I'm pretty sure it's said that she escaped after Heinrich almost-but-not-quite killed Alice the 8th in order to prevent all the "horrors of Black Alice's reign" and whatnot from happening again in the future.

So the answer to your predicament: Tamamo came back 500 years ago, Monster Wars are confirmed to have happened at least 1000 years ago. Therefore Tamamo wouldn't be around for whatever happened 300 years after that.
