Attack on Dol Guldur
The attack on Dol Guldur was an expedition launched by the White Council in Third Age 2941 against the fortress of Dol Guldur in southern Mirkwood.
History
Prelude
When Sauron re-emerged in the Third Age, he established Dol Guldur on Amon Lanc after Third Age 1000. His corrupting shadow, known only as the "Necromancer", came over Mirkwood, and as a result, Thranduil led his people away. The Council of the Wise long feared the Necromancer might indeed be Sauron; Gandalf himself entered Dol Guldur a couple of times, finally confirming that Sauron was its master. At first Saruman opposed the idea of an attack, as he was secretly searching for the One Ring in the area by then, but later, fearing that Sauron was also looking of the Ring, he finally agreed to an attack in Third Age 2941.
The Battle
After leaving Thorin and Company at the outskirts of Mirkwood, he joined the White Council and they marched against the great fortress.
Little is known of the actual battle. It is unclear if this was simply a duel between great powers, or if it involved the use of armies of any kind. Thanks to the devices of Saruman the Wise, Sauron was driven out from Dol Guldur. However, having already made his plans, he fled to his ancient realm of Mordor.
Aftermath
With victory theirs, Gandalf immediately left for Erebor, where he would take part in the Battle of Five Armies. After these events, Gandalf and Elrond discussed their victories and agreed that it would be better if the Necromancer were banished from the world altogether.
However, Dol Guldur was not destroyed; it remained standing, staffed by the lieutenant of Barad-dûr, and later Khamûl. It was not until the War of the Ring that the fortress was finally destroyed.
