The main advantage that the South had at the beginning of the war was its large army and well-trained generals.

However, the North's advantages were finally just greater. The South relied on agriculture, which was rendered unviable during the war. Moreover, it had a much smaller population, and its workforce was destroyed after emancipation. All of these put the Confederacy in a particularly difficult position.
