Hath siege of Tivoli
From Tardis Wiki, the free Doctor Who reference
On 8 December 3001, the Hath laid siege to the planet Tivoli, which they had earlier lost to an Ogron invasion on 14 January 2064, and chased off the Drahvins. As before, the Hath were welcomed as heroes by the native Tivolians as the rule of the Drahvin, which had stood since they subjugated Tivoli and eradicated the occupying Shakri on 17 November 2900, came to an end.
