Battle at Pahvo

The Battle at Pahvo was a battle fought between the United Federation of Planets and the Klingon Empire in 2256, after the Pahvans initiated contact with a Federation away team. The Pahvans wanted to help both sides find harmony, and sent an invitation to the Empire, which was detected by Kol. Kol then took the Sarcophagus to the planet, initiating a standoff with the USS Discovery (NCC-1031). (Star Trek DIS episode: "Si Vis Pacem, Para Bellum")

The battle started after the crew of the Discovery found a way to penetrate the Klingon's cloaking device by generating an algorithm using data sent back by two transmitters placed on the Klingon ship by an away team. Lieutenant Paul Stamets was able to utilize the Spore drive to keep the Klingons on their feet, while Discovery's computer generated the algorithm. Kol, confused by what he was seeing, ordered the Sarcophagus to cloak in order to defend from the Discovery's jumps. Unfortunately, this played right into their hands, allowing the Federation ship to complete its task. After penetrating the cloak, Discovery pulled its away team off, and fired it's torpedoes at the Sarcophagus, destroying it and its crew. As Michael Burnham was being transported off, L'Rell grab hold of her, and escaped the ship moments before its destruction. (Star Trek DIS episode: "Into the Forest I Go")
