I recently saw this rather tongue-in-cheek graphic:

Now I have no idea regarding the veracity of the above, but assuming it is somewhat true it begs the question: If Europeans didn't eat them, what did people do with captured (i.e still alive) elephants once their masters would have been killed and presumably there wasn't many people with expertise of elephant handling on the European side. One would also think that often the elephant would find itself in a non-native habitat and so couldn't just be left to their own devices.
Is there any historical record of this rather niche question?
