The capture of vicksburg in 1863 contributed to the course of the civil war by preventing the union from gaining access to the west. allowing the confederacy to remain strong and unified. maintaining confederate control of the mississippi river. raising union morale and damaging confederate morale.

raising Union morale and damaging Confederate morale.

the capture of Vicksburg split the confederacy in two, and made it harder for the confederates to group together. Instead, they were split into seperate armies. Also, the capture of Vicksburg damaged Confederate morale because it was thought to be inpregnable

hope this helps
