Further, I have done quite a bit of research on the artillery arms of the period and have
quoted material from the best work on the Russians army in English.
Indeed I would also be interested to know what those sources are?
So far those quoted sources seemingly are not suitable to gain an indepth knowledge about Russian artillery.
Moreover - in case one wants to discuss Russian artillery seriously one whould have to consult many Russian sources about this topic as well, otherwhise one would gain only a superifical knowledge.
