The Gilneas Brigade was sent by Darius Crowley, a Gilnean noble and dissident. Crowley's lands were split by the Greymane Wall and sent the Brigade in an act of defiance against Genn Greymane before the Northgate Rebellion.
While in service to Jaina the Gilneas Brigade would form an encampment and aid in guarding the passage into the Stonetalon Peaks. Some time later the encampment came under attack from Grom Hellscream and the Warsong clan. In response the brigade struck back against the rest of the Horde.

The Gilneas Brigade is one army of the Alliance in the Broken Isles, moving against the Burning Legion and Sylvanas Windrunner's forces under King Genn Greymane's command. The bulk of the Gilneas Brigade now comprise of Gilnean worgen. Whether this Brigade has any connection to the one from the Third War is unclear.
The Gilneas Brigade established Greywatch to secure Stormheim from threats. The original Gilneas Brigade's founder, Darius Crowley, along with his daughter, Lorna Crowley, are both members of the contemporary Gilneas Brigade. The Crowley family fought with King Greymane on the Skyfire as they assaulted Sylvanas' fleet and brought Alliance reinforcements to the Broken Isles. At Stormheim, Lorna would lead Gilneas Brigade scouts and aid Greymane's mercenaries in undergoing the various ancient trials necessary to obtain the Aegis of Aggramar. Eventually, the Gilneas Brigade uncovers that the Forsaken means to plague Greywatch like they did Gilneas. Greymane commands his forces to destroy the plague caches and the invading Forsaken apothecary to secure Greywatch and later sends Lorna to uncover what Sylvanas seeks in Skold-Ashil. As Lorna discovers that Sylvanas means to create more Val'kyr by subjugating Eyir, Genn musters the Alliance fleet in trying to assault Dreadwake's Landing. The battle at Greymane's Offensive goes poorly and his offensive is repelled. After hearing news of Lorna's intelligence, Genn personally goes to the vault in Skold-Ashil and prevents Sylvanas from subjugating Eyir.
