Typically the Russians in 1812 and 1813 had three batteries with each intantry division, two field batteries and one position battery, although in some divisions the position battery was not always present, particularly in the 1813 armies.
Each battery comprised of eight field guns and four howitzers. In the field batteries the guns and howitzers were 6lb and 10lb pieces respectively, while the position batteries were 12lb and 20 lb pieces.
In my rules a battery is usually represented by a single gun model and its crew, but in the case of the Russians, since their batties are substantially bigger than others, I have made them two models, one field gun and one howitzer.
The position battery and the horse artillery battery, the two items required to finish the artillery contingent, will be ordered in the next month or two.
