REASON FOR LOSS:
On the morning of the 25th December 1943, 1st Lt. Cox took off from Munda Airfield in P-38H 42-66892 on a Squadron mission to escort B-24s on a bombing mission at Rabaul in New Britain.
The loss of P-38H 42-66892 and 1st Lt. Cox was described by two eye witnesses:
‘Capt. George W. Phillips, the Intelligence Officer at Munde Fighter Alert Hut, reported at 12:10 December 25, 1943 1st Lt. Cox was flying with Capt. Smith and Lt. Green. Both Pilots observed Lt. Cox was last seen going down after ‘Zeke’ [Mitsubishi A6M ‘Zero’] from about 10,000 ft. at which point Lt. Green pulled up to rejoin formation. No one saw Lt. Cox crash’.
Capt. Grant R. Smith O-727567, DFC (Oak Leaf Cluster), Air Medal (11 Oak Leaf Clusters) and 1st Lt. William F. Green O-794322, Air Medal (11 Oak Leaf Clusters) survived the war.
1st Lt. Cox and his P-38H were last seen off the Duke of York Islands, NE of Rabaul in New Britain.

After the Japanese were defeated on New Britain it was found that there were only eight (8) surviving Allied PoWs at the Tunnel Hill PoW camp whereas it was expected to find a great many more. An investigation was instigated by the 18th Australian War Graves Unit to determine the fate of the PoWs that were thought to have been held on New Britain.
The investigation found that 1st Lt. Cox had baled out and was captured by the Japanese. He was initially held at the PoW camp at Rabaul. He was amongst the approximately fifty-four (54) PoWs who were moved from Rabaul to the Tanoura Mountain pass by truck. Surviving PoWs last saw 1st Lt. Cox on the 4th/5th March 1944 and he was in fair health.
It was claimed by the Japanese that 1st Lt. Cox was amongst thirty-one (31) PoWs who were killed in an Allied air-raid on the 4th/5th March 1944. However, after interrogating Japanese officers and soldiers stationed at Rabaul during the war the investigation came to the conclusion that this claim was not credible and that the PoWs had been executed.
An overview of the investigation into the circumstances of the deaths and those deemed to be responsible for the executions and atrocities is summarised in the report entitled “Talili Bay Massacre, New Britain”.
