What were the strengths and weakness of the union?

Answer 1

During the American Civil War, the Union side enjoyed the advantages of superior numbers of people and of soldiers, vastly greater industrial resources and arms, a well-trained and active navy, and a fully organized and operational political administration, among other strengths. Its primary weakness was its need to invade the South, defeat Southern armies, and occupy Southern strong-points as the basis for forcing the South's surrender.
