Like many others countries in the Northern Realms, the Kingdom of Kaedwen maintains a large and well-trained army, full of valorous commanders and brave soldiers able to tolerate the terribly cold weather of the terrain.
Although the Kaedwenian soldiers are not the best swordsman of the Northern Kingdoms, they're without a doubt the best in the use of siege weapons and cavalry units.
The "crème de la crème" of the Kaedweni Army was the Dun Banner, a cavalry unit characterized by soldiers wearing beaver cloaks and caps. When the Nilfgaardian Army invaded the kingdom of Aedirn, the unit came to help their neighbors, succeeding in freeing the Lormark. Although King Henselt of Ard Carraigh considered his soldiers as "liberators", it was attested that the treatment reserved by the Kaedwenis to the inhabits of the Lormark was even worse than that of the Nilfgaardians. Later then, during the Peace of Cintra, the Lormak was returned to King Demavend III of Aedirn.
In 1263, during the First Northern War, the Kaedwenian Army, along with the forces of Aedirn, Redania, and Temeria, faced the invading Nilfgaardian Army in Lower Sodden, during the Battle of Sodden Hill. The northern armies were under the united leadership of King Vizimir II of Redania, and were successful in halting the Nilfgaardian invasion. While many were lost in the battle, in the next couple of years, the defending soldiers left in Kaedwen were frequently attacked by Scoia'tael forces, and lost significant numbers, as well as Kaedwenian fortresses the army protected.
In the same year, King Henselt and Vandergrift marched again to the Lormark and camped his army in the surroundings of the city of Vergen, which he later started besieging. This was the beginning of a bloody conflict that would last over three years.
