On whichever side of the border chance had thrown Joanna, the same love to France would have been nurtured. For it is a strange fact, noticed by M. Michelet and others, that the Dukes of Bar and Lorraine had for generations pursued the policy of eternal warfare with France on their own account, yet also of eternal amity and league with France in case anybody else presumed to attack her. Let peace settle upon France, and before long you might rely upon seeing the little vixen Lorraine flying at the throat of France. Let France be assailed by a formidable enemy, and instantly you saw a Duke of Lorraine insisting on having his own throat cut in support of France; which favour accordingly was cheerfully granted to him in three great successive battles: twice by the English, viz., at Crécy and Agincourt, once by the Sultan at Nicopolis.
This sympathy with France during great eclipses, in those that during ordinary seasons were always teasing her with brawls and guerilla inroads, strengthened the natural piety to France of those that were confessedly the children of her own house. The outposts of France, as one may call the great frontier provinces, were of all localities the most devoted to the Fleurs de Lys. To witness, at any great crisis, the generous devotion to these lilies of the little fiery cousin that in gentler weather was for ever tilting at the breast of France, could not but fan the zeal of France's legitimate daughters; while to occupy a post of honour on the frontiers against an old hereditary enemy of France would naturally stimulate this zeal by a sentiment of martial pride, by a sense of danger always threatening, and of hatred always smouldering. That great four-headed road was a perpetual memento to patriotic ardour. To say "This way lies the road to Paris, and that other way to Aix-la-Chapelle; this to Prague, that to Vienna," nourished the warfare of the heart by daily ministrations of sense. The eye that watched for the gleams of lance or helmet from the hostile frontier, the ear that listened for the groaning of wheels, made the highroad itself, with its relations to centres so remote, into a manual of patriotic duty.
