Napoleon was originally an artillery commander. That's where he got his start in the military. And it was his brilliant use of heavy guns that won many battles for the French. Soon, you'll be able to utilize these heavy guns for your own conquests as new French Artillery pieces are coming for Black Powder.
From the announcement:
French Horse artillery batteries of the Napoleonic era had six guns, four 6-pounder cannon and two 5.5 inch howitzers. The Howitzer was the go-to gun ideally used break open formations and fortified locations prior to and in support of an attack. Horse artillery batteries had approximately eighty gunners and a similar number of drivers, all being mounted.
