800 vs 1000 isnt that big a difference, though.
I remember a match in Rome: Total War where i was outnumbered 3 times lol, and i came out on top.
I hid my soldiers in a forest, so only my general was visible. That led to a rush by the enemy. When they got close enough, my archers stood up and started firing at the enemy, so they started suffering casualties.
Then they got closer, my infantry stood up and threw their javelins, wiping out half of some units, then they just charged them, general around the back and into their side, first units started to rout. Then that panic slowly spread through the entire enemy army while the rest of my legionaires were holding out as long as needed. Tough battle, but i made it, and those moments are truely epic
Cool little detail then sometimes pops up on the campaign map, pointing out places of epic struggle against all odds wich were won. Just like you just made history, like we still know about some battles from medieval times etc.
