How do I beat the white walkers if the war of dawn fails?

[Kathandis]

So Im playing as Willas Tyrell and I married Sansa stark pressed her claim for the North and the riverlands had Daenerys killed managed to get a Tyrrell as Lady paramount of the westerlands and broke free from the Iron throne along with my Wife Sansa and now rule as the incapable kind of the Reach. (My ruler took a head blow during ramsays rebellion which was before a faceless one took out ramsay.) One problem the Nights watch lost the war of dawn probably do to the boltons and various riverlands lords rebelling and taking the Norths time and now the White walkers are slowly devouring the north and growing stronger. They were manageable at first but after these many wars the Reach`s man power is dwindling so Is there a way to take out the white walkers for good or should I try and flee to Essos? Im also starting to doubt its even possible to win at this point as they just immediately declare war again and get their troops back but I would love to know if I have to restart or not cause I would rather salvage my current save.

start getting together some money and settle in essos cause you guys are already dead. soon there will be a big great WINTER over westeros. Luckily they don't seem to have boats

You could always just cheat the titles up to the wall into your hands, then dish them out and, I assume there's a decision or events to restore the watch and put everything back to normal.

You don't. You GTFO to Essos as soon as possible. If you have the war of conquest ambition, now is the time. Or, if you cheat, you could use console commands to make them lose every war they start by imprisoning their ruler.

You become Azor Ahai, grab lightbringer and give all your soldiers dragonsteel.

Simple!

You are dead, I saw the event unfold while playing essos republic (who just happily minding it's own business)

So best to run away westeros is lost all will become others or whitewalker or ruins

Winning is not that hard. I play as Daenerys (war of five kings bookmark), I've reconquered Westeros and married Aegon. When my dragons were old enough, I've tamed Drogon and gave Viserion to Aegon. When White Walkers attacked me, I used Unsullied (from events at the start of bookmark) and Dragons, easily won (with one battle - 8000 vs 22000 white walkers ). Then, I've declarated war of the dawn on them, again, one or two battles, and poof - they were no more So my advice? Get a dragon!

What are the requirements for declaring a War for the Dawn? Is it even theoretically possible if the entirety of Westeros falls?
