He does not say what he based this on.

In an earlier posting from John Wladis
> Charrier says that Bernadotte failed to answer Davout’s calls for help. He identifies two such messages: The first delivered by Gen Romeuf around 10 am to Bernadotte near Camberg (citing Segur, Souvenirs d’un aide de camp de Napoleon at 306); the second by Trobriand, who encountered Bernadotte about 4:07 at Apolda. Trobriand apparently wrote a letter to Davout's daughter decades later describing his interaction that day with Bernadotte. Charrier doesn’t believe that Trobriand’s letter was a hoax. He found a report of Trobriand’s mission not in Trobriand’s handwriting at SHAT. <

I've just been looking at the Lettres de marechal Davout (on my way to the Dupont folder) which includes the report from Trobriand. Trobriand claimed to have been sent from the battlefield at 3.30pm and to have found Bernadotte at 4.07pm. He told Bernadotte that the enemy was in full retreat and that Davout was inviting him to 'assist in the pursuit of his success.' (Possibly a bad choice of words) Bernadotte, after asking who had been killed, said "Retournez pres de votre marechal et dits-lui que je suis la et qu'il soit sans crainte. Partez."
Trobriand found Bernadotte's manner offensive.

I wonder if this is the origin of the story that Bernadotte refused to assist? I don't know whether he did actually do anything useful at this point but it was clearly to late to influence the outcome of the battle.

The other reference to Romeuf having been sent earlier is stated as having been based on Segur's memoirs and so should not be accepted without corroboration.
