"Small Victories" is the first episode from season four of the science fiction television series Stargate SG-1. Penned by Robert C. Cooper and directed by Martin Wood, the episode first aired on the American subscription channel Showtime on June 30, 2000. "Small Victories" resumes the story of the season 3 finale, "Nemesis", in which the SG-1 team encountered the Replicators for the first time. As the Replicators threaten Earth and the Asgard home galaxy, the team must split to master their job. "Small Victories" was another visual effects milestone for the series. The Replicators and the Asgard character Thor were computer-animated for parts of the episode. Some scenes were filmed in and outside of a Russian Foxtrot class submarine. "Small Victories" was nominated for Best Special Effects in 2001 for an Emmy, a Gemini Award and a Leo Award. Plot Confident that the destruction of Thor's starship has ended the Replicator threat to Earth ("Nemesis"), the SG-1 team returns home through the second Stargate that has been put up at Stargate Command. Shortly after they learn that a Russian Foxtrot class submarine has been hijacked by creatures whose descriptions match the Replicators, Thor arrives at Stargate Command and asks SG-1 for help against the Replicators in the Asgard galaxy. As Colonel O'Neill (Richard Dean Anderson), Daniel Jackson (Michael Shanks) and Teal'c (Christopher Judge) go to deal with the hijacked submarine, Major Carter (Amanda Tapping) goes with Thor. O'Neill, Daniel, and Teal'c try to obtain intelligence on the little self-replicating robotic invaders in the submarine, but they are forced to fall back. With Daniel's new theory that the Replicators are made up of the same materials they consume, the Replicators may be eliminated through sinking the iron submarine as long as the surviving Replicator from Thor's advanced ship is destroyed beforehand. Meanwhile, Carter witnesses a short battle against the Replicators in the Asgard galaxy during which five Asgard ships are lost. Carter notices the Replicators' attraction to new technology and proposes to use the O'Neill, an incomplete Asgard ship originally designed to fight the Replicators, as a lure to draw the Replicators into hyperspace and destroy them in the O'Neill's self-destruct. Thor eventually accepts the plan, the Replicators take the bait and are destroyed. Back on Earth, O'Neill and Teal'c penetrate the submarine and find and destroy the original Replicator. When the other Replicators take full control of the submarine, O'Neill
