Citizens from Washington came out to watch the battle.

Explanation:

In the early days of the beginning of the civil war, the citizens of the north were not very terrified of the idea of the war.As the entire war place took place in small battles fought at different places, the intensity of the war was not felt to the extent that it should have otherwise been felt. Moreover, the northerners had this notion in their mind that they were fighting for a good cause and they had no reason to be afraid of anything.
