Third battle against the Kin

The Battle Against the Kin took place in Shattered Sky. All clans, including SkyClan (but not StarClan), fought against the Kin, a group of rogues formed by Darktail.

Premise

 * Darktail's group, later the Kin, took over ShadowClan territory. In the clans' first attempt of driving out the Kin, WindClan retreated for no reason, causing the clans to lose the battle, and RiverClan suffering severe damage. Soon, WindClan closed its borders. While RiverClan was still weak, Darktail took that chance and won the RiverClan territory. Those who weren't taken as prisoners left to seek shelter in ThunderClan. After SkyClan returning to its rank among the other clans, and Onestar revealing his secret, WindClan joins all the other clans in fighting against the Kin.

Trivia

 * In Darkest Night, Mistystar listed RiverClan cats who were killed in the battle. However, Perchwing was not mentioned.
