Colonel Warburton was a British military officer.

Baron Maupertuis convinced him to lead the invasion of Ry'leh to help expand the British Empire. After arriving on the planet, though, he was surprised and frustrated by the Shlangii's resistance which was greater than he had been led to believe. He argued with Maupertuis, blaming him for the misinformation. Enraged at the Colonel's failure to defeat the natives, Maupertuis killed Warburton. (PROSE: All-Consuming Fire)
