Evelina

According to Grace Dalrymple Elliott's "Journal of My Life During the French Revolution" she shared a cell with Madame du Barry:

"I did not stay at St. Pelagie long. It was in June, I think, that I left it; but cannot be exact, as the months were different in France, and I never really knew what month it was. Poor Madame Du Barri came there before I left it. She was very unhappy. She used to sit on my bed for hours, telling me anecdotes of Louis XV and the Court. She talked to me much of England and of the Prince of Wales, with whom she was enchanted. She regretted much ever having left England. She dreaded her fate.

Indeed, she showed very little courage on the scaffold; yet, I believe, had every one made as much resistance as she did, Robespierre would not have dared to put so many to death, for Madame Du Barri's screams, they told me, frightened and alarmed the mob. She was very good-natured, and during the time I lived in the same prison with her I liked her much."

Much of Grace Elliott's Journal is believed to be fictional, and sadly this part probably isn't true. However, Jeanne du Barry's traumatic execution really did have that effect on the mob.
