Why did people believe that the civil war would not last very long? 40 points+brainliest

The American Civil War was far longer and more destructive than virtually anyone expected. At the outset of the war, many eager volunteers signed 90-day papers, evidence of the widespread belief that the war would be brief and nearly bloodless. Instead, the struggle stretched nearly four full years.

Explanation:

Many people thought it would be a shorter conflict.

Explanation: One reason why the Civil War lasted four years is that the South had better military generals than the North had. Many of the military schools were located in the South, and the generals tended to fight on the side that their home state had supported
