What if confederates took Vevay，Aurora，Rose and Middletown. Union still held Cincinnati

If the Confederates were able to take Vevay, Aurora, Rose, and Middletown, they would have gained control of important transportation and communication routes in the region. However, the Union still held Cincinnati, which was a crucial industrial and economic hub.

The Confederates would have had to maintain their hold on the captured towns and defend against potential Union counterattacks. They would also have to deal with the challenge of supplying their troops and civilians in the occupied areas.

The Union, on the other hand, would have to focus on securing their hold on Cincinnati and reinforcing their defenses in the surrounding areas. They would also have to consider launching an offensive to retake the captured towns.

Overall, the capture of Vevay, Aurora, Rose, and Middletown would have been a significant strategic victory for the Confederates, but the Union's control of Cincinnati would have made it difficult for the Confederates to expand their gains and ultimately win the war.
