grandfather Charlemagne, could not quietly see his kingdom pass into the hands of his cousin Lothaire at the orders of his uncle Louis. These two attempts were easily repressed, but the third was more serious. It took place in Brittany, amongst those populations of Armorica who were still buried in their woods, and were excessively jealous of their independence. In 818 they took for king one of their principal chieftains, named Morvan; and, not confining themselves to a refusal of all tribute to the king of the Franks, they renewed their ravages upon the Frankish territories bordering on their frontier. Louis was at that time holding a general assembly of his dominions at Aix-la-Chapelle; and Count Lantbert, commandant of the marches of Brittany, came and reported to him what was going on. A Frankish monk, named Ditcar, happened to be at the assembly: he was a man of piety and sense, a friend of peace, and, moreover, with some knowledge of the Breton king Morvan, as his monastery had property in the neighborhood. Him the emperor commissioned to convey to the king his grievances and his demands. After some days’ journey the monk passed the frontier, and arrived at a vast space enclosed on one side by a noble river, and on all the others by forests and swamps, hedges and ditches. In the middle of this space was a large dwelling, which was Morvan’s. Ditcar found it full of warriors, the king having, no doubt, some expedition on hand. The monk announced himself as a messenger from the emperor of the Franks. The style of announcement caused some confusion, at first, to the Briton, who, however, hasted to conceal his emotion under an air of good-will and joyousness, to impose upon his comrades. The latter were got rid of; and the king remained alone with the monk, who explained the object of his mission. He descanted upon the power of the Emperor Lotus, recounted his complaints, and warned the Briton, kindly and in a private capacity, of the danger of his situation, a danger so much the greater in that he and his people would meet with the less consideration, seeing that they kept up the religion of their Pagan forefathers. Morvan gave attentive ear to this sermon, with his eyes fixed on the ground, and his foot tapping it from time to time. Ditcar thought he had succeeded; but an incident supervened. It was the hour when Morvan’s wife was accustomed to come and look for him ere they retired to the nuptial couch. She appeared, eager to know who the stranger was, what he had come for, what he had said, what answer he had received. She preluded her questions with oglings and caresses; she kissed the knees, the hands, the beard, and the face of the king, testifying her desire to be alone with him. “O king and glory of the mighty Britons, dear spouse of mine, what tidings bringeth this stranger? Is it peace, or is it war?” “This stranger,” answered Morvan with a smile, “is an envoy of the Franks; but bring he peace or bring he war, is the affair of men alone; as for thee, content thee with thy woman’s duties.” Thereupon Ditcar, perceiving that he was countered, said to Morvan, “Sir king, ‘tis time that I return; tell me what answer I am to take back to my sovereign.” “Leave me this night to take thought thereon,” replied the Breton chief, with a wavering air. When the morning came, Ditcar presented himself once more to Morvan, whom he found up, but still half-drunk, and full of very different sentiments from those of the night before. It required some effort, stupefied and tottering as he was with the effects of wine and the pleasures of the night, to say to Ditcar, “Go back to thy king, and tell him from me that my land was never his, and that I owe him nought of tribute or submission. Let him reign over the Franks; as for me, I reign over the Britons. If he will bring war on me, he will find me ready to pay him back.”
The monk returned to Louis the Debonnair, and rendered account of his mission. War was resolved upon; and the emperor collected his troops, Allemannians, Saxons, Thuringians, Burgundians, and Aquitanians, without counting Franks or Gallo-Romans. They began their march, moving upon Vannes; Louis was at their head, and the empress accompanied him, but he left her, already ill and fatigued, at Angers. The Franks entered the country of the Britons, searched the woods and morasses, found no armed men in the open country, but encountered them in scattered and scanty companies, at the entrance of all the defiles, on the heights commanding pathways, and wherever men could hide themselves and await the moment for appearing unexpectedly. The Franks heard them, from amidst the heather and the brushwood, uttering shrill cries, to give warning one to another, or to alarm the enemy. The Franks advanced cautiously, and at last arrived at the entrance of the thick wood which surrounded Morvan’s abode. He had not yet set out with the pick of the warriors he had about him; but, at the approach of the Franks, he summoned his wife and his domestics, and said to them, “Defend ye well this house and these woods; as for me, I am going to march forward to collect my people; after which to return, but not without booty and spoils.” He put on his armor, took a javelin in each hand, and mounted his horse. “Thou seest,” said he to his wife, “these javelins I brandish: I will bring them back to thee this very day dyed with the blood of Franks. Farewell.” Setting out he pierced, followed by his men, through the thickness of the forest, and advanced to meet the Franks.
The battle began. The large numbers of the Franks, who covered the ground for some distance, dismayed the Britons, and many of them fled, seeking where they might hide themselves. Morvan, beside himself with rage, and at the head of his most devoted followers, rushed down upon the Franks as if to demolish them at a single stroke; and many fell beneath his blows. He singled out a warrior of inferior grade, towards whom he made at a gallop, and, insulting him by word of mouth, after the ancient fashion of the Celtic warriors, cried, “Frank, I am going to give thee my first present, a present which I have been keeping for thee a long while, and which I hope thou wilt bear in mind;” and launched at him a javelin, which the other received on his shield. “Proud Briton,” replied the Frank, “I have received thy present, and I am going to give thee mine.” He dug both spurs into his horse’s sides, and galloped down upon Morvan, who, clad though he was in a coat of mail, fell pierced by the thrust of a lance. The Frank had but time to dismount and cut off his head, when he fell himself, mortally wounded by one of Morvan’s young warriors, but not without having, in his turn, dealt the other his death-blow.
It spreads on all sides that Morvan is dead; and the Franks come thronging to the scene of the encounter. There is picked up and passed from hand to hand a head all bloody and fearfully disfigured. Ditcar the monk is called to see it, and to say whether it is that of Morvan; but he has to wash the mass of disfigurement, and to partially adjust the hair, before he can pronounce that it is really Morvan’s. There is then no more doubt; resistance is now impossible; the widow, the family, and the servants of Morvan arrive, are brought before Louis the Debonnair, accept all the conditions imposed upon them, and the Franks withdraw with the boast that Brittany is henceforth their tributary.
