The Belgians are very fond of music, and it so happened that there was a concert to be given that evening, to which I and my officers had been invited, as was M. de Laussat, the prefect of the department.

We agreed that we should go there as usual, which was the right decision, for we were received with cordiality, at least on the surface. While talking to the nobles, who had been behind the disturbance, we put it to them that it was not for the populace to decide by rebellion the fate of Belgium, but rather for the contending armies; and it would be folly on their part to incite the workmen and peasants to shed their blood, in order to hasten by a few days a solution which would presently become evident.

An elderly Austrian general, who had retired to Mons, his birthplace, then said to his compatriots that they had been wrong to plot the seizure of the garrison, for that would have resulted in much damage to the town, as no soldiers would lay down their arms without a fight. They all agreed that this assessment was correct, and from that day forward the garrison and the townsfolk lived peacefully together as in the past. The people of Mons even gave us a few days later a striking demonstration of their support.

As the allied armies advanced, a crowd of partisans, mainly Prussians, disguised themselves as Cossacks, and driven by the desire for plunder they grabbed anything which had belonged to the French administration, and had no hesitation in seizing the goods of even non-military French citizens.

A large band of these imitation Cossacks, having crossed the Rhine and spread out on the left bank, had reached as far as the gates of Brussels, and had pillaged the imperial chateau of Tervueren, from where they took all the horses of the stud farm which the Emperor had installed there; then, splitting into smaller groups, these marauders infested Belgium. Some of them came to the department of Jemmapes, where they tried to stir up the populace, but when they did not succeed in doing so, they put this down to the fact that Mons, the principal town of the region, had not supported them because of the terror inspired by the colonel in command of the garrison. Whereupon they decided to capture or kill me, but in order not to awaken my suspicions by employing too great a number of men for this exploit, they limited the number to three hundred. It appeared that the leader of these partisans had been well briefed, for, knowing that I had too few men to guard the old gates and ancient, partly demolished, ramparts, he took his men, during a dark night, to the rampart, where the major part of them dismounted and made their way silently through the streets to the main square and the Hotel de la Poste, where I had at first stayed. However, since I had heard of the crossing of the Rhine by the enemy, I had gone every evening to the barracks, where I spent the night surrounded by my troops. It was as well that I had done so, for the German Cossacks surrounded the hotel and rifled through all the rooms. Then, furious at not finding any French officers, they set on the inn-keeper, whom they robbed and maltreated, and whose wine they drank until both officers and soldiers were drunk.

A Belgian, a former corporal in my regiment, named Courtois, for whom I had obtained a decoration as one of my bravest soldiers, arrived at this moment at the hotel. This man, born at Saint-Ghislain near Mons, had lost a leg in Russia the previous year, and happily I had been able to save him by securing means for him to return to France. He was so grateful for this that during my stay in Mons in the winter of 1814, he came often to visit me, and on those occasions he dressed in the uniform of the 23rd Chasseurs which he had once so honourably worn. Now, it so happened that on the night in question, Curtois, while returning to the house of one of his relatives where he had been staying, saw the enemy detachment heading in the direction of the hotel, and although the gallant corporal knew that I did not sleep there, he wanted to be sure that his colonel was in no danger, so he went to the hotel, taking with him his relative.

At the sight of the French uniform and the Legion of Honour, the Prussians shamefully grabbed the crippled man and tried to snatch the cross of the Legion from him. When he resisted, the Prussian Cossacks killed him and dragged his body into the street before continuing their drinking.

Mons was so large in comparison to my small garrison, that I had taken refuge in the barracks, and having arranged my defences for the night at this spot, I had forbidden my men to go near the main square, although I had been told that the enemy were there, because I did not know their strength and feared that the local populace would combine with them. But when the townspeople heard of the murder of Courtois, their fellow countryman and one regarded with affection by all, they resolved to be revenged, and forgetting their complaints against the French, they sent a deputation, comprising the brother of the dead man and some of the leading citizens, to ask me to put myself at their head in order to drive away these "Cossacks."

I was well aware that the pillage and excess at the Hotel de La Poste inspired in every bourgeois fear for his family and his house, which motivated them to expel the Cossacks as much as the death of Curtois, and that they would have acted very differently if, instead of robbers and assassins, it had been regular troops who had entered the town; nonetheless I thought it my duty to take advantage of the good-will of those inhabitants who were prepared to take up arms to help us. I then took part of my troop and set off for the square, while the remainder, in charge of the battalion commander, who knew the town well, I sent to lie in wait at the breach in the wall through which the Prussian Cossacks had entered.

At the first shots fired by our people at these rogues, there was a great tumult in the hotel and the square! Those who were not killed took to their heels, but many got lost in the streets and were finished off one by one. As for those who reached the place where they had left their horses tied up to trees in the promenade, they ran into the battalion commander, who greeted them with a withering fusillade! At daylight we counted in the town and in the old breach more than 200 dead, while we had not lost a single man because our adversaries, fuddled by wine and strong liquor, had offered no defence. Those of them who escaped into the country were caught and killed by the peasantry, who were enraged at the death of the unfortunate Curtois, who was something of a local celebrity, and who, given the name of "Jambe de bois", had become as dear to them as General Daumesnil, another "Jambe de bois," was to the working class of Paris.
