Definitely a strange battle with the Borg. Glover fell to the common error of tunnel vision during battle - he was so intent on pursuit he did not realize the Borg were luring him into a trap until it was too late. Fortunately, he was able to salvage the situation (even if by chance) and level the playing field.
Gul Dukat is the wild card. If they succeed in destroying the Borg scout ship, it might provide opportunity for Dukat to attack Cuffe
. Her loss could be attributed to the Borg. I'm sure the thought has crossed Glover's (and Sisko's) mind.
Lots of ways this could still go sideways!
