The Battle of Mirkwood, more commonly known as Battle under the trees, was a battle which takes place during the Dark Wars. It is a battle between the forces of Mirkwood, under the command of its Elvenking Thranduil, and the forces of Azog and Sauron from Dol-Guldur.
In the year 2905 3A, Sauron, disguised in the Necromancer in Dol Guldur, sent Azog to lead a legion of 10,000 Gundabad orcs to invade Mirkwood. Thranduil himself repels the enemy, and there is a long battle under the trees. Thara, wh owas Thranduil's wife, was slain during the battle. The woods are set alight, thus there is a "great ruin of fire". In the end of the battle, King Thranduil and his people emerge as victors, announcing a New Year of the Elves.
