6012

In 6012, the joint human-Hath colonisation of the planet Messaline turned into a short war. It lasted only seven days -- from their arrival on 17 July to the Tenth Doctor's intervention on the 24th -- but involved many generations of clone soldiers, including Jenny. Eventually, the survivors, with little memory of their roots, came to a cease fire and started colonising. (TV: The Doctor's Daughter)
