Is this small passage all strcutured and worded correctly?

For her assault upon the Tower, Kitiara intended to only use three blue dragons, leaving the rest at Vingaard Keep. The highlord was extremely confident since the majority of the Solamnic army had been wiped out two days earlier, and now only a small force defended the fortress. Sturm and Laurana, in command of the remaining knights, assembled their troops, armed with dragonlances, in the dragon trap alcoves.
