Despite the Narnians' courage, they were still defeated due to Jadis' extremely powerful dark magic.

Against hope, the Narnian King led an army of men, talking beasts, dwarves, centaurs, and good giants against Jadis. Aslan did not yet come to the aid of the Narnians, who were forced to fend for themselves. Narnia's worst fears were realised two years after the tree's death, when Jadis invaded Narnia from the north west with an army of evil creatures from which was the Witch Country, which lay north of the Western Wild and Telmar, south of the Unnamed Tundra, east of the Western Sea, and west of the Wild Lands of the North. The wind blew from the northwest and was unusually powerful, leading some of the wiser creatures in Narnia to wonder whether it had been supernaturally contrived by the mysterious sorceress Jadis, who had a sinister reputation in Narnian folklore. However, in the Narnian year 896, the ancient Tree of Protection was blown down during a violent storm, fulfilling the prophecy Aslan spoke at the tree's planting on the day of Narnia's creation. Time after time during this era, Aslan would appear in Narnia at the Stone Table to advise Narnians threatened by various evils (unaffiliated with Jadis). It was during this era that Archenland, Galma, Terebinthia, the Seven Isles, the Lone Islands and the Merpeople's sea nation were formed and became allies or territories of Narnia, ergo the Narnian Empire was formed.
