Similar to the Vauban style fortifications of Lille, Tournai, Courtrai, Mons etc.? I'm obsessed with those styles of fortifications and haven't found a movie or even a good documentary that depicts what an attack would've looked like..
Well, I haven't seen anything that does but for lack of a better word, for good reason.
Forts of the 17th century, such as the Vauban fortresses, served two purposes; they served as garrisons and storehouses or they acted as a barrier which an invader had to take before marching in. These fortresses were expected to last eighty days by Vauban's expectations. As a result, a 17th century siege would have been a long and boring affair for both the attacker and the possible viewer of a film about it. Battles are more dashing because they have movement, sieges rarely have movement.
