Answer :
All the events listed were important to the Union war effort but perhaps the most important were:
- The Emancipation Proclamation
- Sherman's Atlanta campaign
The Emancipation Proclamation was very important for several reasons such as:
- It encouraged Blacks to join the Union army in droves
- It made the war about slavery which meant that the European nations could not support the Confederacy as they were anti-slavery
Sherman's Atlanta campaign was also hugely important because General Sherman's capture of Atlanta directly led to Abraham Lincoln being reelected and continuing the war until the Confederacy was defeated.
In conclusion, the Emancipation Proclamation and Sherman's actions in Atlanta were very important.
