|Conflict || War of the Five Kings|
|Date || 299 AL|
|Place || Crag, The Westerlands|
|Result || Stark victory|
The Battle of the Crag was one of the many minor Stark victories in the Westerlands.
After winning the Battle of Ashemark, the Starks moved on to the Crag as part of Robb Stark's plan to draw Tywin Lannister west and out of the Riverlands.
The Crag was stormed, with Smalljon Umber and Black Walder Frey scaling the walls, while Robb Stark broke through the main gate. 
Robb Stark took a wound and was nursed back to health by Jeyne Westerling. During the nursing, Robb deflowered Jeyne, and being an honorable man, married her shortly thereafter. As a consequence of that the Westerlings joined with House Stark.  However by marrying Jeyne, Robb broke his alliance with House Frey, which would shatter his forces.
