Dol Guldur
During the final days of the War of the Ring, Dol Guldur sent forces against Lothlórien and Thranduil's realm in what came to be known as the Battles of Lothlórien and Mirkwood: three attacks on Lórien (March 11, 15, and 22) and one, "The Battle under the Trees", against Thranduil (March 15). All were fiercely fought, but the power of Galadriel and the strength of the Elves proved too great for Dol Guldur to overcome. After the defeat of Sauron on March 25, Celeborn marched on Dol Guldur and overthrew it. Galadriel then destroyed the fortress so that the forest was free from the shadow of the tower.
