Davos is given command of a ship at the Battle of the Blackwater, though he disagrees with their commander, Stannis's brother-in-law Ser Imry Florent. Tyrion Lannister, who is Iron Throne's acting Hand of the King in charge of defending King's Landing, traps Stannis' vanguard fleet with a river chain and destroys much of them with wildfire. Davos's four oldest sons are killed in the ambush, but Davos survives and is washed ashore on the seamounts known as the Spears of the Merling King, losing his "luck", and is eventually recovered by Stannis' men.
