The sternwheeler Bertrand struck the submerged tree trunk and struggled to reach the shore as it was sinking. The Burleighs escaped, then decided to complete their journey to Yankton in the Dakota Territory overland. They hired guides to get them there, not knowing that the guides' plans were maliciously different. There would be deaths on the plains of Nebraska Territory.
