As the Civil War ended, Mrs. Lincoln expected to continue as the First Lady of a nation at peace. President Lincoln awoke on the morning of April 14, 1865, in a pleasant mood. Robert E. Lee had surrendered several days before to Ulysses Grant, and now the President was awaiting word from North Carolina on the surrender of Joseph E. Johnston. The morning papers carried the announcement that the President and his wife would be attending the theater that evening. At one point, Mary developed a headache and was inclined to stay home, but Lincoln told her he must attend because newspapers had announced that he would. She sat with her husband watching the comic play "Our American Cousin" at Ford's Theatre. During the third act, the President and Mrs. Lincoln drew closer together, holding hands while enjoying the play. Mary whispered to her husband, who was holding her hand, "What will Miss Harris think of my hanging on to you so?" The president smiled and replied, "She won't think anything about it". That was the last conversation the Lincolns ever had. Five minutes later, at about 10:15 pm, President Lincoln was shot by John Wilkes Booth. She was holding Abraham's hand when Booth's bullet struck the back of his head. Mrs. Lincoln accompanied her mortally wounded husband across the street to the Petersen House, where he was taken to a back bedroom and laid crosswise on the bed there, where Lincoln's Cabinet was summoned, except William Seward, who had been seriously attacked by Lewis Powell, just as Booth was about to carry out his assassination at Ford's Theater, several minutes earlier. Their oldest son, Robert, sat with Lincoln throughout the night and to the following morning– Saturday, April 15, 1865. At one point, Secretary of War Edwin M. Stanton ordered Mary from the room as she was so unhinged with grief.
