Yup, that's the one, the 12 pounder bronze howitzer--"the Napoleon," the workhorse of both armies. Don't let the name confuse you, we Yanks have a tendency to name our military equipment after dead generals--re: Abrams, Bradley, Patton, Pershing, Sherman, Stuart, Lee, etc. I believe the Napoleon was so named because it designed by or for Napoleon III's army, however, like alot of things, I could be wrong.
