The Invasion of Capory was an assault by the Romulans on the Human colony world of Capory.
At the time of the invasion, United Earth forces were preparing for an assault on Berengaria and Earth Starfleet forces weren't available to defend the system. Additionally, the Romulans launched a simultaneous attack on Andoria. (ENT novel: Beneath the Raptor's Wing)
There was very little combat at Capory because of the low availability of Starfleet warships. Gannet Brooks reported detonations over the planet itself. (ENT novel: Beneath the Raptor's Wing)
Admiral Valdore's fury at losing at Andoria was lessened by the victory at Capory, though he was suspicious of the lack of Earth warships. (ENT novel: Beneath the Raptor's Wing)
