in 3 sentences

The Union faced the challenge of financing the war through increased taxes and borrowing, while the Confederacy struggled with funding due to its lack of a centralized banking system and limited resources. As the war dragged on and casualties mounted, public opinion shifted from initial support for the war to growing dissatisfaction with its costs and toll on both the economy and society. This led to increased calls for peace and calls for an end to the conflict from both sides.
