Captain's Log Stardate 1107.30 USS Guadalcanal, Portas Sector, in Pursuit of Hijacked Convoy

Captain's Log, Stardate 1107.30. Captain Murphy recording

Entering Portas Sector on the edge of Breen space. Little has been heard
from the Breen since the end of the Dominion War. The ship that we
encountered at the outer fringe of Breen space bore no resemblance to
anything on the Starfleet database, and we find that the trails we've been
following have gone dry. Attempting to stop the unidentified heavy cruiser,
we were unable to establish communication. Did they receive but refuse to
answer? Were they unable to receive or understand? Readings are
inconclusive. In any case, the unidentified ship attacked us, and we were
forced to respond in kind. Apparently the alien ship had a flaw of some
kind, because our weapons completely overwhelmed their defenses, and they
were destroyed. Sensor logs have been flash transmitted to Starfleet. Combat
proceeded as follows:

Unidentified Heavy Cruiser Multiplier X5
USS Guadalcanal Heavy Cruiser Multiplier X5

Unidentified Heavy Cruiser Rolls 30 Allocation: 15,15
USS Guadalcanal Rolls 45 Allocation: 30,15

Result:
Unknown Heavy Cruiser: Destroyed
USS Guadalcanal: Undamaged
