Quand je serai parti... vous vivrez encore (English title: The Long Winter) is a 1999 Quebec historical drama film. Directed by Michel Brault, it is a partly fictionalized account of the Lower Canada Rebellion of 1837 and 1838 which sought to make Lower Canada, now Quebec, a republic independent from the British Empire.
The main protagonist is Patriote François-Xavier Bouchard. The latter comes back to Lower Canada in the autumn of 1838 after having escaped to the United States (as a number of Patriotes did indeed), after the first uprising, in that year. As soon as he returns, despite the exhortations of his family, he joins François-Marie-Thomas Chevalier de Lorimier for another attempt. Following a hasty trial, Bouchard, Chevalier de Lorimier and others are sentenced to death.
I was looking for Laura Ingalls Wilders book The Long Winter
