Wasn't Hohenlinden an accidental meeting engagement where Moreau's somewhat haphazard and careless dispositions were made up for by the combat leadership of such subordinates as Ney, Richepanse, Decaen,
and Grouchy? I'm not sure if Moreau was even in control of the battle as it was in actuality fought by his subordinates with Moreau assuming the role of spectator?
Additionally, wasn't Moreau surprised by the advancing Austrians. He didn't have any plan of maneuver and didn't employ any effective reconnaissance. The surprise Austrian advance accordingly forced him to retire.
Lastly, it should be noted that Napoleon directed the three campaigns going on (Germany, Italy, and Switzerland) from Paris, issuing his commanders 'general, mission-type orders' and forwarding all types of support to them if and when it became available. Seems to me that to ascribe the French victory in the winter campaign of November 1800-February 1801 solely to Moreau is mistaken, selling both MacDonald and the Army of Italy short, as they too contributed to the win.
