Explanation:

In the narration of events that happened on that night, the author expresses his thoughts vividly on the present state of the President and that of his Secretary of State.

In the words of the author, "the pistol ball entered the back of the President's head. The wound is mortal. The President has been insensible ever since it was inflicted, and is now dying".

A mortal wound is one that results to death. The author also said that the President is dying.
