American Civil War

A war over secession and the continuation of slavery; organised resistance ended in May 1865.

This west-to-east line links the western and eastern theatres in one simplified picture of changing control. The war involved separate armies, river corridors, coastal occupations and contested rear areas, not a single continuous front. The Mississippi curve of 1863 and Georgia curve of 1864 stand for routes and local footholds, not occupation of all adjacent land. From 1862 New Orleans is a separate Union foothold, graphically connected only in 1863. Texas, Florida, the blockade and later surrenders are not fully represented. Closing edges and transitions are schematic.
