- A Klingon faction enacts a plan to draw off Starfleet assets and sabotage the defenses of Starbase 12, so that a single, over-armed cruiser can slip through the Typhon Expanse and destroy the strategic starbase. The plot is foiled when the Soyuz-class border cutter USS Bozeman detects and engages the much larger cruiser. The Bozeman's actions allow reinforcements to arrive in time to protect Starbase 12, but the ship itself vanishes. A massive search operation is conducted for weeks, but no trace is found. The Bozeman in fact entered a temporal anomaly, re-emerging in 2368.
