When the 10000 plus Army personnel arrived in January 1944, they caused considerable aggravation amongst the indigenous population, still remembered today. Lt General Mugikura removed the chief and his family from his home in Roro and established it as his headquarters. A nearby field was established as a park for playing baseball. A large bunker was dug to form an extensive shelter during the bombing.

Roro was also the location of the main water supply (from streams) on Tonoas and the Japanese dams are still in use today. - NPS
