Dr. T. S. Verdi, Secretary William Seward’s doctor, described what he saw when he arrived at Seward’s mansion after the attempted assassination:

“I had left Mr. Seward about nine o’clock in the evening, very comfortable, in his room, and when I saw him next he was in bed, covered with blood, with blood all around him, blood under his bed, and blood on the handles of the door.”
