I initially thought that Sansa was the stupid naive one. She has grown up a lot, but still found herself caught up in emotion. When she stepped up to get additional support from one of the Northern families, she was shot down. You could see visibly how upset she was.
Then she sent a Raven, I assumed to Littlefinger. She knew she needed more men. She also didn't want to tell John.
There werea couple of opportunities, even in previous episodes, for Sansa to tell John. I kept telling myself Sansa was an idiot for not telling. Even if John would disapprove, they were men wiling to fight. Something John desperately needed.
Fast forward to the day before the battle. John offered out Ramsey. Ramsey is not stupid.
But what about Sansa's reaction?
She was adamant that Ramsey would 'die tomorrow'. It immediately stood out to me. More than just confidence or 'being strong'. At this point, I think she knew that the support would come.
Then in the War room. John thinking his plan. It sounded pretty good, but Sansa's shut it down. She knows Ramsey. John didn't.
They also discussed Rickon. Sansa said he was effectively dead already, even if he wasn't. She knew Ramsey 'plays games'. She knew he plays on emotions.
At this point, I firmly believe Sansa knew that support was coming. But why not tell John at this point? There was little John could to to change it if he disapproved.
We are now on the battlefield. Ramsey did exactly what Sansa thought. He teased John. He drew John out. John said himself that he needed 'them to attack us'.
But John acted like a Stark. A true Stark. And a good person. He did the right emotional thing. Taking emotions out of it though, he played into Ramseys hands.
As the battle continued, Ramsey was inadvertently killing his own. Their forces were being depleted. As were John's.
Then John is boxed in. All is pretty much lost. Time is up. Defeat is inevitable.
Ramsey had bullied John's army into submission. He could have ended it quicker. But he wanted the enemy to suffer.
Ramsey, for all his intelligence, his biggest weakness is also his strength. He knows how to make people suffer and he enjoys it.
With Ramsey exposed, and his army ready to deal the final blows, Sansa appears with Littlefinger and an army.
Ramsey was completely taken by surprise. John played into his hands completely. Sansa didn't. Remember, she knows Ramsey and how he works. Sansa played out her strategy brilliantly.
So, in my view, what was Sansas strategy? At a high level I think:
- Call on Littlefinger for support
- She knew they were coming well before they showed up
- If Littlefinger and his army had stood side by side with John at the start of the battle, it would have been a 'fairer' fight.
- Sansa wanted have the best chance of winning
- She accepted that her brother(s) could/would die
- She also knew that many others would die. She knew how John would react. She knew, for the most part how the battle played out.
I am saying, based on what I have seen, that Sansa won the battle with the best strategy.
She did not make the mistakes that her father and brothers had done before. She accepted that Rickon was dead. She knew there was little she or John could do to change that.
So she took advantage of Ramsey whole he was playing his game. When the battle was almost won, Sansa came in to change the rules of the battle.
This is why, for one of the few times in Game of Thrones, the 'good guys' won.
One final point,Sansa's end for Ramsey. Some will say 'deserved', but is that the Stark way? Starks have honour. They do things the 'right' way.
Sansa fed him to dogs and watched.
This is another reason why I believe Sansa is becoming a key player in the Game of Thrones. The good guys don't win. That is what everything in the show has told us.
So for the Starks, and more so Sansa to win, she had to change the rules. She put her emotions and honour to one side, so she could win back her home.
tl, dr
Sansa knew how John would react. She planned for Little finger and army to arrive later. This gave them best chance of winning.
She accepted there would be losses, including putting her brothers at risk.
Had she gone the true 'Stark' way, she knew they would lose everything.
Now she has her home back.
