Napoleon, Berthier and the Polish colonel in their undies
I tend to be scattered, and I want to finish Countess Potocka's portraits of the Napoleonic people she met, but I found this amusing little tidbit from the war of 1812 (a time not rife in amusing tidbits), and I could not resist. Not my best translation, but I might be forgiven; I will let readers judge for themselves.
Le 23 juin, nos cavaliers (6ème régiment de lanciers polonais) reposaient encore dans leurs bivouacs, lorsqu'une voiture de voyage, attelée de six rapides coursiers et arrivant au grand trot par la route de Koenigsburg, s'arrêta tout à coup au milieu de notre camp; elle n'était escortée que de quelques chasseurs de la garde, dont les chevaux étaient haletants et harassés de fatigue.
La portière s'ouvrit et l'on vit Napoléon sortir avec vivacité de la voiture, accompagné du prince de Neufchâtel [sic] : aucun des aides de camp, aucun officier d'ordonnance ne se montraient. Peu après, le général Bruyères arriva seul, au galop. Napoléon était vêtu de son uniforme de chasseur de la garde ; il paraissait très fatigué du voyage, et ses traits offraient l'empreinte de la préoccupation. Quelques officiers parmi lesquels je me trouvais, ainsi que le major du régiment (Suchorzewski), accoururent. Tout en continuant ses interrogations, il demanda à changer d'habits, voulant prendre l'uniforme polonais; car il avait été convenu, ou plutôt ordonné, qu'aucun militaire français ne serait montré aux Moskowites [sic; this word is used to mean “Russians”]. Il mit donc bas son habit, le prince de Neufchâtel fit de même, Suchorzewski, moi et le colonel Pagowski, qui venait d'accourir, suivîmes son exemple, ainsi que le général Bruyères; de sorte que nous nous trouvâmes cinq ou six personnes en chemise au milieu du bivouac, entourant l'Empereur, et chacun de nous tenant son uniforme à la main. Les Polonais offraient les leurs aux Français, ce qui présentait un tableau singulièrement original. De tous nos uniformes, la redingote du colonel Pagowki et son bonnet de police convinrent le mieux à l'Empereur. [...] Tout cela fut l'affaire de quelques minutes. Berthier se revêtit aussi d'un uniforme polonais. On amena promptement les chevaux du colonel. Napoléon monta sur l'un d'eux et Berthier sur l'autre. [Here Napoleon and Berthier reconnoiter the area]. Après avoir terminé cette reconnaissance, Napoléon revint à notre bivouac.
Au retour de Napoléon, nous remarquâmes un changement visible sur sa figure; il avait l'air gai, et même d'une humeur enjouée [...]. On lui apporta d'abord quelques rafraîchissements, qu'il mangea au milieu de nous, sur la grande route; il semblait prendre plaisir à son travestissement, et nous demanda, à deux reprises, si l'uniforme polonais lui allait bien. Après avoir déjeuné, il nous dit en riant: "A présent il faut rendre ce qui n'est pas à nous." Puis il ôta les vêtements qu'il avait empruntés, reprit son uniforme de chasseur de la garde, remonta en voiture, accompagné de Berthier, et partit brusquement. [...]
On June 23, our horsemen (the sixth regiment of Polish lancers) were still resting in their encampments, when a traveling coach, harnessed with six speedy steeds and coming at a rapid trot from the Koenigsburg road, stopped suddenly in the midst of our camp; its only escort consisted of a few chasseurs from the Guard, whose horses were worn out with exhaustion.
The door opened, and Napoleon briskly came out of the coach, accompanied by the Prince of Neuchatel; none of his aides de camp, none of the officers of his personal suite were in evidence. Shortly thereafter, General Bruyères arrived alone at a galop. Napoleon was dressed in his uniform of a chasseur de la garde; he seemed quite tired out from his travel, and his features gave every indication of concern. A few officers, myself included, as well as the major of the regiment (Suchorzewski), came running. [Here Napoleon asks many questions about roads and the like.] In the course of questioning us, he asked to change his clothing, as he wished to wear a Polish uniform; it had been agreed, or rather it had been ordered, that no French military man would be seen by the Muscovites. Therefore he removed his uniform, the Prince of Neuchatel followed suit, Suchorzewski, myself, and Colonel Pagowski, who had come running, followed their example, as well as General Bruyères; so that five or six persons found themselves in their chemise at the centre of the bivouac, circling the Emperor, and each of us holding his uniform in his hands. The Poles were offering theirs to the French, which presented a singularly novel spectacle. Out of all our uniforms, Colonel Pagowski's coat and his bonnet de police [a soft campaign hat?] suited the Emperor best. [...] All this took but a few minutes. Berthier also dressed in a Polish uniform. The colonel's horses were promptly brought forth. Napoleon mounted one and Berthier the other [...]
[Here is a description of how our two false Polish officers go off with the help of a real Polish officer as a guide, to have a look at the terrain on the other side of the Niemen, this being the day before the Grande Armée crossed it]. After completing this reconnaissance, Napoleon returned to our bivouac. [He now proceeds to ask many more questions.]
After Napoleon's return, we noticed a visible change in his face; he seemed cheerful, and even is a playful mood [...]. Some refreshments were brought to him, which he ate in our midst, on the main road; he seemed to enjoy his disguise, and asked us, twice, whether the Polish uniform suited him. After his meal, he told us laughingly: "Now we must give back waht is not ours." He then took off the garments he had borrowed, dressed again in his uniform of chasseur de la garde, climbed back into his traveling coach, accompanied by Berthier, and was gone in an instant.

So there you have it. Napoleon, the very proper Berthier, and hapless General Bruyéres, along with the Polish regiment's colonel, its major, and another officer of unspecified rank, stripped down to their chemise in front of a no doubt startled regiment of Polish lancers. For those Polish lancers lucky enough to survive this disastrous campaign, this episode must have been much told and retold once they made it back home ("Grandpa, tell us again about the time that you saw Napoleon in his underwear in the middle of your camp.") Not counting the endless jokes made sotto voce as soon as Napoleon's traveling coach was out of sight.
Now what remains untold is whether General Bruyères was left standing there in his chemise for however long Napoleon and Berthier's reconnaissance took; nor is there any mention of Berthier changing back into his usual uniform, so maybe he left still dressed as a Polish officer. Who knows, as one who gave many brilliantly organized and attended masked balls, Berthier might have had future plans for his unaccustomed outfit. Since there is no mention of General Bruyères getting dressed again and leaving the spot, maybe he spent the entire campaign wearing only his chemise, standing there on the western shore of the Niemen. Which, considering how the Russian campaign went, would have been the less painful choice.
