According to "The Wounded", the Federation and the Cardies have been at war for decades. We never saw any of this on-screen, the first we hear of it is in that episode, which deals with the fall-out and of both sides making a hard readjustment to peace-time.
It's kind of hard to credit that this 'war' is going on in the background through TNG's first three seasons. One would imagine that the 'war' would be much more front-and-center for the Enterprise and her crew. Everything is too laid-back in TNG's era for them to be facing this kind of conflict.
So: why didn't we see more of this, prior to "The Wounded"? Are we to suppose that the Cardassian 'war' is in reality more like isolated incidents and skirmishes, than it is an intergalactic conflict?
Maybe the Federation and the Cardassian Union are in a technical state of war, but it isn't depicted (on-screen at least) as a sustained conflict with territorial borders, or even a Cold War style "see who blinks first" conflict ala the Klingons or Romulans.
Or, maybe the reason TNG seasons 1-3 don't depict this so-called state of 'war' is because by then the conflict was already simmering down. It would appear that the height of the war, the massacres and combat scenarios, all happened prior to TNG's first season, even though as I say on a technical level a state of war still exists, the actual incidents of conflict have vastly diminished by the time even of TNG's first season.
What we hear of this Cardassian war, in both TNG and DS9, certainly sounds brutal enough. Setlik III is held up as the lynchpin, but it is clear that ship-to-ship combat was often the case. Picard mentions an incident where USS Stargazer faced down a Cardassian opponent and had to flee, and USS Rutledge and USS Tecumseh are also said to have seen extensive combat, so maybe it was simply down to patrol areas, and certain vessels saw the brunt of the conflict more than others.
Certainly the war was so bad that the Federation is willing to capitulate quite significantly when it comes to the moving of borders and the establishment of an demilitarized zone, conceding a lot to the Cardassians in the process. Hence, the events of "Journey's End" and "The Maquis".
