Eastwatch-by-the-Sea is the easternmost castle of the Night's Watch along the Wall, located on a grey, windswept shore by the Bay of Seals. To the west lies Greenguard, an abandoned castle. Some fisherfolk live near Eastwatch.
The Night's Watch keeps several galleys at Eastwatch, including larger vessels capable of crossing the narrow sea, and lean fighting vessels. The galleys patrol the Bay of Seals, and sometimes catch smugglers who trade weapons to the free folk. Ships stationed at Eastwatch include Talon, Blackbird, and Storm Crow.
Some free folk trade with the Night's Watch at Eastwatch; wildlings prefer it to Castle Black, because trading ships visit from across the narrow sea. Sure-footed mules, that can handle the ice of the Wall, are bred by the Watch at Eastwatch.
Maester Balder wrote The Edge of the World while serving at Eastwatch. Maester Wyllis, who studied the customs of the free folk and lived among them, was last seen at the docks of Oldtown hoping to find transport to Eastwatch.
Half a year after the Night's Watch rebellion of 50 AC was put down and Ser Raymund Mallery and his men fled beyond the Wall, his head was delivered to Eastwatch by a free folk chieftain, who claimed that Raymund's rebels had been eaten.
In 219 AC, Aegor Rivers was captured at the end of the Third Blackfyre Rebellion, and King Aerys I Targaryen decided to sentence him to join the Night's Watch. However, the ship taking Aegor north to Eastwatch was intercepted en route, and he returned to the Golden Company and his support of House Blackfyre in exile.
When Maester Aemon took the black, Ser Duncan the Tall accompanied him on Golden Dragon to see him safely to Eastwatch. Among those aboard who had been sent to the Wall by King Aegon V Targaryen to join the Night's Watch alongside Aemon, was Brynden Rivers and many of the Raven's Teeth.
Before Robert's Rebellion, when Davos Seaworth was a smuggler, he traded at Eastwatch. In his youth, he served on the Cobblecat, captained by Roro Uhoris. The ship was taken by galleys from Eastwatch for the crime of trading weapons to the free folk, and Roro was beheaded at the castle.
One brother at Eastwatch is a man who set his father's house on fire, and barred the door. All nine members of his family burned to death.
A Game of Thrones
There are fewer than two hundred men stationed at Eastwatch under the command of Cotter Pyke. Tyrion Lannister and the officers of Castle Black enjoy succulent crabs shipped from Eastwatch. Jeor Mormont, Lord Commander of the Night's Watch, tells Tyrion there are reports that fisherfolk near Eastwatch have seen white walkers.
A Clash of Kings
Tyrion, the acting Hand of the King, sends Janos Slynt and Allar Deem to join the Night's Watch, discreetly arranging for Allar to be tossed from Summer's Dream while the carrack sails for Eastwatch.
A Storm of Swords
Cotter captures Rattleshirt at Long Barrow, and the wildling reveals that Jon Snow killed Qhorin Halfhand. Alliser Thorne and Ser Glendon Hewett are among a small group of Eastwatch men who escort Janos Slynt to Castle Black. Janos takes command of Castle Black in the absence of Bowen Marsh, and he has Jon arrested.
King Stannis Baratheon and his forces sail to Eastwatch, then ride west with Cotter's scouts to defeat Mance Rayder's host in the battle beneath the Wall. Queen Selyse Florent, Princess Shireen Baratheon, and Stannis's fleet remain at Eastwatch. Vindicated by Stannis, Jon trains with the promising Iron Emmett, one of Eastwatch's best rangers. Instead of Cotter or Ser Denys Mallister, Jon is chosen as the new Lord Commander after Jeor's death.
A Feast for Crows
A Dance with Dragons
Lord Davos Seaworth and Salladhor Saan sail from Eastwatch for White Harbor, while Selyse and her queen's men travel from Eastwatch to Castle Black. Lord Commander Snow sends his friends Grenn and Pypar from Castle Black to Eastwatch. When Melisandre has a vision of submerged towers by the sea, Jon ponders if it is Eastwatch.
In order to save thousands of wildlings trapped at Hardhome, Cotter Pyke leads eleven ships in a rescue mission, with Glendon Hewett remaining to hold Eastwatch. Bowen Marsh is tasked with collecting the treasures of wildlings crossing the Wall south, and having the tolls sent to Eastwatch. Because their mammoths are too big to travel through the Wall at Castle Black, the giants are sent east to round the Wall at Eastwatch.
—thoughts of Davos Seaworth
Those look like Eastwatch men. Sailors on horses.
—thoughts of Varamyr
At Eastwatch I was patient ... and cold, so very cold.
