TIL! So if you replace "whence" with "from where", is "go back to from where you came" grammatically correct?
Also, you're answer prompted me to search, and I found this neat answer about the history of whence vs from whence; apparently from whence has been (mis)used for centuries!
Perhaps I should have been more clear. I didn't mean it's a direct substitution for "from where", just that that's its meaning. A grammatical translation of the sentence would be "go back to where you came from".
