It would seem that The Duty Letter, repudiated by both the alleged writer and the addressee, is so discredited, that its spuriousness would be conceded, "without hope of rescue." But this is by no means the case; and we must now examine several theories (or suppositions) upon which its substantial genuineness is by some still maintained. These theories I shall call (1) The Wrong Date Theory; (2) The Editorial Emendation Theory, and (3) The Compilation Theory. Let us examine them in their order.

He could not, therefore, at that time, have written the first two sentences.
But may not "April 5, 1852," it is asked by those who espouse The Wrong Date Theory, be an error of General Lee, or of the copyist, or of the printer? Should not the date be changed to some other time which will fit the facts? Is it not more reasonable, they ask, that there should be an error in the date of The Duty Letter, than that the first two sentences, assuming the date to be correct, should contain so glaring an anachronism, so egregious a blunder?
