The Riflemen Of The Ohio [EPUB ebook] 

The story is about a group of men, led by Adam Colfax, who are on a journey up the Ohio River to deliver supplies to the colonists in Pittsburgh. The voyage, which starts from the Mississippi River, is dangerous as they have to navigate through the thick forests haunted by warlike tribes. Despite the danger, the men remain steadfast and resolute in their mission. Henry Ware, a young boy in the group, is particularly alert and vigilant as he scans the surroundings for any signs of danger. The journey is long, but the men remain upbeat and are comforted by the majesty of the wilderness around them. They are driven by a strong sense of purpose, and even though they face many challenges, they are determined to complete their mission.
