"The morning begun like others these past two weeks of siege. Load roaring of continuous shelling with the occasional tremors as a shell struck the observation cupola of the fort. Nothing too bad we thought, the fort will hold... their 90mm's can't make a dent in our walls. In an hour the Empire would show us otherwise. No more than three of us made it out of the ruins after they used Fort Krajow as target practice for their newest piece: a 320mm monster of a gun" -A Dolskan infantryman in the strategically important Fort Krajow, month after the invasion begun.
