http://en.wikipedia.org/wiki/Y_Gododdin - to cut long story short, it's an early welsh poem ascribed to Aneurin, taking the form of burial elegies for 300 cavalrymen from southern Scotland who took on a much larger force of Anglo-Saxons and were beaten catastrophically. Most of the poem is lost so only 82 of the warriors are named. Also there's a great deal of argument about the translation. I'm filling in some gaps with Dark Ages heroism, handsome warriors, brave steeds, blood, gore, plentiful angst and a leavening of humour. It's a bit like "300" only with more clothes and no elephants. :) It's fun when I'm not worrying about my word count.
