Lincoln wrote a letter to General James Henry Van Alen of New York, in which he said: "I thank you for the assurance you give me that I shall be supported by conservative men like yourself, in the efforts I may make to restore the Union, so as to make it, to use your language, a Union of hearts and hands as well as of States."
The cabinet met at 11:00 a.m. that morning.
