Oh, I didn't take it negatively. I just wondered what you defined as minimalist. I'll keep the elements to a minimum but I'll put in every single tree (they're in the ref. map I'm using). I love making trees.
The arty will be 48 pounder breach loaded cannons with rifled barrels. Made by Åkers Styckebruk in 1863. I think there's 120 or so, but only about 20 on the walls, most of them are on the second floor of the land front and 30 or so are in the bastions in the moat. The land front was used as barracks as well as the main defense. It was the first pemanent indoor quarter for soldiers in sweden and was critizised for making the soldiers soft with heating and running water. The top floor was officers aparments and some of them had a big cannon in the living room (the officer got a pay bonus for maintenance of the cannon).
The southern wall of the land front is 2-2.5m thick limestone while the peace side (north side) is much thinner.
The western bastion was a water cistern as well as a gun emplacement.
