In 2379, the Valdore took part in a battle in the Bassen Rift, along with another Warbird and the USS Enterprise, a Federation starship, against the Reman Warbird Scimitar, under the command of Shinzon of Remus. Shinzon had recently executed a coup d'état of the Romulan Empire, and was planning to eliminate all life on Earth using thalaron radiation.
Believing that Shinzon would lead the Empire to destruction, Donatra assisted Captain Picard and the Enterprise crew in the battle, until the Valdore was critically damaged due to an attack by the Scimitar. After the conclusion of the battle, in which Shinzon was defeated and the Scimitar destroyed, Donatra dispatched shuttles from the Valdore with medical personnel and supplies, in order to assist the Enterprise crew in recovering from the conflict.
