Asking him to collaborate on a history of the war, to be written under his general direction ("Considerable capital has been collected for the publication, well after the cessation of hostilities, of a great history of the war. ... There is no one whose collaboration I should desire more than yours, and I would like to see you upon the matter. There is ample time. To a period some months after the termination of hostilities (as we hope) all energies will be confined to sifting and arranging material, but I would like to bespeak you for a particular part of the work, and to hear your views.")
