Has anyone ever "deciphered" a paragraph?

I said: "It is perfectly possible for a cipher to decrease entropy."

You said: "It would be of great interest to have a historical example of this."

I provide you with a historical example illustrating how it is perfectly possible for a cipher to decrease entropy.

Mark, could you please post the historical example here, on a public forum, so that we can all follow along with the claims that you are making here, on a public forum. Thank you.
