As for what Rolf actually did for Rouen, that remains to be seen rather from the after state of affairs. "The founder of the Rouen colony," Freeman says, "is a great man who must be content to be judged in the main by the results of his actions." Rolf is not in the least a vague or shadowy personality, but it is noticeable how he has grown to us out of a great tangle of myths and very little fact. All we have to go upon is the not very authentic Roman de Rou, a few Norse legends, and sundry brief allusions by later French writers, who class him, together with all the Rouennais, under the contemptuous term Pirate. It was a well-ordered, strong, self-dependent colony that he handed down to the long line of his successors. These carried on bravely the traditions of their founder and brought up a hardy race of fighters, although Rouen itself was never thoroughly Teutonic, never at least since the very early days of Rolf's colony. The religion, the language, and many of the customs of the French at Lâon were grafted on to the Northmen of Rouen by their leader, and thus the town stood as much apart from the rest of Neustria as from the Franks themselves. After the death of Rolf and of his successor, William Longsword, Louis from beyond Sea, of the race of Charlemagne, ruled at Lâon, and cast envious eyes on Normandy, even occupying Rouen for some time during the minority of Richard the Fearless. But although Rouen was ultimately to become a town of France, the time was not yet, and for the present her destiny was averted by an outsider--Harold, King of Denmark, curiously surnamed Blue-tooth. He determined to resist the encroachments of Louis, and finally made him prisoner in the city where he had hoped to establish another capital.
The Norman dukes only deteriorated as rulers when they joined to their domain the crown of England, won by the hardiest and strongest of them all. We remember the passionate, self-willed Robert, son of the Conqueror, and John, called Lackland, that disgrace to the English throne, the worst and likewise the last Norman duke, for the French king, Philippe Auguste, confiscated Normandy, together with other English possessions, and joined it to the crown of France, taking possession of Rouen after a siege in 1204. From this point the history of Rouen becomes the history of a French and not of a Norman town. As a reward for its submission, Philippe Auguste presented the town with a castle, of which one tower (the Tour Jeanne d'Arc) alone remains standing. Two centuries later, Rouen was in danger from the English. Henry V., during his brilliant campaign in northern France, was not likely to leave to itself such an important place. In 1419 he set up his cannon outside the walls, and proceeded to blockade the town, which opened its gates to him after a six months' siege. Here he also built a castle, which, in the hopefulness born of youth and victory, he intended to use as a royal residence when all France should be at rest under his firm rule. But before the conquest was completed, before he had time to think about any residence other than his camp, came that last fatal sickness at Vincennes, and the castle, which seemed, like all his victories, so sure and so lasting, has been swept off the face of the earth. The years after Henry's death, however, were significant ones for Rouen, now in English hands, and in 1431 we come to the great point in its history, the trial and burning of Joan of Arc in the market-place.
