In Alan Palmer’s book: Napoleon in Russia, he recounts how General Philippe Paul de Ségur entered Moscow to prepare the Kremlin to receive Napoleon. He tried to sleep in an armchair, but around midnight, got up and looked out a window and saw: “Some distance away, in whatever direction I looked, there were flames leaping up.”
Sergeant Bourgogne with the Imperial Guard was with some of the first troops to enter the city. In order to prevent looting, they were not allowed to leave the Kremlin square when dismissed. Bourgogne said: “We went to the houses in the square to ask for food and drink, but as we found nobody in them we helped ourselves.” The same thing was going on all over Moscow.
The commander of the Guard sent Bourgogne and his men off in search of pumps and hoses to fight the flames (they had all been destroyed by the Russians). Men with torches were passing them by, but they were allowed to pass unchallenged. His patrol eventually did round up some incendiaries, but Bourgogne himself allowed three to escape.
One of the escapes happened in this way: Bourgogne’s men had rounded up 32 prisoners and he was in command of the rear guard. As they went, he noticed one crying like a child, and saying repeatedly “Mon Dieu! I have lost my wife and son in the fire!”
The man turned out to be from Switzerland and had been working as a French and German tutor in Moscow. Bourgogne felt sorry for the man and offered to help him look for his family. The man recognized his house by the large stove standing in the burned wreckage. The column stopped at this time due to the street being blocked by flames. The man soon found his wife and son, both dead in the cellar of the house.
