Although American civil war remains one of the deadliest wars in American history, it failed to accomplish the initial aim of liberating the south and enforcing civil liberty. According to Hugh (1999) the war is estimated to have cost more than 620,000 lives among the fighting soldiers while there are an undetermined number of civilians who lost their life in the course of the war. The war was caused by differences between the southern states and the Northern federal government specifically when the Union led by President Lincoln declared the abolition of slave. The ascendancy of Lincoln to president led seven states in the south to declare their secession and consequently formed the confederate states of America. This was considered as rebellion by the US federal government triggering the civil war. However the issue of slavery remained central to the difference between the South and the North.
