The Command to Guard the Tree of Protection

The Command to Guard the Tree of Protection is Aslan’s charge to the Narnians after Digory plants the silver apple’s seed. It gives the new Tree a double significance: the Tree shields Narnia from the Witch, and the command makes its protection a collective duty, tied to the moral character of the kingdom as well as its safety.

The Tree as Narnia’s Shield

As the assembled crowd looks at the Tree, Aslan tells the Narnians to make guarding it their first care. Its branches seem to cast light rather than shade, and silver apples shine among its leaves. The Tree is not merely a marvel to admire: Aslan names it Narnia’s Shield and explains the specific protection it provides. The Witch has fled far north and will grow stronger in dark Magic, but while the Tree flourishes she will not come down into Narnia or approach within a hundred miles.

The Tree’s protection works through a contrast of effects. Its smell brings joy, life, and health to the Narnians, but causes death, horror, and despair to the Witch. The command therefore concerns the continued flourishing of a living safeguard: Narnia’s security is bound to the Tree’s continued presence, and the Witch’s distance is enforced by the very quality that nourishes the land.

Why the Tree Must Be Guarded

The command follows Digory’s deliberate fulfillment of the garden’s instruction to take fruit for others rather than for himself. He carries the apple untasted and plants it in Narnia; the Tree that grows from it is consequently both a defense against the Witch and the outcome of an act undertaken for the kingdom’s good. Its origin matters to the protection it offers. Aslan explains that if a Narnian had stolen an apple and planted it unbidden, the Tree would still have protected Narnia, but the country would have become a strong and cruel empire like Charn rather than the kind land Aslan intends.

That distinction makes guarding the Tree more than a matter of preserving a useful barrier. The Narnian people are charged with protecting a source of safety whose founding is linked to restraint and service to others. The rule’s force is therefore at once practical and ethical: the land must remain protected from the Witch without turning protection into a justification for cruelty.

The Witch’s Threat and the Command’s Legacy

Aslan does not present the Witch’s retreat as her defeat. She has eaten an apple and gained unwearying strength and endless days, and she will continue growing stronger in dark Magic. The Tree limits her access to Narnia, setting a hundred-mile boundary, but the command to guard it acknowledges that this protection depends on the Tree flourishing. The danger remains beyond that shield.

The later history of Narnia confirms the command’s significance. The Beasts live in peace and joy for many hundred years, and neither the Witch nor another enemy troubles the land during that time. The Tree’s protection belongs to the founding order of Narnia: Aslan’s charge joins the kingdom’s long peace to the ongoing care of the living shield that Digory planted.
