"According to all human calculations we should have saved Atlanta had the officers and men of the army done what was expected of them."
I have always found this to be an utterly disgraceful statement. Hood is basically trying to assert that Atlanta fell because his men were not brave enough. There were no braver men on Earth than the soldiers of the Army of Tennessee.
I've always contrasted this statement with that of Robert E. Lee after Pickett's Charge, when he rode among the men and told them that it was all his fault.
This certainly is not the same Sam Hood who was greeted with tumultuous cheers by his men when he appeared upon the platform going to Chickamauga despite his shattered arm... only the stress and laudanum excuse such a ridiculous statement.
