In chapters 12 and 13, Huck and Jim discover a damaged steamboat that is slowly sinking. Curious, Huck asks Jim to tether their raft to the boat. When Huck climbs aboard, he sees three robbers: one tied up, one wanting to kill the tied-up robber, and the third suggesting they leave the man there to sink with the steamboat.
When Huck rejoins Jim, he is informed that their raft has untied and drifted down the river due to the storm. Huck and Jim then decide to look for the robbers' skiff. They find it, jump inside, and cut the rope to escape before the robbers make their way to it. By doing so, they not only escape but make sure the robbers won't get away.
Huck and Jim speedily float downstream in the skiff. Moments later, they find their raft and leave the skiff behind. However, Huck feels guilty leaving the robbers in the sinking boat, and he decides to inform a nearby ferry night-watchman about the steamboat.
