Concretely, you actually did only win because of the ice. Darka had been increasing its borders since your arrival, and unless you would have brought several armies from the south you (CE) would have gained 0 progress in this war since all you managed was to loot some rurals which Darka reclaimed before your next arrival.
You hear that, jaune? Darka was growing bigger! CE made 0 progress! Darka was obviously
#winning!
It was a good thing that the Devs saved us.
Now however CE is attacking and looting a broken, divided and crushed realm. The honour-points for CE keeps on collecting I suppose. From what I hear, CE is refusing to accept the diplomatic surrender of Darka, most likely to build the idea that CE somehow managed to beat Darka by force. If this is not caused by ooc inactivity I consider it truly despicable and dishonourable warfare by a realm trying to manufacture a victory out of falsehood.
You should get some better sources, preferably ones that won't lie to you.
