The Battle of Antarctica took place in Antarctica even though the Goa'uld never considered earth a threat the Goa'uld System Lord Anubis decided to launch an all out full offensive against the planet. Bringing with him 30 Hataks earths defense earths only defense was The Prometheus 17 F-302 fighters and supposedly the lost city which was thought to be under the ice.

This battle took place in the massive Void between the Milky way and Pegasus galaxies. After their brief alliance with the Wraith the Atlantis expedition was double-crossed as the Wraith only wanted to figure out where earth was. Once they did they sent two hive ships. Because of the limits with Wraith technology on their way to earth they had to stop to regenerate their ships hulls. unbeknowest to them The Atlantis Expedition sent the Daedalus and the Orion to intercept them.

 The Battle of Dakara was a massive battle that was Fought from three different sides The Goa'uld, the Jaffa rebellion and The replicators. With the replicator invasion of the milky way galaxy the Goa'uld system lords quickly fell absorbing their fleets into his own Ba'al had enough ships to go on the full offensive.
With the system lords falling at the hands of the replicators Teal'c used this example to show the Jaffa that the Goa'uld were not gods. The Jaffa rebellion was born. To completely shatter the remaining Jaffas beliefs the Rebellion took the planet Dakara. Ba'al was ordered by Anubis to take it back to keep the Dakara Superweapon under his control.
Ba'al fearing or his life told Jack o'Neill about the plan to take Dakara, Jack O'Neill pasted it on to Dr Daniel Jackson who after getting his mind Probed by Replicator Carter inadvertently told the replicators about the plan. Knowing the Threat the Dakara Superweapon posed Replicator Carter dispatched an entire fleet to the planet.

This Battle was the first engagement fought between the forces of the Milky Way galaxy and the Ori. Because the distance between the Ori Galaxy and the Milky Way was so great only a Stargate could be used to traverse the distance. Thus the Ori began work on a Supergate, a stargate so big it would allow ships to go though. Now the Milky way had a real problem on its hands as ever since the Ori came into contact with humans in the Milky Way they've been building ships in which to forcibly covert the whole galaxy. After attempts to stop the ori from Dialing in (buy Dialing out) failed a fleet consisting of Lucian Alliance, and Free jaffa Hataks, Two Daedalus Class warships and an Asguard Vessel went to the supergate confront this new threat. Words cannot describe the devastation the Ori caused.

OK long story short the Ori converted this planet with a group of human called the Rand Protectorate. Because they were now twisted into the believing the Book of Origin they decided to use an Ori Weapon Satellite to attack another group called the Caledonian Federation. Daniel Jackson along with Jared Kane was sent there to find a diplomatic solution, the Prometheus was also sent just in case the the diplomatic solution didn't work as the satellite was deemed to much of a threat. Once there Daniel Jackson and Jared Kane were captured immediately. The Prometheus crew had no choice but to destroy the weapon. Little did they know the power of this weapons satellite but it was already to late.

This battle took place simply because the blueberry Aliens Wanted Destiny. For years they have been trying to get their hands on it but to no avail. That's it no subtle story no hidden agendas. Exactly why they want destiny in the first place is unclear.
