Again, do you have a citatino for Napoleon's purpose and intent.
It should be noted that only two of the planned An XI pieces of ordnance were put into production in any quantity: the 6-pounder and the new howitzer. The ancillary vehicles never replaced the Gribeauval antecedents and Gribeauval 8-pounders and howitzers were with the Grande Armee through the Campaign of 1809. Davout's III Corps was equipped with them. The numbers are listed in the first volume of Saski. What AN XI actually did in practice was supplement Gribeauval and did not entirely replace it. There wasn't the time and assests to get it done. Further, there was so much useful captured ordnance that was employed with the Grande Armee that in many instances it wasn't needed. Lastly, many artillerymen considered the Gribeauval 8-pounder to be a better field piece than the new 6-pounder and didn't want to give up the older piece.
