On 1 June 1944 this officer was leading his platoon on patrol along
a narrow ridge path just north of the Kyusanlai Pass, following up a
Jap phone cable, when the tops of Jap bivouacs were seen just ahead
on a steep knoll on the ridge. Lieut. ARNOLD quietly deployed his
sections to right and left to stalk the position from the flanks
When this movement had developed sufficiently, he himself continued
straight up the path with 2 or 3 men until within 5 yards of a Jap
automatic covering the path. The enemy were not keeping a good
lookout and could be seen sitting about. Lieut. Arnold then gave the
signal for the assault by shooting three of the gun numbers in
succession before a fourth sprang up out of the trench unseen and
fired the automatic. The sections closed to within a few yards of
the enemy and shot and grenaded many before they were fully aroused.
However, owing to the steep going and thick undergrowth the attack
could not be pressed home. The enemy showered grenades down the
slopes and brought 4 automatics to bear. Lieut. ARNOLD accordingly
withdrew fighting off a Jap section which had been following him up
behind. He then bombarded the position with observed rifle grenade
fire. Enemy casualties were estimated at 14 killed and as many
wounded and our own casualties were one killed and one wounded.
The next morning touch was regained with the enemy who had moved out
of his post and an inconclusive engagement followed at close
quarters from which the enemy withdrew. On following up, the enemy
defended position was found to be evacuated under cover of the
morning's engagement. It is clear that the rough handling he had
received the day before caused the enemy to evacuate a key position
on the main ridge close to the pass and overlooking Nammun and from
which it would have been exceeding difficult to eject him.
On a previous occasion at Mawlu on 18 April '44, this Officer
distinguished himself by his daring and inspiring leadership in a
very nasty mopping up operation when he personally came to grips
with an automatic in a somewhat similar manner as on this occasion.
