 With the help of some miners , John and Kanyenke bring down large rock bridges to stop the Russians ' large cannons from getting through . John then sends Kanyenke and the remainder of his mercenaries back east as he plants explosives to cause an avalanche and bury the Russians in the mountains . In the end , as John is setting up the dynamite , Warwick and several Boneguard approach him . Warwick attempts to kill John but John uses a barrel of gunpowder as a shield ( knowing that Warwick won 't risk detonating it by shooting at him ) , jumps to the trigger , and pushes it , detonating the mountainside ; killing himself , the soldiers , and Warwick ; and causing an avalanche . The avalanche buries the Russians and sets the Circle of Ossus back so far that they cause no problems for many years .
