The civil war was fought between the northern and southern states from 1861 to 1865 over the issue of slavery. The southern states wanted to expand and protect slavery, while the northern states wanted to limit its expansion. One of the last major battles of the civil war took place in Columbus, Georgia in 1865, where Union forces led by Major General James Harrison Wilson defeated Confederate forces led by Major General Howell Cobb. The outcome of the civil war was the defeat of the southern states and the abolition of slavery.
