Sách nói: Personal Memoirs of U. S. Grant

"In preparing these volumes for the public, I have entered upon the task with the sincere desire to avoid doing injustice to any one, whether on the National or Confederate side, other than the unavoidable injustice of not making mention often where special mention is due. There must be many errors of omission in this work, because the subject is too large to be treated of in two volumes in such way as to do justice to all the officers and men engaged. There were thousands of instances, during the rebellion, of individual, company, regimental and brigade deeds of heroism which deserve special mention and are not here alluded to. The troops engaged in them will have to look to the detailed reports of their individual commanders for the full history of those deeds".
