“Gentlemen,
You have undertaken to cheat me. I won't sue you, for law is too slow. I'll ruin you.
Yours truly,
Cornelius Vanderbilt”

— Cornelius Vanderbilt

Said to be the entirety of a letter to Charles Morgan and C. K. Garrison, quoted in an obituary, "Commodore Vanderbilt's Life" (5 January 1877) New York Times. Stiles, in The First Tycoon (2009) doubts this. He notes that there is no earlier source, that Vanderbilt was no stranger to the courts, and that he never otherwise closed letters with "yours truly."

“Gentlemen! I too have been a close observer of the doings of the Bank of the United States. I have had men watching you for a long time, and am convinced that you have used the funds of the bank to speculate in the breadstuffs of the country. When you won, you divided the profits amongst you, and when you lost, you charged it to the bank. You tell me that if I take the deposits from the bank and annul its charter I shall ruin ten thousand families. That may be true, gentlemen, but that is your sin! Should I let you go on, you will ruin fifty thousand families, and that would be my sin! You are a den of vipers and thieves. I have determined to rout you out, and by the Eternal, (bringing his fist down on the table) I will rout you out!”
