What was the biggest threat of traveling west in the manner shown in the illustration

The illustration depicts a group of pioneers traveling west in covered wagons during the era of westward expansion in the United States. Based on this context, one of the biggest threats they faced was the risk of encountering hostile Native American tribes. Conflict with Native Americans was a significant challenge for westward travelers, as they often faced attacks, raids, and ambushes. Native American tribes defended their lands, cultures, and resources from encroachment by the settlers and the federal government. These confrontations, known as the Indian Wars, resulted in casualties on both sides and brought about significant hardships for the pioneers traveling westward.
