The answer is: following a bloody battle.
After the Battle of Gettysburg in 1863, which was essential to the American Civil War, President Abraham Lincoln delivered a speech to encourage people to take measures and help create a better nation, joining north and south, in honor of those who perished in the armed conflict.
The ferocious Battle of Gettysburg concluded with 10,000 soldiers dead, 30,000 injured and 10,000 abducted or missing.
