Jacob Jiles

Governor Jacob Jiles was the leader of the base of Eridanus Secundus. He replaced Colonel Robert Watts as leader of the Eridanus Rebels after the former was captured by the Spartans in 2525. His background is unknown, but the black haired rebel was a slippery man, who worked only to serve himself. His tactics kept his people safe, as neither the Covenant nor the UNSC could locate or put a stop to his operation.

In 2552 he assisted the Gettysburg-Ascendant Justice hybrid vessel in making repairs before they would return to Earth. He had been blackmailed by Admiral Whitcomb, who brought the vessel to Eridanus Secundus knowing the Covenant would track them and locate the asteroid. Jiles did all he could to help repair the vessels before the Covenant attacked. The humans were able to hold off one cruiser, but when 30 arrived, there was no way to win and survive if Whitcomb had stayed. Unfortunately the Covenant attacked before then. Governor Jiles is assumed killed when the vessel was forced to retreat from the area.

He had a personal ship, a former ONI prowler called the Beatrice that was stolen by Dr. Catherine Halsey.
