During the Korean War, New Zealand and American fire support units
co-operated together on many occasions, but none was more important than
the Battle of Kap'yong in late April 1951. Toiling Kiwi and Yank gunners
helped stem the Chinese tide which threatened to engulf the UN
positions.
The Chinese Fifth Phase Offensive, which began on 22 April, was
designed to drive the UN Command into the sea. Between Hwach'on and
Kaesong, some 270,000 Chinese troops were set in motion, their immediate
objective to annihilate specific UN units and open up a decisive breach
in the front. Other troops held back to the north would then be thrown
in to complete the defeat of the UN Command.
Kap'yong, located at the mouth of a narrow valley leading north of
the 38th Parallel, was well to the south of the front line on 22 April.
The Commonwealth 27 Brigade had gone into reserve in its vicinity a few
days before, while the South Korean 6 Division continued the advance
into North Korea. The New Zealand 16 Field Regiment had remained up the
valley to provide support until it found itself unable to keep within
range of the infantry, as the road petered out in the mountainous
reaches.
This regiment had been raised in New Zealand in 1950 following the
government's decision to contribute a ground force to the UN Command.
When volunteers had been called for, five men had come forward for every
place available. The gunners had entered camp on 29 August, and spent
next three months being trained, before leaving Wellington on 10
December. They reached Pusan on 31 December and joined 27 Brigade on 22
January 1951. A few days later their twenty-four 25-pounders were in
action. During the next three months practice had greatly improved their
capacity to support the infantry.
When the Chinese offensive broke the New Zealanders were already
under orders to return down the valley to 27 Brigade near Kap'yong. The
events at the front ensured that this move took place during the night,
some hours earlier than intended. But next morning the IX Corps
artillery commander ordered the regiment back up the valley to support
the South Koreans, who were supposed to be making a stand after falling
back a considerable distance in some disarray.
To provide additional support, the American 213 AFA Battalion, with
its eighteen 105-mm self-propelled howitzers, was redeployed from the
Hwach'on area. A National Guard battalion which had also been raised in
the United States about the same time as the New Zealand regiment, it
had enjoyed a much longer period of training and acclimatisation than
had the New Zealanders, only reaching the front in April. It had fired
its first shot in anger on 22 April. On the 23rd it returned to
positions at Sindang-ni, on a tributary of the Kap'yong river, which it
had occupied until being sent to Hwach'on three days before.
While it was hoped that the South Koreans would hold their positions
up the valley, precautions were taken in case they did not. This
entailed deploying 27 Brigade at the mouth of the valley, with a
Canadian battalion and an Australian battalion occupying dominating
hills on left and right respectively. The brigade's other battalion, the
British Middlesex Regiment, had been sent up the valley to provide close
protection for the New Zealand gunners. Both Canadian and Australian
battalions had a company of the 2nd Chemical Mortar Battalion in
support, Co A with the former, Co B with the latter. These companies had
been attached to 27 Brigade for some weeks before this crisis.
These precautions were timely, for it became evident during the
evening that the South Korean division had virtually disintegrated.
Panic-stricken Koreans made their way down the valley. The New Zealand
and American gunners both experienced a hair raising withdrawal behind
the Commonwealth infantry, the American regiment losing one of its
pieces when a road gave way. The New Zealanders carried out the
Middlesex infantrymen on their vehicles and guns.
When the Chinese assault began on the Australians around midnight,
there were six batteries of artillery and Company B's mortars within
range, but coordination was lacking mainly because of poor
communications. There is evidence that the New Zealanders fired
defensive support missions for 3RAR's B Company, and also that the
mortars were in action, though Australian veterans nowadays tend to
discount this support. The Australian A Company was heavily assaulted,
but held its ground. During this period the New Zealand forward
observation officer with this company was killed and his party separated
from their radio, effectively ending any chance of co-ordinated
defensive support from the New Zealand guns.
Meanwhile other Chinese troops had circled round to attack 3RAR's
battalion headquarters. This was a dangerous development, and the New
Zealand and American gunners were preoccupied with dealing with this
threat until they, too, were troubled by Chinese infiltrators. Around 2
am the decision was taken to withdraw the artillery units to safer
positions to the south. Both regiments pulled two of their batteries
back immediately, leaving the other as a rearguard. These latter
followed as day was breaking. At this point the Australian headquarters
was overrun. The Mortar Battalion's Company B also tried to withdraw but
was halted and, leaving their vehicles, retreated through the hills, as
did a Middlesex company. Company A, 800 yards to the west, was forced to
withdraw at about 6 am, losing three of its mortars. (The withdrawal of
Company B has been unfairly misrepresented in Australian histories as
taking place about midnight, and even the US official history of Army
operations in Korea has followed this line.)
With daybreak on the 24th, the artillery support became more
effective as co-ordination improved. The New Zealand regiment controlled
the fire from both it and 213 AFA Battalion. A battery of 17 FA
Battalion's 8-inch howitzers was on call from early afternoon, and 61 FA
Battalion (105-mm howitzers) became available in the evening. New
Zealand officers with radios sets were sent to the American batteries to
facilitate the transmission of fire orders. This fire power was vital
during the afternoon of 24 April as the Australian battalion's infantry
companies were successfully extricated from the virtually surrounded
position they found themselves in. Gunfire not only obscured the
withdrawal from the enemy but also later prevented them from closing
with the retreating troops.
During the night of 24-25 April the Chinese turned their attention to
the Canadian battalion. The attacks were pressed home with great
determination, and at one stage the Canadians were forced to call down
fire on their own positions. But the massive artillery resources now
available ensured the battalion's survival, though it too was virtually
surrounded. Next morning, however, the Chinese were found to have pulled
back.
The Commonwealth troops, now reinforced by two battalions of the 5
Cavalry Regiment, were ordered to advance during the afternoon of the
25th. The former Australian positions were reoccupied, but developments
elsewhere led to them soon being abandoned as the whole of IX Corps was
ordered to pull back to positions on the Han River. The New Zealand and
American gunners covered the withdrawal of the infantry battalions.
The successful blunting of the Chinese offensive in the Kap'yong
sector was a combined effort of British, Australian, Canadian, New
Zealand and American infantry, tankmen, mortarmen and gunners. Both the
Canadians and Australians, as well as Company A, 72 US Tank Battalion,
received US Presidential Citations for their efforts during the battle.
The New Zealanders had to be content with the South Korean Presidential
Citation, the differentiation reflecting the tendency to down play the
importance of the artillery in halting the Chinese. Indeed, in
Australian accounts of the battle 213 AFA Battalion does not even rate a
mention.
