If you actually read both links I provided, you might find them interesting. Also, why shouldn't I quote r/AskHistorians when discussing historical events?
r/AskHistorians has some of the highest quality research you're going to find on the internet, at least if you're not a history major yourself. The mods there are amazing, and the posts usually have sources you can look into yourself.
If you haven't browsed it before, I highly recommend looking into it.
We may never know.
