September was a grim month for the Australian Beauforts.  The job demanded of them was one which necessitated grave risks.  Gasmata had to be kept unserviceable to prevent Japanese fighters from interfering with Allied moves in the Lae area.  On September 4, the Beauforts struck at the Gasmata airstrip.  Once again they were met by fierce anti-aircraft fire.  A9-204 was shot down and crashed in flames.  Its crew was Flying Officer Tom Allanson, Flying Officer Mervyn Keehn, Flight Sergeant Keith Grieve, and Flight Sergeant Dennis Webb.

At 0547 hours on 4 September 1943 Beaufort A9-204 took off from Gurney Strip to carry out a bombing attack on Gasmata, New Britain. The attack was carried out ay 0750 hours from an altitude of 1,500 feet. When over the Gasmata strip A9-204 was hit by anti-aircraft fire, was seen to be smoking and immediately went into a vertical dive, crashed and burst into flames. No crew members were seen to bale out and eye witnesses reported that there would have been no chance of any survivors.

In 1948 a RAAF search party located the wreckage of A9-204.  It had crashed in mangrove swamp on the coast of New Britain about 3 miles north east of Gasmata.  A thorough search could not locate the remains of any of the crew. The aircraft which was completely wrecked exploded on impact and all the crew would have been killed instantly.

The crew members of A9-204 were:

Flying Officer Thomas Hessey Allanson (415106) (Pilot)
Flight Sergeant Keith Grieve (405850) (Wireless Air Gunner)
Flying Officer Mervyn Noel Keehn (405193) (Navigator Bomb Aimer)
Flight Sergeant Dennis Hamlin Webb (405458) (Wireless Air Gunner)
