First War of the Woodland Realm

The First War of the Woodland Realm was a brief war between the Red Dwarves and the Wood-Elves.

Background
The beginning of this war was sudden and unexpected. A petty quarrel between members of the two facs blew up into a major argument. As neither side was willing to budge, the Red Dwarves decided to force the matter by declaring war.

Events
(Note: My knowledge of the latter sieges of the war is lacking, please expand if you can!)

The first siege took place shortly after war was declared. The Red Dwarves, with some of their western kin as allies, marched up to the gates of Mirkwood's capital. Thranduil (SiDeus) also brought some (elven) allies, but this turned out to be a mixed blessing, as one of the elven defenders accidentally shot a couple of his allies over the walls. In the end, the Red Dwarves carried the day, and won the first siege.

After this battle, the Dwarves of Erebor and the Blue Mountains officially allied with the dwarves of the Red Mountains. The Wood-Elves, however, were unable to generate support for their cause, and were largely left without allies. Thus, in the second and third sieges, the Wood-Elves were again handily defeated by the Dwarves. Seeing that the war was lost, Thranduil (SiDeus) gave the kingship to Arthane (Galin_The_Great), who surrendered soon after.

Aftermath
Although he was allowed to keep the kingship, Arthane was essentially made a vassal of the Red Mountains. This war, however, set the stage for the beginning of the end of the Red Mountains. Elated by his victory, King Taendell would then launch the War for Dunland, then fall in the War of Honor.
