The Fugitive Fleet

The fleet collected by Galactica in the wake of Cymtar and the destruction of the Twelve Colonies was initially assembled from civilian ships, many of which were available only because they had been mothballed and slated for the scrap yards. Other, more modern ships, had survived the Cylon attack by fleeing, and returning later, or simply because the Cylons were too busy seeking military targets to bother with them. Only after the Cylons were confident that the Colonial Military was all but destroyed, did they turn their attention to hunting down civilian craft.
During the first three to four yahrens after the formation of the Fugitive Fleet, civilian and even surviving military vessels, continued to seek out and join the Fleet. Various warships, shepherding small flotillas of civilians, having made their way via circuitous routes from what was then Cylon controlled space, to join the main Fleet, would catch up and add their numbers, resources and much needed firepower. Sometimes the newcomers were solo ships who had fled the disaster and lurked along the edges of known space until whisper of the surviving Battlestar and its growing fleet drew them in.
The composition of the Fugitive Fleet today is as follows.
