Doesn’t sound like a great strategy. At this point we don’t know what can kill the night king. So with the night king away down south, I don’t see how the remaining walkers and whites can win the war at
winterfell.

I would think the two dragons and all the other fire weapons would devastate the zombi whites. The walkers will drop like fly when they are stabbed with the unsullied dragon glass spears. At most there are 95 walkers. Every weapon being used has dragon glass. I don’t see 95 walkers surviving. Do the walkers do much fighting anyway. Are they trained in sword play. Seems to me they just watch the whites do all the killing. Romberg, fat Sam ran up on a walker. One stab destroyed it. Trained darthraki and unsullied should destroy 95 walkers easily.

The walkers would have to stay back while the whites attack. That’s where the dragons and fire weapons come into play.

It’s the night king that could change the war if he stays
