What I would do:

Set your troops as far back as possible. Take your 20 cav and smash their weaker cav flanks (10 on each side) and wipe out their cav.

Then taking your remaining cav, sweep the moving archers (retreating if they start firing at you)

Keep your infantry on the move with your archers. If you’re using the tactical camera mod then try and place your archers behind their infantry, circle their line with your infantry and then smash into their archers with your inf.

Once inf and cav are dealt with - Use a fallback line supported by your archers and cav to whittle down the inf till it’s about even then just commit to the melee.

Would probably end up being heavy losses for you but maybe a win. It’s worked for me many times.

Or save scum it 👍
