Are these two sentences properly worded?

FYI- Szass Tam is the lich. Szass Tam then informed the assembly that the Red Wizards of Necromancy would utilize the usable corpses of Thayans to manufacture undead soldiers to reinforce the two governors’ forces, and that he would send many necromancers to help them eliminate the undead horde. The lich also convinced Iphegor to command several of the church of Kossuth’s militant orders to join the fight against the undead, and he supplied the priests with magical torch-like weapons to aid them.
