Promptly as he acts, however, he is only in time to repair, not to prevent, the mischief. The rebels have already dethroned Louis and imprisoned him at St Martins in Tours, making Acelin of Rouen, son of Richard, Emperor. William makes straight for Tours, prevails on the castellan of the gate-fortress to let him in, kicks--literally kicks--the monks out of their abbey, and rescues Louis. He then kills Acelin, violently maltreats his father, and rapidly traverses the whole of France, reducing the malcontents. Peace having been for the time restored at home, William returns to Rome, where many things have happened. The Pope and Galafre are dead, the princess, though she is faithful to William, has other suitors, and there is a fresh invasion, not this time of heathen Asiatics, but led by Guy of Germany. The Count of Orange forces Louis (who behaves in a manner justifying the rebels) to accompany him with a great army to Rome, defeats the Germans, takes his _faineant_ emperor's part in a single combat with Guy, and is again victorious. Nor, though he has to treat his pusillanimous sovereign in an exceedingly cavalier fashion, does he fail to have Louis crowned again as Emperor of Rome. A fresh rebellion breaking out in France, he again subdues it; and strengthens the tottering house of Charles Martel by giving his own sister Blanchefleur to the chicken-hearted king. "En grant barnage fu Looys entrez; Quant il fu riche, Guillaume n'en sot gre," ends the poem with its usual laconism. [Sidenote: _Comments on the_ Couronnement.]
