Didn't they say in another thread at TrekBBS they they cut out of bunch of the battle scenes from the D.S.9. pilot from Wolf 359?
The DS9 Companion mentions it, but never really goes into too much detail. I think they mostly took out a lot of debris and derelict ships. The battle scene was initially intended to be set during the end of Wolf 359, but the script was altered to make it the beginning so we could have Locutus' giving his resistance is futile spiel.
