"It was the darkest day of my life," Grant told newsman John Russell Young. "I did not know what it meant. Her was the Rebellion put down in the field, and starting up in the gutters. We had fought it as a war, now we had to fight it as assassination."
Recall, there was an attempt on Grant's life as well that night, but the Grants' railroad car door when stopped at Havre de Grace (where I've been -- Maryland), was locked, preventing the assassin getting to Grant. The assassin wrote an unsigned note later to Grant, thanking God that he'd been prevented from attempting to kill him.

The Rebellion continues to this day, by many, many other means, but particularly via those hatched in the gutters of mind and media.
