What was the north's response to secession? how did both sides try to compromise?

The north reacted by punishing the south for seceding. They stop supplying them and set up naval blockades to keep them from trading with other countries. They both tried to compromise by making negotiations about slavery and other topics.

They got mad with the south, and became angry and punished them.
