Battle of the Black Hole

The Battle of the Black Hole occurred in 2006 during the Ori crusade and Tau'ri-Wraith war.

Prelude
After the Battle of P3Y-229, the Ori were free to come into the Milky Way galaxy as they pleased. In an effort to stop them from sending any more ships into the Milky Way galaxy, a plan was devised by the Tau'ri, which led them to the Pegasus galaxy.

The Battle
The Odyssey orbited a black hole in the Pegasus galaxy in order to connect a wormhole to the Supergate in the Milky Way galaxy using a jump between a Pegasus Stargate and a Milky Way Stargate using nuclear warheads. The attempts mostly failed, but the nuclear detonations drew a Wraith Hive Ship to the Odyssey's position.

The hive ship engaged the Odyssey in battle and caused the Odyssey's' hyperdrive to go down. The Odyssey was at a disadvantage due to the black hole interfering with its systems and the gravity well as well, so the Odyssey drew the hive ship in closer while pulling a sling-shot maneuver. The hive ship's systems, including its jamming field, were effected by the black hole and Odyssey beamed the last two nukes on board when its next to the active Stargate. The hive ship was destroyed and the blast caused the wormhole to jump to the Supergate on the other end, destroying an Ori mothership that was over the Supergate at the time.

Aftermath
The Odyssey soon returned back to the Milky Way galaxy. Even though the Ori were unable to send more ships through the Supergate, for the time being, the remaining three still caused massive problems. The Supergate remained unusable to the Ori until early 2007 when, the semi Ori converted, Daniel Jackson re-dialled the gate and sent the Sangraal through. Despite killing the Ascended Ori, the Ori followers still sent another wave of ships into the galaxy.
