According to Nafziger's book on Dresden, Ledru's division had two batteries of Westphalian artillery (in addition to a French battery), each with 6 6lb pieces. According to Nafziger's book on Russian in 1812, there were two 6 lb batteries with 8th corps, each of those had 6 6lb pieces and two howitzers. Did the Westphalians change the constitution of their artillery batteries after 1812, or were they just making due with what they had?

Thanks,
