Quote context

[...]

- Sargento, ¡condúzcalos ustedes!- De frente. Marchen!

- Federales are very efficient.

- Yeah. Bandidos, eh?

- Yeah. Seems between them they had a diamond ring, pearl earrings, quite a lot of money, and a railway ticket with the date of the aguas caliente train robbery on it.

- They've been here several days drinking and shooting off their cannons. The villagers are afraid to stick their noses out of their huts.

- Where are they taking them now?

- The cemetery.

- Oh.

- Buenos dias, amigo.

- Buenos dias, mercante.

- ¿Qué va a llevar ahora?

- Un castol de maiz, harina, 12 kilos, azucar, 12 kilos.

- You know, the federales don't operate in our American way. They aren't fingerprint experts, that is. They can follow any trail. Against them, no hideout's any use. They know all the tricks of the bandits.

- Yep, you can bet your sweet soul they'll trace down every last one of that group that attacked the train.

- It'll take time... months maybe... But they'll do it.

- Frijoles, 10 kilos. Petroleo, 18 litros.
