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

If the Confederates were able to take Vevay, Alexandria, Blanchester, Aurora, Rose, and Middletown, it would have been a significant blow to the Union's hold on the region. These towns were strategically important because they were located along the Ohio River and provided access to important trade routes and resources.

However, the Union's hold on Cincinnati would have still been a major obstacle for the Confederates. Cincinnati was one of the largest cities in the region and was a key transportation hub, making it an important target for both sides. If the Confederates were unable to take Cincinnati, they would have been cut off from crucial supply lines and reinforcements, which could have weakened their position.

In addition, the Union would likely have responded aggressively to the Confederate advance, launching counterattacks and attempting to retake the lost towns. This could have led to a prolonged and bloody conflict in the region, with both sides fighting for control of critical territory.

Overall, while the loss of these towns would have been a setback for the Union, their hold on Cincinnati would have given them a significant advantage in the conflict.
