The Assassination was planned in a bar and the reason they wanted to do this is so that they could get revenge on the North. They were going to try and kill Lincoln, Seward, Johnson, and Ulysses S. Grant
The actual assination occured in a Theatre by Booth while the others should have been assisnating the people they were adssigned to.
The only successful assassination was the one where Booth killed Lincoln. He ran away on his horse to try and escape but was eventually found anyway along ith his team.
