The Letter about the charitable behaviour of l'abbé Roux, curator of the Quinze-Vingt hospital during the June Days Uprising (1848). On the barricades, he notably promised to give bread and wine to the people of the Faubourg St-Antoine. As Sauvageot is a friend of Roux, he collects money for the food distribution and asks Hugo and Drouet to take part in.
David-Sauvageot is unidentified. A French writer, perhaps his son, was also named A. David-Sauvageot (1856-1899).
