I really enjoyed the latest podcast on this subject; where the panel contested a selection between Austerlitz ("safe choice?"), Berezina ("brave choice?"), Marengo ("provocative choice?") and Rivoli ("clever choice?")
My own candidates would have been ones which exemplified Napoleon's use of initiative and momentum, with armies small and compact enough to follow his own intentions. At the risk of cheating over the definition, how about the Champaubert / Montmirail action of February 1814 leading to further success at Chateau-Thierry and Vauchamps?
