Three natives in dark green clothing, to camoflauge themselves, silently stalked through the forest.

But up on the ridge were Gilbert, his native guide, and a mercenary, carefully keeping watch. They believed these were some of the men who attacked the previous expedition.
"Don't make a sound," Gilbert warned, carefully keeping watch.

"There!" Gilbert said, elbowing his native guide. "Let the others pass, they'll lead us to their camp. Take Out ol' pegleg though."

FWWP! The native but a dart into his blow gun and shot. They heard the peglegged enemy fall to the ground, seeing his blood spill out.
"Good," Gilbert said. "Signal the others, I think we found their hideout."
