Seven Years' War
The Seven Years' War was the first war in a century fought between the Reach and the Westerlands, lasting between 52-59 A.I. The conflict was fought predominantly in the Foote Hills in the Southron Westerlands, with Andal adventurers fighting on both sides of the conflict. In the end, the Reach was driven from the Footehills and had to give up control of Goldengrove to Andal adventurer Jasper Risley.
Background
The Westerlands had expanded greatly in the last decade, with King Brandon Crakehall having set aside his crown to bend the knee to the Lannisters c. 42 A.I. Soon after, the Crakehalls, with the aid of the Risley’s, invaded the few remaining Footehill clans, conquering them and driving them out of the silver mines of Silverhill.
The escaping clansmen made their way to the Reach, begging the Gardeners to help them take back their homelands. With King Gwayne Gardener missing, his eldest son Mern Gardener took up kingship and agreed to aid the clansmen. He surmised that the Westerlands was gathering forces, especially Andals, to invade his realm. Gathering the banners of houses Crane, Rowan, Hightower, Webber, Peake, Manderly, Oakheart, Fossoway and Andal adventurer Daelwell, a force some twenty-five thousand strong, Mern began the march on the Footehills.
On the other side were the forces of the Lannisters and their banners: Lantell, Reyne, Crakehall, Banefort, Lannisters of Lannisport, Dale, Westerling, and Andal adventurers Risley and Vypren, the latter being promised lordship of Silverhill. Some sixteen thousand strong.
Seventeen battles had been fought overall. Three of them were a victory for the Reach. The overall forces of the Rock were lead by Jasper Risley in every single battle, while the Reach had multiple different commanders. The first few battles were lead by Lord Peake, who succumbed to his battlewounds after the third battle. The next Reach commander was Daelwell, who ended up dying due to his ailing health. Soon enough Mern Gardener was killed in battle.
With winter approaching, both sides came to an agreement to end the war. Control of Goldengrove and some of its surroundings territories were ceded to House Risley. Both kingdoms were terribly bloodied, the Reach losing some thirty thousand men, with the Rock losing some ten thousand.
