Bard shoots Smaug with his black arrow.
no he is killed by bard
Bard called it "Black Arrow"
In The Hobbit, Bard, who was the King of Dale, can be described as gallant and brave.
Smaug died when Bard the Bowman, using a special arrow given to him by the thrush, shot the dragon in his weak spot on his belly. This fatal shot pierced Smaug's heart, leading to his demise.
The Old Thrush, one of the species of Great Thrush that lived in the Esgaroth region, told Bard that Smaug had a hole in his armored chest right over his heart.
Smaug is the major conflict who is slain by Bard.
The killer of Smaug is Bard the Bowman. He's alerted by a thrush who overheard of Smaug's weakness (a single bare spot in his bejeweled chest).Bard, a man in the town of Esgaroth, a town by the lake, killed the dragon. He was told by the thrush where Smaug's weak spot was, and thus Bard was able to shoot the dragon through the heart.
Smaug was killed when Bard shot an arrow into his heart, aiming for a specific spot on his chest where there was a gap in his nigh-inpenetrable scales.
Smaug has the Arkenstone in his hoard. Bilbo acquires it from the pile of treasure. He then gives it to Bard. Bard puts it with Thorin when he is buried. That is where it stayed.
As the Bard is about the shoot his last of many arrows at Smaug a thrush comes up and lands on his shoulder. He understands the bird because it is from Dale. It tells him to wait for the moon to rise so he can see the soft spot on the dragons breast so he can send an arrow straight through it and kill Smaug. He uses a black arrow and does exactly how he was told. And that was the end of Smaug of Esgaroth, but not of Bard.
Bard the Bowman shot a black arrow into the bare hollow in Smaug's left breast, killing the dragon. The arrow was believed by Bard to have come from the King Under the Mountian, and his father and his grandfather had used it.
