See also Fan Fiction/Battle Of Molecay
The Battle of Molecay was a major engagement between Cylon forces and the Fifth Fleet (including the battlestar Pegasus), approximately two yahrens prior to Pegasus's miraculous re-discovery by Galactica and her civilian Fleet after the destruction of the Colonies.
This fleet, under the command of Commander Cain, was apparently destroyed (TOS: "The Living Legend, Part I").
Cain and Pegasus survive the encounter, and later meet up with the rag-tag Fleet being led by Galactica, where Cain works to incite an attack on Cylon forces at Gamoray (TOS: "The Living Legend, Part I").
