But while the negotiation was pending, other armaments arrived, and even the king began to perceive that to purchase the retreat of one while so many others were left to pursue their depredations, was great folly. The negotiation, consequently, assumed a new character: and the pirates were now to be paid, not for leaving the kingdom, but for assisting to expel other bodies of their countrymen from it. Accordingly, there followed some desultory hostilities between these kindred robbers: but while they were thus occupied, other bands were carrying their depredations into the heart of France. In the end, however, two of the armaments were persuaded to leave the shores—probably to join in the conquest of England, now governed by the feeble brothers of Alfred. But two yet remained that of Hastings, and one stationed in the Loire. As the former was so dreaded, his neutrality, at least, was to be purchased on any terms. The abbot of St. Denis repaired to the head quarters of the chief, and with some difficulty prevailed on him to accept the royal offers. These were, a large sum of money, and the fief of Chartres with the title of count, on the condition of his embracing Christianity, and, as a French vassal, of aiding his liege superior against all enemies. The conditions were accepted, and the fierce pirate of the Baltic became one of the noblest peers of France.[285] [Sidenote: 863 to 876.] There now remained one piratical band only,—that on the Loire. As Paris had been more than once menaced, king Charles caused to be constructed on the Seine, below that city, a bridge, which was intended to arrest the progress of the hostile vessels, by its inability to admit the high masts. The writers of that period are minute in describing the excesses of these men, whom they accompany step by step. But the detail is tedious: in general they have more sympathy for churches and abbeys, than for the peasantry; and much louder is their cry when a solitary priest is massacred at the altar, or a sacred relic borne away, than when a town is put to the sword. No church, no monastery, no village or town was spared,—nothing which had not the means of self-defence. In 867 the robbers appeared in the vicinity of Paris: the bridge prevented their arriving under the walls; and they established their head quarters at the abbey of St. Denis. From thence they spread into the neighbouring country, and acquired immense booty. But a contagious disease appearing among them, and reducing their numbers, they slowly descended the river to wait for reinforcements, which were constantly arriving on the coast. But these reinforcements were now smaller than they had lately been: three fourths of all the pirates that swept the seas were in England, preparing to drive Alfred from the throne; and though those who remained in France effected great mischief, they would have been unable to resist any considerable body. They were not, however, inured to open campaigns:
