15 September 1942

Australians now holding Ioribaiwa for fifth day as Jap numbers build up and they redouble their efforts to find the Diggers' flanks and try their normal tactic of encircling them.

The invaders added mortars and heavy machine guns to their mountain artiller piece and the Australians suffer significant casualies. The 2/14th Battalion's HQ comes under consistent fire and the unit loses seven dead and 19 wounded, with an additional 17 evacuated due to illness.

Australian patrolling keeps Japs off balance and denies them access to the Australian flanks.
