This is a German-crewed culverin (or bombard) mounted on a adjustable split-tail carriage. In modern terms this is not a particularly large gun, but to those living in the 16th century this would have been quite an impressive piece of artillery. (With it being near as much a danger to its crew as it would be to their intended targets.)
The figures are from Redoubt Enterprises and while they are a bit ill-formed and perhaps a tad lumpish, I find they have a certain charm and posses a wonderful dynamism, especially in how their various poses convey a sense of movement. These fellows really convey the idea of them frantically trying to realign their gun while in the midst of combat.
I tried to match the groundwork to the rest of my bases, which are all autumnal, so a wide assortment of brown foliage, late blooms and a generous carpet of fallen leaves are in appearance. If it weren't for the big freakin' gun and its boorish crew of beer-swilling Landsknechts, perhaps it would be a nice place for a quiet repast with a bottle of Chianti, a loaf of fresh bread and a plate of prosciutto. Ah, bellissimo!
