'For Bernadotte at Auerstadt, I suggest checking another thread on this forum where this issues has been discussed in detail. This issue is more complicated than Bernadotte's refusal to help Davout...'
Alex,
I hate to disagree with you, but the issue with Bernadotte in 1806 is as simple as his refusal to support Davout. That's what happened. Much has been written about it on the threads below, but the simple fact is that Bernadotte failed to support Davout and he failed to get into action on 14 October.
Sincerely,
K
