i had a single full native infantry in fort Oswego and it was assaulted by a force much larger. I didn't expect to win, but nonetheless, i was expecting the fort defenses to do something.

Enemy infantry advanced directly in front of the defending unit to well within musket shot, turned, exposed it's flank, stopped still for a moment, and proceeded to walk around the fort to climb up the side, raked by heavy and small arms fire all the while.

With the fort cannons and defending muskets blazing away at the hapless assaulters at point blank range, i was a little surprised to see that the total enemy casualties before they started to scale the walls were two.

There is little doubt in my mind that the defenders would have inflicted more damage if they didn't use the fortifications at all.

Is this a typical feature of fort defenses?
