Answer and Explanation:
As you already know, the Civil War was an armed conflict between the northern states (which formed the union army) and the southern states (which formed the confederate army). The aim of this war was to determine whether southern states could separate themselves from the United States and form an independent country and whether slavery should be banned across the country.
The Confederate Army had the advantages of easy access to supplies, since it was formed by the states that promoted all the agricultural production in the country. In addition, the Confederate army had a good banking system, which facilitated financing for the war.
However, the Union army had a larger number of soldiers and a stronger economy, in addition to having a large production of weapons and ammunition. These advantages gave the union victory, but in addition, the lack of foreign support for the Confederate army and the blocking of southern supplies that the union made, allowed them to win.
