The problem with time travel is that you are never really sure of what happened, even if you experienced it yourself. As battles were fought, each side would travel back in time to account for the most recent strategy of success. This lead to millions of sentients dying over and over again. Each side kept traveling backward and forward trying to manipulate already fought battles for their own benefit. That's what made it the great time war.
