aid of tanks and support weapons they were 
able to reduce the fortifications one by one. 
By the end of the third day, there remained only 
two areas still in Japanese hands; the biggest 
and most formidable being in the northeast 
centered on Romauldo Hill, a series of coral 
ridges and outcrops even more rugged than, but 
not as large as, on Peleliu. With the situation 
reportedly well in hand on Peleliu and 
Angaur, the IIIAC Reserve, the 8ist Infantry 
Division's third RCT, the 323rd, was sent on 
to its secondary target of Ulithi Island as 
planned which was easily seized as it had 
already been abandoned. 
In fact it would take another four weeks of 
bitter hand-to-hand fighting before Major Goto 
and his men, well armed with rifles, machine 
guns, and mortars, and dug well into the 
mass of caves and tunnels in the Romauldo 
Hills, were crushed, and then only with the 
extensive use of flamethrowers, grenades, and 
demolitions alongside the sheer determination 
of the Wildcats. October 22 marked the end of 
formal Japanese resistance. Casualties for the 
81st were comparatively light compared to 
those on Peleliu; 260 killed, 1,354 wounded, 
and 940 incapacitated for non-combat 
reasons. The Japanese lost an estimated 
1,338 killed and 59 taken prisoner. 
"A HORRIBLE PLACE" 
The 81st Infantry Division's 321st RCT began 
arriving from Angaur on September 23 and 
began to relieve Puller's battered 1st Marines 
who were initially withdrawn to the south of the 
island to rest. They attacked the northeastern 
peninsula on D+11. These had been dubbed 
Hills 1,2, and 3, and Radar Hill, known as "Hill 
Row," and were actually the southern arm of 
the Amiangal Ridge. They were defended by 
some 1,500 infantrymen, artillerymen, and 
naval construction troops plus reinforcements 
from Koror. As the right progressed the 2nd 
Battalion, 5th Marines side-stepped to the west 
and pushed on to the north, leaving the 1st 
Battalion to continue the assault, and by 
nightfall had taken the southern end of the final 
ridge. What the 2nd did not know was that they 
were facing the most comprehensive cave 
system on Peleliu which was the underground 
home of the Japanese naval construction units 
who were, luckily for the Marines, better miners 
than infantrymen. 
Fighting continued all day D+11 and D+12 
with several small-scale counterattacks during 
the night but by the end of D+12 the 2nd Battalion 
had secured the northern shore (Akarakoro 
Point) though if the Marines held the area above 
ground, the Japanese still held it underground! 
It would take weeks for the Marines to finally 
quash all resistance on Akarakoro Point, and 
then only by blasting closed all the tunnel 
entrances, sealing the Japanese defenders inside 
to their fate. After two days of bitter fighting the 
Marines blasted and burned their way to the tops 
of Hill Row and by D+14 all but the Umurbrogol 
Pocket had been taken. 
THE POCKET 
The assault on the Japanese defenses in the 
Umurbrogol Pocket now took on the air of a 
medieval siege. With the attacks from the 
north by the 321st RCT the encirclement of the 
Pocket was complete whilst the 7th Marines 
continued to press from the south and west. 
The Pocket was now down to 1,000 yards by 
500 yards in size, not much bigger than ten 
football fields. 
Major-General Rupertus then made a less 
than sound decision by ordering the 1st Tank 
Battalion to return to Pavuvu. Their heavy 
firepower would be sorely missed in the final
