|Alias||The Little Lion|
|Book(s)||The Sworn Sword (mentioned)|
Ser Wilbert was the youngest of five brothers and so earned the name the Little Lion in childhood. He grew to be a tall, valiant knight. When Gyles the Third, King of the Reach, was battling the Storm King in the east, the King of the Rock, Lancel IV Lannister, attempted to cut a piece out of the Reach for himself. It fell to Ser Wilbert to stop him with his older brothers off in the east with the King. During the battle, Ser Wilbert came face to face with the King of the Rock. The King had a Valyrian sword, Brightroar, and chopped the Little Lion to bits, but as Ser Wilbert was dying, he drove his dagger into a gap in the King's armor and killed him. The Westerland army collapsed and the Reach was saved.
