The Civil War of the 1860s fought between the North (Union) and the South (Confederates). Many expected the South to win the war because it had the military advantage as they knew the terrain (landscape) better than the North and battled for their land. The South more men qualified as officers and soldiers. Majority of the famous Generals and Commanders in America were from the Southern region including; Robert E. Lee, Nathan Bedford Forrest, James Longstreet, Stonewall Jackson and others. The Confederate officers recognised by their ambitious nature and individualistic. They followed the rules of honour and personal pride, which help them to fight together for the cause.
I believe the answer is the Southern Region. Despite the advantage in numbers, the northern forces still has several factors that could endanger the southern Forces, such as the north has more modern factories to produce weapon and about a third of the southern population were slaves that want the north to win.
Because history gives us the tools to analyze and explain problems in the past, it positions us to see patterns that might otherwise be invisible in the present – thus providing a crucial perspective for understanding (and solving!) current and future problems.
