Jakob Walter’s account of his stay in Moscow is short, but he did write about how provisions could be bought in the “German suburb” where the Württemberg corps stayed for three weeks.
“Here one could find and buy provisions; for each soldier was now citizen, merchant, innkeeper, and baker of Moscow. Everyone tried to dress as much as possible with silks and materials of all colors. Only tailors were lacking; silks, muslins, and red Morocco leather were all abundant. Things to eat were not wanting either. Whoever could find nothing could buy something and vegetables in sufficient quantity stood in the fields. Particularly was there an abundance of beets, which were as round and large as bowling balls and fiery red throughout. There were masses of cabbage three and four times as large in size as cabbage heads that we would consider large. The district called Muscovy is more favored in agriculture and climate, and more civilized than the regions toward St. Petersburg than those through which we had come. It was still good weather, and one could steep warm enough under a coat at night.”
Negotiations for a Russian surrender had not gone according to plan and Napoleon decided to leave Moscow and head west in search of winter quarters. Walter describes the evacuation: “After we had been citizens of Moscow for four weeks, we lost our burgher rights again. Napoleon refused the peace treaty proposed to him, and the army which had advanced some thirty hours’ farther on had to retreat, because the Russian army stationed in Moldavia was approaching. Now it was October 17, and Napoleon held an army review and announced the departure for October 18, early in the morning at 3 o’clock, with the warning that whoever should delay one hour would fall into the hands of the enemies. All beer, brandy, etc., was abandoned and whatever was still intact was ordered to be burned. Napoleon himself had the Kremlin undermined and blown up. [Note: The Kremlin was not blown up] The morning came, and each took his privilege of citizenship upon his shoulders and covered it with his coat cape of strong woolen cloth, and everybody had bread pouches of red Morocco leather at his side, all had an odd appearance as they set out; they filled, as far as it was possible, everything with sugar and the so-called Moscow tea in order to withstand the future misery.”
The Grande Armée did not actually leave Moscow until the 19th. Perhaps Walter had his dates wrong or merely remembered the original plan for departure.
