Is this short paragraph correctly worded?

Quenthel revealed to the Armgos that House Do'Urden would lead the fight in the Silver Marches, but all the Houses of Menzoberranzan and Q'Xorlarrin would contribute representatives to the force sent to the surface. However, the actual drow contingent would not be large, and Lolth and Quenthel’s plan was that the dark elves would instead utilize the orcs of Many-Arrows. The vast army of the orc kingdom would do the majority of the fighting against the peoples of the Silver Marches, while the drow would primarily serve as advisors who directed the offensive. This strategy ensured that no matter the outcome of the war, the drow would not suffer any serious losses themselves.
