Dear H-K, with apologies for much delayed response:
* Do not believe Wrede's report was ever printed anywhere. Located in the Kriegsabteilung of the Bavarian Staatsarchiv, B445.
* Read through all of the available Austrian reporting ("Relationen") in preparing vol. III of "Thunder." There are interesting impressions of MacD's attack, but nothing on the formation used and, of course, no details on French order of battle.
