Marines vindicated

[L Verge]

Grant had issued the invitation at the suggestion of his wife, Julia, who had been struck by constant newspaper report of "the exhausted appearance of the President." Grant worried at first about the propriety of issuing an invitation when the president could visit without waiting "to be asked," but on March 20, he wrote a note to Lincoln: "Can you not visit City Point for a day or two? I would like very much to see you and I think the rest would do you good."

I wonder if Julia meant for the invitation to include Mary, too (as she did come).

Interesting question because the General's invitation certainly seems to be in the singular form.
