Is this passage properly structured and worded?

FYI- Bareris is the bard. The shocking destruction of Kossuth’s servants nearly caused the legions to succumb to panic and collapse, but Milsantos and the other leaders were able to rally their forces and reestablish order. The Thayan men-at-arms, priests, and wizards fought courageously against the undead, but their eventual defeat still was inevitable. In the hope of changing that outcome, Milsantos and Nymia led a small but elite band of their followers directly against Ysval and a formidable group of undead. While Mirror battled and defeated one of the nighthaunt’s officers, an angel of decay, Bareris was assailed by Tammith, The bard was able to incapacitate Tammith, and he then hacked her to pieces in an attempt to release her from her undead existence. Afterward, Bareris joined Aoth, Brightwing, and Mirror in confronting Ysval, and together they managed to destroy the nighthaunt.
