Game of Thrones, Season 4

Jon:
That's the last of the oil, Ser Alliser.

Alliser Thorne:
A hundred thousand, you say?

Jon:
Yes, sir.

Alliser Thorne:
You can say it if you like. We should have sealed the tunnel while we had the chance, like you suggested.

Jon:
It was a difficult decision either way, sir.

Alliser Thorne:
Do you know what leadership means, Lord Snow? It means that the person in charge gets second guessed by every clever little twat with a mouth. But if he starts second guessing himself, that's the end. For him, for the clever little twats, for everyone. This is not the end. Not for us. Not if you lot do your duty for however long it takes to beat them back. And then you get to go on hating me, and I get to go on wishing your Wildling whore had finished the job.
