The heroes realize from the increased volume of gunfire that they're suddenly facing twice as many foes compared to a moment before. The bad guys talk strategy:
“You can only glimpse their refuge from that side, but you’d be out in the open.”
“It's not a problem. We'll have covering fire. How are they equipped?”
“Three rifles: one each, plus the one taken from Carlos. The old man also has a pistol. No heavy weapons.”
“We could attack from the position indicated by Carlos, while Fernando covers us. What do you think, Lope?”
“All right. Let's go!”
“Fernando, you cover us! The others, with me!”
“Yes, chief!”
“Blood of Judas! The volume of fire has decreased, but it's almost impossible to stick your head out. Looks like there's only one shooter left up there, and he's a damn good one.”
“They're preparing an attack. They will try to outflank us while that sniper prevents us from adequately defending ourselves.”
“Then we need to get him out of the way.”
