A cavalry charge in the dark into a overwhelming mass of previously killed warriors probably ends the way it did. A simple infantry square used to mangle cavalry charges 200 years ago, so I’m guessing it would not work against five zillion dead people.
Logically, and I’m using the word loosely, last night really had to end the way it did.
If I have an army of 10 dead people and you have an army of 10 live people, I’m going to win and win quickly.
You have to kill my dead soldiers in one of two particular ways. Both are really inconvenient. I can kill your soldiers in any fashion I would like. If I kill one of yours, the game is now 11 to 9. Two, and it becomes 12-8.
My soldiers never get tired. They don’t care about the weather or the time of day. They don’t need food, water, clothes, shoes, tents, sleep or any sort of provision whatsoever. Your soldiers need all of those things every few hours.
And given the numbers game above, you’re going to lose in hours. I don’t need replacements or reserves - I make those every time I kill one of yours. You need both.
Basically, the only way to end that battle is how it did last night - with a home run. If not for that, the show’s pretty much over.
Either that, or Jon Snow learns that the night king is actually his father and then after some soul searching, they form an unlikely alliance and defeat Cersei. And then we can have some unsatisfying prequels in a few years.
