Uh-huh. You seem to be attacking things I did not say and proving that what I did say did happen.Yes, and in this case you're relying on a single claim, by the man himself.
No-one doubts Senarmont lined up 30 guns and that that gun-line fired on the Russian infantry. What is fantastical is Senarmont's claims that he advanced his guns like they were tanks, without infantry or cavalry support. Indeed, it begs the question if that what he did, and it was effective, why was it never replicated? It is claimed that the 30 guns fired canister continuously for 25 minutes, but they expended expended 368 canister rounds (1 round per 2 minutes per gun) in the whole battle, so this is obvious BS.
The truth is more prosaic; the Russians attacked DuPont's division, which Senarmont's guns were deployed in front of. They then advanced with the own infantry and cavalry as they advanced, exactly as per the manual. The Russian artillery could not return fire, because their own troops (who were advancing) block their shoot.
The hyperbolic claims of "artillery as an independent arm" are nonsense.
