Do you have a limber for that beast?  I can find load of cannon videos but only one that shows a cannon under horse power being unlimbered.  What would be cool to watch is and entire battery being pulled forward, unlimbered and put through the firing order.

Being a civil war student since reading a 1965 national geographic about Five Forks I tried to envision CW artillery being shot while under fire like at the Peach Orchard at Gettysburg.  Had to be hell.
