While Napoleon's Bulletins were definitely not intended as history, they most certainly did contain factual information in the narrative. To completely ignore what was stated in the Bulletins would be to ignore some valuable information. Of course, it takes some work to figure out which was which at times. It would be the same to ignore, for example, Marbot's memoirs because they contain much 'remembering with advantages.' There is still excellent information contained, such as Marbot's compliments to Ameil (an officer whom he did not like) and his narrative of the fighting and aftermath at Borisov in 1812 when he was a regimental commander.
