The Pi Canis Campaign was an extended military campaign spearheaded by the late USS Adagio. The Adagio was sent behind Klingon lines by Starfleet Command to interfere with enemy operations. The campaign took place over the summer of 2413.
The USS Adagio breached enemy lines on April 30th, 2413. Over the next few months, the Adagio would interfere with Klingon operations. The Adagio returned to Federation space through an unstable wormhole on June 25th, 2413. The Adagio had sustained severe damage and was decommissioned shortly afterwards.
