On the occasion of the marriage of the Emperor’s Grand Equerry, which took place during the Carnival, and the festivities in connection with which lasted several days, Bassompierre arranged with Rossworm and six other nobles to parade the town on horseback, masked and splendidly dressed. As they were passing the Town Hall, some constables came up to Bassompierre and Rossworm, who, preceded by their pages bearing their swords aloft, were riding at the head of the party, and informed them that the Emperor had forbidden anyone to pass through the town masked. They, however, pretended that they did not understand Sclavonic, and rode on. No attempt was made to stop them, but, on their return, they found chains stretched across all the streets leading to the square in which the Town Hall stood, except the one by which they entered, and, so soon as they had passed, chains were stretched across that also. Then a whole company of constables appeared upon the scene, and, beginning with the hindmost of the party, seized their companions, who, not having brought their swords with them, were unable to offer any resistance, and haled them off to prison. Meanwhile, Bassompierre and Rossworm had taken their swords from their pages, but they did not draw them. However, when one of the constables attempted to seize the bridle of Bassompierre’s horse, Rossworm struck him on the hand with his sheathed sword, and, the blade, breaking through the scabbard, wounded the man somewhat severely. They were immediately surrounded by more than two hundred police, but, drawing their swords, they contrived to prevent them from closing with them and dragging them off their horses, though not without receiving a volley of blows on their backs and arms.
