I forget his name but, we had a speaker whose GR GR grandfather fought in the Battle of the Ravine. As he was severely wounded, his involvement was well documented. His grandfather was a German Immigrant, a skilled stonecutter. He suggested many of the immigrants fought for the Union because they came to America to better their living conditions. Once here, they were forced to compete against 'slave labor' used in much of the industry. He also noted, many came to America on ships used to transport cargo, not humans because they could not afford passage otherwise. As the ships returned to America to pick up cotton, cheap fares were offered by the shipping companies. As the Mississippi River served as a primary transportation route and St Louis the Gateway to the West, it makes since many chose the Midwest opposed to New York given the economic conditions of the times.
