If the Orcs Forces that reached the Main Road first chose to head east along it and quickly attack Menethil City, the garrison left there would have no hope of holding the city. By the time the Allied Army Main Force arrived, corpses might already litter the streets, and the city might be entirely in orc hands.
The elves and Human Alliance troops here would also find themselves in a desperate position, cut off from the fleet at sea.

Once they secured a landing bridgehead, they would need only a portion of their death knights to create a Path of Frost across the sea, made entirely of enormous ice floes linking the two shores. This would allow the Orcs Main Force south of the strait to cross that natural barrier quickly.
Still, there were no death knights among the Orcs Forces that had entered the Wetlands. For Proudmoore's Alliance forces in the Wetlands, this was the best—and only good—news the Allied Army there had received in days.
