Battle of Calder II

The Battle of Calder II was a battle between a Federation fleet and three Romulan warbirds, one of which was a prototype of the D'deridex class, in the in orbit of the disputed planet of Calder II, which was home to massive dilithium deposits. Disobeying orders, the USS Gemini-A warped into the star system and attacked the remaining D'deridex class warbird. The warbird was destroyed, but the victory was a pyhirric one, as the Gemini-A was lost in the process.
