Battle of Luzon
As they arrived relatively late in the war, "Gilliam"-class ships did not get much chance to see combat. Some of the earlier vessels saw action at either the Battle of Luzon or the Battle of Iwo Jima and later at the Invasion of Okinawa, while later vessels saw combat either at Okinawa alone or not at all. Regardless, all of them spent a considerable part of their time on troop transport, cargo and other support missions.
