Tales From Wilderland
Bard was descended from Lord Girion of Dale, whose wife and child had escaped to Laketown when Smaug ruined Dale and took the Lonely Mountain in TA 2770.
In TA 2941, when Smaug emerged from the Lonely Mountain and attacked Laketown, Bard, as captain of a company of town archers, was encouraging the archers and urging the town Master to order them to fight to the last arrow. Bard himself fired many arrows with his great yew bow. He was down to his last arrow when a thrush came and perched on his shoulder. Because Bard was of the race of Dale, he was able to understand the thrush’s words. The bird told him of the weak spot in Smaug’s armor that Bilbo Baggins had discovered. Bard fired his Black Arrow and struck the hollow by Smaug’s left breast and the dragon fell from the sky, landing on Laketown and destroying it.
After the Battle of Five Armies, Bard went to his ancestral home of Dale at the foot of the Lonely Mountain. He rebuilt the ruined town and in TA 2944, he became King of Dale. Bard maintained good relations with the Dwarves of the Lonely Mountain and trade flowed freely up and down the River Running. People came to settle in Dale from miles around and the land that had been withered by Smaug became bountiful once more.
