Berthier (whose fortè was staff work) proved to be an insufficient field commander, a characteristic made worse by the fact that several messages from Paris were being delayed and misinterpreted when they finally arrived at headquarters.
Berthier (kelle põhitöö oli staabitöö) osutus mitte küllalt heaks välikomandöriks, iseloomujoont raskendas asjaolu, et mitmed teated Pariisist hilinesid ja mõisteti valesti, kui need lõpuks peakorterisse saabusid.
