"Torwold Browntooth and the Red Oarsman lead twelve ironborn longships up the river Mander to draw out the defenses of the Shield Islands. Instead of sailing along the Reach's coastline, Euron leads the other ironborn ships into the Sunset Sea and attacks the Shields from the west, with the setting sun hiding their approach.
Ser Harras Harlaw lands at Grimston and plants his standard beneath the castle walls. Daring the defenders to face him, he kills five and forces two to yield. After the seventh man is defeated the septon in the castle declares the gods have spoken and surrenders the castle. The islands of Greyshield, Greenshield, and Southshield are captured before the next morning, while Oakenshield lasts half a day. Euron uses Oakenshield Castle at Lord Hewett's Town as his base, with Lord Humfrey Hewett and his family captured.
When the Shields' ships abandon Torwold and the Red Oarsmen in the Mander and return to the islands, they are trapped by the Iron Fleet at the river's mouth. Lord Captain Victarion Greyjoy slays Ser Talbert Serry during the boarding of a Serry vessel when Talbert falls overboard. Victarion loses only six ironborn ships, including Hardhand, but captures thirty-eight. Victarion allows a dozen southron ships to escape to the Mander."
