Pantactic,
[Mods, I do hope you will excuse what is likely to be a cross post, I did include substantially the same apology to Pantastic, in the Gurderian / Stonewall Jackson thread.]
Here is a link to what Wikipedia has to say.
It appears that I principally remembered the Von Moltke quote. The Wikipedia article strongly suggests the quote is spurious.
If you are still following the Gurderian / Stonewall Jackson thread. I was wrong about the extent the Prussians / Imperial Germany studied the U.S. Civil War. I apologize for my intransigence in that regard.
Zuer-coli.
