Why might a recent immigrant fight for union/confederacy?

They saw it as a fight against slavery and a fight for freedom and democracy.

Explanation:

Of every 4 union soldiers, one of these 4 were said to be an immigrant. This group made up a significant percentage of the united states army during the confederate war. They gave the United States a great advantage that helped them to win the war.

This question requires us to state the reason why these foreigners enlisted to fight. The answer is that most enlisted to fight for democracy and freedom from slavery. Some of these immigrants were Germans who had experienced slavery from their government. They saw this as a revolution against aristocracy and slavery.

c) they were beaten and fired from their jobs.
