EXPLANATIONS BELOW
Concept note-1: -Warren County, MS | May 18-Jul 4, 1863. Vicksburg’s strategic location on the Mississippi River made it a critical win for both the Union and the Confederacy. The Confederate surrender there ensured Union control of the Mississippi River and cleaved the South in two.
Concept note-2: -During the next two months, Union forces rained cannon fire down upon Vicksburg. The Confederates suffered in the unbearable summer heat and were forced to ration their few remaining supplies. Quickly, Union troops dug tunnels under the fortifications and detonated explosives that devastated the city.
