Step-by-step explanation:
Was prepared for a long war, is the right answer.
The first significant battle of the American Civil War was the First Battle of Bull Run. This battle was fought on 21 July 1861, in Virginia at Prince William County. The Union's troops were detained in placing themselves, conceding Confederate force's support time to reach by railroad. Each group had about 18,000 inadequately prepared and crudely commanded crowds in their first encounter. Though Confederate forces won the battle, the battle expressed that neither side was prepared for a long war.
