Battle of Kyūden Tonbo

The Battle of Kyūden Tonbo in the year 704 was the defeat of the Lion Clan who had attacked the Dragon Clan after Akodo Yokutsu's betrothal to a Phoenix maiden was broken to marry her true love, Mirumoto Ashijin. Fields of Victory, p. 36
== Preambles ==
The Lion general Akodo Yokutsu was betrothed to Phoenix samurai Isawa Moroko as part of a series of negotiated agreements between the two clans. Moroko's family held many of the plains to the north of Toshi Ranbo, east of Dragon lands and west of Drowned Merchant River. Before the marriage could take place, Moroko's family broke off the betrothal so that Moroko could marry her true love, Mirumoto Ashijin, and allowed her to retain her inheritance even after she joined the Dragon. Enraged at the loss of Moroko's lands and what he perceived as a personal slight, Yokutsu was granted by his champion for leave to marshal an army and attack the Dragon, but limited the size of Yokutsu's army to avoid any appearance of starting a war unsanctioned by the Throne. 
== Battle ==
In the year 704, Yokutsu led his army to take Kyūden Tonbo, or Dragonfly Palace, Ashijin and Moroko's new holding in the southern Dragon lands. A combined Dragon and Phoenix Clan army had been summoned to defend the couple. In the ensuing Battle of Kyūden Tonbo, Yokutsu made some initial headway, but his army's limited size soon meant he had to commit his small reserve force. Unable to maintain the momentum of the attack, Yokutsu's army was forced on the defensive, and eventually they tried to retreat, but Phoenix shugenja led by Mirumoto Moroko used their elemental power to block the Lion forces' withdrawal. Yokutsu refused an agreement sent by the other party and swore that he would still have Moroko's lands for his own. Fields of Victory, pp. 36-37
== Aftermath ==
Finally, the agreement negotiated between the Lion, Dragon, and Phoenix Clans prompted the Emperor to recognize Moroko, Ashijin, and their followers as members of a new Minor Clan, the Dragonfly. The Hantei granted them the new family name Tonbo. The Dragon ceded to the newly minted Dragonfly Clan the lands south and southeast of the Great Climb (including Moroko's territory). The Dragonfly would act as the Dragon's gatekeepers, receiving visitors and ensuring that only those with approved or important business were permitted to journey onward into the mountains.
