What was demonstrated by the First Battle of Bull Run?

Question

1. that the North would win
2. that the South was better trained than the North
3. that African American soldiers would be useful to the Union army
4. that the war would be long

Answer 1

The First Battle of Bull Run, fought on July 21, 1861, demonstrated primarily that the war would be long and difficult. While some Confederate troops showed better organization and morale, the battle itself did not conclusively prove that the South was better trained than the North, nor did it provide evidence that African American soldiers would be effective. Additionally, it did not establish that the North would win the war early in the conflict. Therefore, the most accurate conclusion from the First Battle of Bull Run is:

4. that the war would be long.
