Ulysses S. Grant,
Personal Memoirs of U. S. Grant…
“ Suffice it to say, the close of the siege of Vicksburg found us with an army unsurpassed, in proportion to its numbers, taken as a whole of officers and men. A military education was acquired which no other school could have given. Men who thought a company was quite enough for them to command properly at the beginning, would have made good regimental or brigade commanders; most of the brigade commanders were equal to the command of a division, and one, Ransom, would have been equal to the command of a corps at least. Logan and Crocker ended the campaign fitted to command independent armies. ”
