Moat Cailin enters the account at a moment when Torrhen Stark had to choose between risking battle at the Trident and withdrawing north. It was proposed as the place where he might make a stand on northern soil, but the surrender that followed meant the narrative never shows that plan being carried out.

A Proposed Northern Stand

After crossing the Neck into the riverlands, Torrhen found a larger army waiting south of the Trident, with three dragons circling overhead. His scouts had seen the still-burning ruins of Harrenhal, and accounts of the Field of Fire made the danger of forcing a river crossing plain. Some of his bannermen nevertheless urged an attack; others advised retreat to Moat Cailin, where he could resist on northern ground. The suggestion establishes the location as a possible point of withdrawal in the crisis, without describing its defenses or the practicalities of a stand there.

The Choice at the Trident

The proposed retreat was not the course Torrhen took. His bastard brother, Brandon Snow, had offered to cross the river by night to kill the dragons, but Torrhen sent him with three maesters to negotiate instead. Messages passed between the camps through the night. The next morning Torrhen crossed the Trident himself, laid the ancient crown of the Kings of Winter at his opponent’s feet, and swore fealty. He emerged as Lord of Winterfell and Warden of the North rather than a king.

Place in the Account

Moat Cailin matters here as the unchosen alternative to a potentially ruinous battle: the account sets a northern retreat against the dangers of attacking across the Trident, then resolves the crisis through negotiation and submission. No battle at Moat Cailin is described, and the text does not say that Torrhen reached or occupied it during this episode.
