The Battle of Hill 239 was an engagement between the Victorian Independent State and the United Nations Space Command during the latter's attack on Victoria in 2553. During the early stages of the landings, the UNSC Navy dropped units of the 19th Shock Troops Battalion on top of a hill outside Agley. The rebels, who had spotted the fiery trails left by the battalion's SOEIV pods, prepared for combat. Oliver Graham, the rebel commander, had his troops wait until the ODST's had clustered together and began preparing to fortify the area to attack, driving the troopers off the hill.
