Nope, still cold, and once you guessed the General the Fictional character will be rather obvious too.

Another hint, he led a campaign against powerful empire, managed to secure a victory but due to differences in power and the incompetence of people in his homeland he had to retreat to protect his homeland. In the end he lose because of various reason not on the enemy territory but on his own homeland.

Later he tried to secure another army to launch another siege but his homeland found his ambition to be dangerous hence he got exiled.. in the end he spent his whole life trying to take down his enemy, hence he's something akin to avenger..
