On April 17, 1637, he gave a dinner-party, to which La Ruelle, Abbé de Mouzon, and other guests were invited. When La Ruelle arrived, accompanied by a young manservant named Jaspar, Warfusée gave him a jovial greeting. Then, noticing Jaspar, he exclaimed, 'Ah! there's my good friend; I know him well,' and showed the way to the kitchen, saying: 'You must enjoy yourself to-day, and drink to the health of Burgomaster La Ruelle.'
The company sat down to dinner in a room on the ground floor, the windows of which had iron bars across them, and opened on a courtyard in the middle of the building. Count Warfusée sat next the door, with M. Marchand, an advocate, beside him. La Ruelle and the Abbé were on the other side of the table. Baron de Saizan, a Frenchman, and several other gentlemen were present, and also some ladies, among whom were the Baroness de Saizan and Count Warfusée's four daughters. Every one was in the highest spirits. The Count declared he felt so happy that he intended to get drunk, and invited all the rest to follow his example. Calling for big glasses, he challenged de Mouzon to a revel. The Abbé proposed the health of the Most Christian King; and this toast was duly drunk, the gentlemen rising, and uncovering their heads.
During the first course the merriment of the party increased; but suddenly the Count's manner changed, and one of the company was bantering him about his gravity, when, as the servants were bringing in the second course, his valet de chambre came and whispered in his ear. Warfusée nodded, and immediately twenty soldiers, each holding a drawn sword in one hand and a firelock in the other, entered the room, bowed, and surrounded the table. The guests supposed that this was some pleasantry devised for their amusement; and La Ruelle asked his host what it meant. 'Nothing,' answered Warfusée—'do not move;' but as he spoke a band of Spaniards appeared at the windows, and levelled their muskets through the bars. Warfusée, pointing to Jaspar, who was waiting on his master, ordered the soldiers to remove him. He was seized and turned out of the room. The Count then shouted, 'Arrest the burgomaster!'
'What? Arrest me?' exclaimed La Ruelle, rising and throwing his napkin on the table.
'Yes, you,' replied Warfusée, 'and Abbé de Mouzon, and Baron de Saizan also.'
The soldiers took La Ruelle, and dragged him out; and Warfusée, shouting at the top of his voice, declared that he was acting under the orders of the Emperor, and of His Royal Highness the Bishop. They had, he said, borne long enough with the intrigues of the French, and the authority of the Prince must be re-established. A scene of the wildest confusion followed. Warfusée rushed into the courtyard, and loaded La Ruelle with insults. 'Ropes, ropes for the burgomaster!' he shouted. 'Ah! you traitor! your heart is in my hands today. See, here are the orders of the Prince'; and he pulled some papers out of his pocket. 'Make your peace with God, for you must die.' Jaspar, the servant, who was standing near, already bound, is said to have exclaimed, when he heard these words, 'Oh, master, have I not always said what would happen?'
All in vain La Ruelle begged for mercy. Two Dominicans, sent for to shrive the victim, implored the Count to pause; but 'Kill him, kill him! Make haste. Lose no more time,' was his answer to their entreaties, and to those of his own daughters, who besought him, with tears, to spare the unfortunate man's life. Some of the soldiers refused to touch the burgomaster, and told Warfusée to his face that they were not assassins. But at last three Spaniards drew their daggers, and stabbed La Ruelle repeatedly till he was dead.
His cries were heard in the room where De Mouzon, fearing that his own last hour had come, was waiting with the other guests under guard of the soldiers. The Dominicans entered; and all were crowding round them, pouring out confessions and clamouring for absolution, when Warfusée came to the door, and told them that the burgomaster was dead, and that he had died repenting of his misdeeds, and seeking forgiveness from God, the Emperor, and the Bishop. Having said this, he went away again.
In the meantime a report had spread through the town that something unusual was happening. It was said that a band of Spanish soldiers had been seen to cross the Meuse, and go to the Count of Warfusée's house, where the burgomaster was known to be dining that day; and every one suspected that they had been sent to arrest La Ruelle, De Mouzon, Warfusée, and their friends. So a cousin of the burgomaster's went to find out if this was the case. When he reached the door of the house he found a crowd of people, who told him they had heard cries from within and the clash of arms, and that there was a rumour that the burgomaster had been murdered.
