The Driniumor River runs roughly south to north,
emptying into the sea. Located to the east of Aitape and
17 miles east of Tadji. During late April 1944, the west shore of the river was
the American perimeter around Aitape,
encompassing Aitape Harbor and Tadji Airfield.
After the US Army landed at Aitape on April 22, 1944, a covering force comprising the US Army 32nd Infantry Division and 112th Cavalry Regiment was sent eastward to guard Aitape's eastern flank on the Driniumor River. Only minor actions took place up to July 1944, as the US garrison
was reinforced and built defensive positions along the Driniumor
River to meet an expected Japanese attack.
Japanese Counter Attack
This came in July 9-10, 1944 beginning
with an attack of the Japanese Army's 128th Infantry Regiment,
32nd Infantry Division. By July 11, over 800 Japanese troops
were killed, but they were able to penetrate the line at one
area, and for US troops to withdraw.
Japanese also attempted to flank south of the American positions
by moving inland to Afua in the Torricelli Mountains where fighting
raged for two weeks, and was often hand to hand but they failed
to break the line.
In mid-July and the US troops were forced to withdraw. During the fighting along the Driniumor River the 31st Infantry
Division's 124th Infantry Regiment killed more than 3,000 of the
enemy and played a major part in breaking the back of the by-passed
Japanese 18th Army. However, repeated counterattacks restored
the position and the Japanese sustained heavy casualties. In
further attacks in August the Japanese around Aitape
were thoroughly defeated, and the scattered remnants fled back to
the east and south to join Japanese forces between the
mouth of the Sepik River and Wewak.

Relief By Australians
Repeated US counterattacks restored the original line,
and the Japanese sustained heavy casualties, with the final Japanese
attack came on August 4, with 200 attacking and were massacred
on the American line. The Americans in the Driniumor River area
by the Australian 2/4th Battalion at the end of November 1944.
Eugene Salternik, 25th Liaison Squadron (L-5s) recalls:
"I flew an officer over the battlefield and landed nearby so he
could survey the area. I snapped a photo of the area from my
L-5, you could see stacks of bodies from the air, it was a massacre."
