Chanson de l'Oignon but you're freezing in Russia (and have no onions)

tfw the Austrians took all your onions “Supplying the army in full became an impossibility. The lack of grass and feed weakened the remaining horses, almost all of which died or were killed for food by starving soldiers. Without horses, the French cavalry ceased to exist; cavalrymen had to march on foot. Lack of horses meant many cannons and wagons had to be abandoned. Starvation and disease took their toll, and desertion soared. Many of the deserters were taken prisoner or killed by Russian peasants. Badly weakened by these circumstances, the French military position collapsed.“ -
