Written nearly six years before Indiana would be admitted into the United States, Col. James Simrall gives thorough details of the exploration that was made in the area of what would become Indiana around the Mississinewa River area. He detailed greatly what he saw, and took note of significant Indian tribes that were in the area. This would be significant in that the new government would have to take into account the thousands of Native Americans that populated the area, and how the people would be handled, treated, and dealt with when becoming a state.
