What was the main reason the North thought it would win the Civil War? What was the main reason the South thought it would win the Civil War?

The north believed they would win because of their railroads and numbers, along with the fact that they were better established as a government. The south believed they would

win because they had the home field advantage, and were fighting for their way of life, along with the fact that they had better generals. The battle of bull run also over inflated the confidence of the south.
