Continuing Bannerlord...
Why haven't gone this far with the Khuzaits before, I've discovered a fun I didn't know there was before.
I built up a small all cavalry warband of horse archers and lancers then signed a mercenary contract with the Western Empire in a war against the Northern Empire, at first I wasn't having fun because we were losing the huge army battles and I'd lose more troops because of the west Imperial's failures...
... then I stopped being part of the armies and tried out raiding behind enemy lines and it turns out the Khuzaits are perfect for this. In particular I've been targeting villages that produce horses so that I can trample over the local militia peasants then steal all the horses, horses being important actually as a requirement to upgrade cavalry troops and my force is all cavalry.
The raiding also disrupts and distracts the Northern Empire which actually helped the Western Empire start winning their bigger battles.
I'd even fight enemy warbands too, if too big or strong my 100% cavalry force is fast enough to easily out run them, but even if I'm outnumbered by 30 to 40 but they have very little cavalry and mostly infantry then I'll actually take them on and in battle I'd just have my horse archers follow me and I'd just circle around the enemy group and whittle them down one by one while taking little to no casualties myself, and if the battle drags on and my horse archers run out of arrows then I just retreat from the battle to reset it, end up in the overworld map again and then just attack again and enter round 2 with full arrows again and a much smaller enemy than before.
And because the enemy warband is larger than mine I get a bunch of renown and influence when I defeat them, and I've been lucky too and have been able to take several lords prisoner which I hold for ransom.
I entered the war with just 6,000 denars and 5 horses in the inventory, the war ended with me now having 37,000 denars and over 40 horses. I'd call that a good war campaign for me.
Edit: And I just made a whole 'nother whopping
37,409 denars from selling all the loot I picked up through my raiding campaign, now totaling 75k!
