|Theater of operations|
The Bristlebacks of Brambleblade Ravine are at war with the tauren of Camp Narache and they encroached on the area of Red Cloud Mesa. They train Battleboars to be malicious. Young tauren entered the ravine and killed the Bristleback leader Chief Sharptusk Thornmantle. The quilboars also ravaged the tauren burial site of Red Rocks.
In the Barrens they were at war with the Razormane quilboars. At the start of the war against the Lich King, Bristlebacks became more aggressive and killed a female tauren and her young son. When Hamuul Runetotem performed ritual for the deceased in Red Rocks a few of them attacked the Archdruid.
During the Shattering quilboars of Mulgore were in turmoil. New High Chieftain Baine Bloodhoof stopped the war against them allowing them to take resources from a newly-created river. Some time later, the Bristlebacks attacked the Red Cloud Mesa tauren once again.
