Quote context

[...]

- Up here is the Sabine River. Somewhere around here, Sam Houston is trying to organize an army. And right in between is the Alamo.

- Santa Anna can't go around and leave a fort along his lines of communication. He must reduce the Alamo by storm.

- Every minute of time we buy for Sam Houston is another precious minute in the life of Texas.

- And, Crockett, nobody is ever going to say that William Barrett Travis did not buy every minute possible.

- Makes sense. Why didn't you tell Bowie that?

- Because a commander does not have to explain his every decision.

- You explained to me.

- I have great respect for you, Crockett, but I have none for that knife-fighting adventurer.

- I figured any fella that shouldered a gun was deserving of respect. But then, I'm not a real soldier. I never fought anybody but Injuns. Less'n you count the British.

- I must ask you to forgive my rudeness earlier on to you.

- I'm an easy forgiver... at times.
