Now equipped with the strongest army and navy in Westeros, Stannis attempts to capture the capital city of King's Landing by sea, but many of his men are killed when Tyrion Lannister detonates jars of wildfire in the Blackwater River and burns most of his fleet. Stannis' forces still nearly claim victory, but Lannister and Tyrell reinforcements arrive in time to drive Stannis' men away from King's Landing. However, with the help Rolland Storm, the Bastard of Nightsong, Stannis flees to Dragonstone to fight another day.
