Redwyne Straits is the sea passage guarding the approach to the Reach and Oldtown, but in the book it is defined less by geography than by danger. During the ironborn offensive, the straits become a contested corridor where ordinary travel is exposed to piracy, naval weakness, and the wider consequences of Euron Greyjoy’s expansion. Its waters transform the last stage of Samwell Tarly and Gilly’s voyage from a homeward passage into a narrow escape.

A Maritime Front in the Reach

Redwyne Straits are dangerous because the ironborn have converted the surrounding coastline into a chain of raiding bases. With the principal strength of the Arbor’s fleet stationed on the far side of Westeros, the ironborn have sacked Ryamsport and seized Vinetown and Starfish Harbor, using both ports to prey on ships bound for Oldtown. Their attacks are not confined to isolated vessels: they have raided up the Mander, assaulted the Arbor and its neighboring islands, and overwhelmed, captured, or sunk the dozen warships left to defend the Redwyne home waters.

The straits therefore embody a larger strategic reversal. The Reach, normally associated with abundance, commerce, and naval protection, is presented as a region whose maritime defenses have been stripped away. Reports that longships are moving through Whispering Sound toward Oldtown extend the threat beyond the islands and into the heart of the Reach’s coastal network. Redwyne Straits are the point where that threat becomes immediate for anyone attempting to reach the city by sea.

The Cinnamon Wind’s Passage

The final and most perilous portion of the Cinnamon Wind’s voyage comes in the Redwyne Straits after the ship’s passengers have already been warned of the danger. Three longships are sighted from the crow’s nest. Two remain well astern, allowing the Cinnamon Wind to outrun them, but the third appears near sunset and attempts to cut the ship off from Whispering Sound. The encounter gives the straits a precise tactical character: they are not merely a region known to contain enemies, but a constricted approach in which a faster ship can still be intercepted.

Kojja Mo responds before the longship can close. She sends her archers to the castles, where they use great bows of goldenheart, weapons capable of sending shafts farther and more accurately than even Dornish yew. She waits until the enemy ship is within two hundred yards before ordering the volley. Sam looses an arrow with the others and believes it reaches the longship. The single barrage is enough to force the vessel to veer south in search of easier prey, so the Cinnamon Wind survives without a prolonged boarding action or a second exchange.

The episode makes the passage of the straits depend on disciplined timing rather than luck alone. Kojja Mo does not waste her first opportunity by firing too soon, and Sam’s participation gives the danger a personal dimension: the voyage’s supposedly least martial passenger is drawn into the defense of the ship. The ironborn vessel is not destroyed, but its retreat is sufficient to preserve the travelers’ route toward Oldtown.

The Threshold of Oldtown

After the attack, deep blue dusk falls as the Cinnamon Wind enters Whispering Sound. The danger of the Redwyne Straits has not vanished into a triumphant naval victory; it has simply been survived. The ship’s arrival at the sound marks the end of the exposed passage and the beginning of the final approach. Gilly stands at the prow with the baby and looks toward Three Towers, the castle of House Costayne, while Sam identifies it for her.

The sight is splendid, with torchlight flickering from the windows against the evening stars, yet Sam is saddened by it because the voyage is almost over. This response gives the straits a second function in the narrative. They are a physical threshold between perilous movement and arrival, but also the last stretch of a journey whose ending carries emotional weight. The passage closes not with complete security, but with the travelers looking toward a landmark that confirms their destination is near.

Strategic and Narrative Significance

Redwyne Straits connect several scales of the story. At the local level, they are the waters through which a single ship must evade an intercepting longship. At the regional level, they expose the failure of the Redwynes’ remaining naval defense and the ironborn occupation of coastal bases. At the political level, the crisis helps explain why control of Dragonstone and the release of Lord Paxter Redwyne’s fleet matter to the crown: a fleet freed from one obligation might be used to drive the ironborn from the Shield Islands and restore the Reach’s maritime security.

The straits also stand beside other objects and routes that carry knowledge, danger, or power across distant communities. The glass candles in the Citadel preserve a mysterious Valyrian inheritance; dragonglass links the Children of the Forest, the Night’s Watch, and the threat of the Others; Euron Greyjoy’s dragon horn claims to bind dragons through a relic recovered from Valyria; and Jaime Lannister’s golden hand turns bodily loss into a public emblem of identity. Against these extraordinary objects, the Redwyne Straits remain a concrete boundary where naval technology, intelligence, and coordinated action determine survival. Their importance lies in making the book’s vast conflicts tangible: empires and prophecies ultimately press upon a ship, a coastline, and the distance between one safe harbor and the next.
