The episode "Defiant" was in November 1994, so it was very close to the start of VOY in January 1995.
Ah, good. so basically that's the last major thing to involve the Maquis before Voyager gets trapped in the Delta Quadrant. Later, in Improbable Cause
, we find out that the secret fleet was being built to fight the Dominion, and that attack was the catalyst for change in the Alpha Quadrant, with the Obsedian Order getting wiped out.
Anyway, as this relates to ST: Voyager
, the Maquis on Voyager have no idea what's going on in the Alpha Quadrant during all this, so as far as they know the Maquis are still fighting the good fight.
