The thirty-thousand-strong army of Lordaeron had already reached the border of Altland, and as soon as they were permitted, they could quickly march into Altland City.
With the addition of this thirty-thousand-strong army, the forces of the Alliance and the Horde changed from eighty thousand to sixty-five thousand, becoming one hundred and ten thousand to sixty-five thousand. Moreover, the Lordaeron army had a high rate of elite troops, far from being comparable to militia, greatly enhancing the Alliance camp's troop quality. With nearly double the numbers, the Alliance now had an absolute advantage.
King Aidan finally had confidence.
Gone was the indecision as he waved his hand, "Then let the King lead the central army, with all the allied nobles forming the right wing, and the Lordaeron reinforcements forming the left wing. The militia will still be used as a reserve force. In three days, we march to Icewolf Tundra for the final battle with the Horde!"
