The Riga-class frigate SLS Admiral Schone was one of the Star League Defense Force WarShips to survive the Hegemony Campaign that liberated Terra from the forces of Stefan Amaris. The Admiral Schone followed General Aleksandr Kerensky on the Exodus, but when the Pentagon Civil War began to erupt on the various worlds settled by the SLDF refugees in the Deep Periphery the Admiral Schone was one of the ships which didn't follow Nicholas Kerensky and his followers to Strana Mechty, instead remaining behind in the Pentagon worlds.
When Nicholas Kerensky launched his new Clans on a campaign to conquer the Pentagon worlds named Operation KLONDIKE in July 2821 the Admiral Schone was one of two ships found to be guarding Arcadia, presumably under the control of one of the many factions on that planet at the time. After securing the naval cache in the Arcadia system, two Clan WarShips operating under the overall command of Khan Absalom Truscott jumped from the naval cache in the Arcadia system to pirate points arond the planet, as did two Clan WarShips originally assigned to secure the Arcadia jump point. Two of these ships approached the Admiral Schone; the Admiral Schone responded by initially issuing a warning challenge to the two Clan WarShips, but soon followed this with a broadcast surrendering to the Clan forces. When a Clan DropShip was deployed to board the Admiral Schone the crew breached their claim to have surrendered by firing on and destroying the Clan DropShip.
The Admiral Schone then broke orbit and attempted to engage the two Clan WarShips sent to secure it, but was unable to maneuver into position to target either ship with it's naval autocannon; the Admiral Schone's other weapons scored several hits on the Clan ships, but the two Clan vessels quickly engaged and destroyed the Admiral Schone. The crew of the Admiral Schone continued to refuse to surrender, and the ship was on fire and decompressing when it fell into Arcadia's atmosphere; not all of the Admiral Schone burned up on reentry, and the ship's remains ended up falling into a region of the southern oceans approximately twelve hundred kilometers wide. Even as late as the thirty-first century fragments from the Admiral Schone would still occasionally be brought to the surface by fishermen or would be washed up along Arcadia's shorelines.
