Charlotte Corday, a communist?

In The Inimitable Jeeves, Comrade Bingo chapter, Charlotte Corday Rowbotham is the communist fiancée of Bingo Little.

I find this inconsistent with the fact that the real Charlotte Corday of the French Revolution was a Girondins´ sympathizer.

The Girondins were not communists and were sort of centrist moderates, according to what I have read on the matter.

Was Plum Wodehouse confused about this?

Did he think that all French revolutionaries were communists?

At that time the concept of Communism was a vague idea and the Communist Manifesto was published in 1848.
