That war had been won on another front, at Organia. But Suvuk, even after being physically tortured, and then subjected to the Klingon mind-sifter, had still, in rapid succession, broken free of his captors on the Klingon flagship Hakask at Regulus; disabled the ship's warp-drive and melted down its impulse engines, strewing unconscious, injured, and occasionally dead Klingons liberally along the way as he went; made solid-logic copies of everything of interest in the Klingons' library computers, then dumped the computers themselves; and had finally made it back aboard the newly-built Intrepid in a stolen Klingon shuttlecraft, well before the Organians' ban fell and both Klingons and Federation suddenly found their weapons too hot to handle.
