Beaufighter UB-G of RAAF 455 Sqn against 6 FW190s 7/4/1945

Could anyone help in identifying the luftwaffe Group involved in a running battle with the beaufighter of RAAF Squadron 455 that had attacked a ship in a Fjord not far from Bergen. The beaufighter eventually escaped to crashland back at its base, Dallachy in Scotland. The crew is alive and well in Queensland Australia today. The navigator scored hits on a FW190 (probably an A model with radial engine which broke off the attack). Don Mitchell (navigator) and Ian Murray (pilot) would be grateful of any assistance.

Dallachy Strike Wing attacked and sank "Oldenburg" at Vadheim, Sogn og Fjordane on this date. The Strike Wing was attacked by Fw 190's based at Herdla. They belonged to 9th Staffel. III. JG 5. Two of the Fw 190's were shot down. A Mustang of 19 Sqdn. also failed to return.

Thanks ever for that reply flyvrak,
couldnt believe that it would happen so fast!
To make it even tougher could you detail the FW190 losses (who shot them down) and also if members of 9th staffel can be contacted .
Realise that probably too tough.
Also if you want any detail on these 455 crew can oblige.
