In the course of the war with Normandy, when Harald Bluetooth’s Norwegians were ravaging France, and were encamped before the walls of Paris, a gigantic Berserk daily advanced to the gate of the city, challenging the French knights to single combat. Several who accepted it fell by his hand; and King Lothaire forbade any further attempts to attack him. Count Geoffrey was at this time collecting his vassals to come to the King’s assistance; and no sooner did he hear of the defiance of the Northman, than, carried away by the spirit of knight-errantry, he bade his forces wait for him at Chateau Landon; and, without divulging his purpose, rode off, with only three attendants, to seek the encounter. He came to the bank of the Seine in early morning, caused a miller to ferry him and his horse across the river, leaving his squires on the other side, and reached the open space before the walls in time to hear and answer the Northman’s daily challenge. The duel ended in the death of the giant, and was witnessed by the French on the walls; but they did not recognize their champion, and before they could come down to open the gates, and thank him, he was gone. He had cut off the enemy’s head, and, bidding the miller carry it to the King, crossed the Seine again, met his squires at the mill, and rejoined his vassals at Landon, without letting any one know what had happened.
Lothaire was very anxious to know who the champion was; but all the miller could tell him was, that it had been a man of short stature, and slight, active figure, a capital horseman, whom he was sure he should know again anywhere. In due time the nobles collected with their troops, and Geoffrey among them. When they were in full assembly, Lothaire introduced the miller, bidding him say whether the knight-errant was present. The man fixed his eyes on the Count of Anjou, who wore a cassock of coarse gray wool over his armor. “Yes,” he said, “‘tis he--_à la grise gonnelle_.”
It is also said that Geoffrey took his name from his frequent pilgrimages to Rome, in which he wore the gray “palmer’s amice.” He was a favorable specimen of the Angevin character, the knight-errant element predominating over its other points, and rendering him honorable and devout, and not more turbulent than could be helped by a feudal chief of the tenth century. He died near Saumur, while besieging the castle of a refractory vassal, in the year 987.
