"Toccata" is a story about the USS Shiloh, originally part of the Star Trek: Shiloh fan fiction website but now part of the Star Trek: Black Hawk fan fiction website. It is a crossover and happens during the first few minutes of Star Trek: First Contact, tied to the end of "Mission to Dosiania", where the Shiloh responds to the general alert and rushes to Earth to help the fleet against the Borg attack.
