Battle of Ragnar Anchorage
the breakout from the blockade
The Battle of Ragnar Anchorage was an engagement between Colonial and Cylon forces during the Fall of the Twelve Colonies. It came as Galactica re-armed at the anchorage and gathered the first survivors of the Fall, then held off the Cylon basestars while the civilian fleet escaped.
The Battle of Ragnar Anchorage was an engagement between Colonial and Cylon forces during the Fall of the Twelve Colonies. It unfolded at the Ragnar Anchorage, the military surplus depot where the battlestar Galactica had gone to re-arm and where the first refugees of the Fall had gathered before the survivors abandoned the Colonies.

Background#
The successful penetration of the Command Navigation Program allowed Cylon forces to introduce computer viruses into the warships and craft of the Colonial Fleet that relied upon it. Having only recently been decommissioned, Galactica was unarmed and unable to assist the main fleet under Admiral Nagala, which was swiftly destroyed for the same reasons that had crippled the rest of the fleet.

With Commander Adama assuming command over what remained of the Colonial Fleet, all surviving colonial forces were ordered to rendezvous at Ragnar, where Galactica was to re-arm from the Ragnar Anchorage military surplus facility. While docked, the battlestar was approached by a civilian refugee fleet led by the constitutionally appointed President Laura Roslin. The two leaders agreed that, in the absence of surviving warships capable of mounting a defense, they would abandon the Colonies' home star system entirely and head away, never to return.

The blockade#
As the survivors prepared to flee, the gathered ships were blockaded by two Cylon basestars. Kara Thrace found them, with hundreds of Raiders, waiting outside the radiation of Ragnar's atmosphere, which interfered with both FTL calculations and Cylon systems, so the fleet had to leave its cover to jump. Galactica went out first and shielded the civilian ships while its Vipers fought the Raiders, and a third basestar joined the attack. Once the last civilian ship was clear and the Vipers were back aboard, Galactica jumped away. The battle is the climax of the 2003 miniseries that launched the show. (Battlestar Galactica miniseries)
