The Battle for Castle Kvatch is a quest in The Elder Scrolls IV: Oblivion. This quest is initiated by Savlian Matius. Upon reaching the chapel of Akatosh in Kvatch, he will say that the battle for Kvatch is not yet over, and that Castle Kvatch must be retaken.
Talk to Savlian again and follow him out of the chapel, fighting to the front of the castle. The castle gate will be closed; talk to Salvian, and he'll say to go back into the chapel and talk to Berich Inian. When the chapel is re-entered, three Imperial Legion troopers (two soldiers and an archer) will be there and will offer to help. They also mention how they saw the smoke from the Gold Road.
Berich won't give up the key, but will instead run downstairs into the Chapel Undercroft, where more daedra await. Follow him through back into Kvatch. If he dies, take the key from his pocket and head through the ruined city to a destroyed tower.
Inside on the ground, there is a circular hatch that leads to a short underground passage. Run through, exit and come up between two gates. Open the gates by turning the wheel at the top of the stairs. Salvian and more guards will come through and help fight more daedra. Afterwards, head inside the castle.
Inside the Castle Great Hall are more daedra as well as scamps. Fight them with the help of the soldiers and then Salvian will wait while Count Ormellius is searched for. Head straight ahead and continue through another part of the Great Hall to the Count's Quarters. Kill the daedra that are there and check the Count's body.
In the second to last room, there will be a lot of level-dependent daedra. A journal message will appear to take the Count's ring and return it to Salvian.
