Campbell localises this version in Sunart, beside a loch he calls Loch na Dunach, translated as the Loch of Disaster. The guide preserves that source spelling without attaching coordinates or assuming a modern lake-name match. A named setting is useful evidence, but it does not establish the literal truth of what the narrator places there.
The account belongs to the book's chapter on the Water-horse, or Each Uisge. Its decisive early detail is the animal's expanding back. What would ordinarily limit a group of riders no longer does. The scene becomes frightening because the children read that impossible accommodation as an invitation rather than as something to stop and examine.
Touch matters more than pursuit. The horse is not introduced as a charging attacker, and the children do not begin by fleeing it. Their own approach creates the exposure. That makes the tale a severe choice for a water-themed shelf: the danger starts on the bank, while the loch waits nearby, rather than appearing only once someone is already swimming.
Campbell explicitly calls the story widely spread and interprets it as a pious fraud meant to keep children from Sunday wandering and meddling with horses. His sceptical comment should stay alongside the narrative. The Bible carried by one child belongs to the account's religious framing, and any protection it seems to offer is a story element, not practical safety guidance.
The linked account is much shorter than this editorial guide and its violence is abrupt. There is no long character study to soften the consequences, and the content notice names what a reader may wish to avoid. Campbell's volume presents orally gathered tradition, but gives this version no named individual teller.
