Upon starting the deadly contact campaign I first referred to several cannon resources to learn more about the Cardassian war. I found none. TNG episodes like "The Wounded" referred to the war, but did not point out the length of the war. "DS9: Tribunal" tells us that Captain Maxwell's family is killed around 2348 by a Cardassian Raid, almost 20 years before The Enterprise D is launced. My own idea was that the war was rather a series of skirmishes that sometimes exploded into larger conflicts. The beginning of the war was the bloodiest. After the initial few months, the conflict stabilized, and began the border skirmishes described. The following timeline is the guideline I used to build the story on which the missions are based.
A Cardassian civil war begins. The Cardassian Commonwealth is split between the Civilian leadership, the Obsidian Order, and The Military. The Obsidian Order and military soon join forces.
