My updated variant:
Bassicaly:
Rampage through the countryside, so even in their so-called victory these mortals will still have to deal with corruption of their lands In details
Krlnkir Yrlvnt 1) Wage strategical warfare. Destroy infrastructure, food producing, industry, small settlements, travellers, small squads, avoid really big fights:
we just can't leave now, eat their beloved caws, burn their villages, corrupt water, let them starve to death in that damned city.
Use our advantage in mobility to avoid hard fights, it's like war with aviation against someone, who has no effective AA guns (bows and arrows aren't effective).... move from village to village, from helmet to helmet, from field to field, from caravan to caravan, from bridge to bridge, from mountain pass to mountain pass. Carpet bombing it is. Also create more red imps from all that chaos and destruction, they are ideal for that type of warfare. Also corrupt birds to act like Hitchcock's birds, under our command
2) Carefully learn about that good thing
3) Don't get too close to the city (max 5km)
The Realm Long term orders:
Transfer resources to the CFM (construction material, firewood, small animals, food) : 10 resources per week

Dal'Kahh the Avaricious 1)Commands an operation without our interference or aid
2)Don't do rush assault thing, weaken the enemy by catapults, tunneling, commando attacks, then start an assault
3)Be ready to retreat to Akataki if scouts inform him about big reinforcments nearby (weak away or closer)

So, nobody's considered just flying high and raining fire (lit. rain of fire) down on them to break their forces up a bit, then?
We'll still have to deal with archers, priests and that misterious force, so I think: no
