Legend of Berthe

A Sire de La Roche, who only had an only daughter, Berthe, to inherit his powerful estate, organised a great tournament at the castle. The hand of the rich heiress would go to the knight who, in a fair fight, emerged victorious over all rivals.
The first knight to appear was the Comte de Montaigu, a colossus, proud of his strength, who had never been thwarted by an opposing lance.
So no other champion came forward.
Yet it was to the Countess Alix de Salm that the Comte de Montaigu had pledged his faith.
When the time limit was almost reached, a horseman entered the courtyard.
What a singular opponent!
He was a tiny knight, almost a child, and at the sight of this puny champion, the Comte de Montaigu was seized with a tremendous fit of laughter.
In front of the knights and ladies, the unequal combat began.
With a tremendous clash of iron and the heavy gallop of his battle horse, the Comte de Montaigu rushed against his weak opponent, who was armed only with a light harness and his horse was not protected by any armour. With marvellous dexterity, the supple mount took off with a single leap and avoided the Count's violent impact.
In an instant, the Count had turned around and was marching again, this time more slowly and methodically, against his skilful rival. But no matter how many times he struck, it was all to no avail and he was getting terribly hot. Moderating his horse's speed, the little knight stopped and waited in an upright, defiant stance.
Taking advantage of this moment, the Count came running; the sword of the colossus whirled in the air and, with a flash of steel, came down with a hiss on the imprudent youth...
But the little knight was already gone, while the Count's heavy mass, swept along by his momentum, lost its balance and was knocked off his feet, crashing to the ground with a clash of shattered iron". The little knight, inserting the thin blade of his light sword under the joint of his helmet, cut the throat of the formidable Count with a single blow...
A moment later, the happy father led the newly-weds up the dungeon to the bridal chamber.
Early the next morning, impatient to see and share the happiness of the young couple, the father waited in the courtyard of the castle. But the sun kept rising without the father seeing them appear. Tired of this long, fruitless wait, he climbed the steps of the keep, ran to the door of the bridal chamber and knocked. No answer... Powerless to suppress his paternal concerns, the father pushed open the door; it yielded, but the room was empty and the window open. At the bottom of the abyss, on the rock, on the banks of the Ourthe, two dots stood out: one was black, the other white.

The mysterious Chevalier was none other than the Countess Alix de Salm who, under this disguise and having made a pact with the devil, had taken revenge on the Count de Montaigu and the beautiful Berthe de La Roche...
