Took off at 12:40 hrs from Witchford near Ely in Cambridgeshire to attack Dortmund. 177 Lancasters took part in this G-H attack on the oil plant in Dortmund which had been classed as very accurate even though the raid took place with thick cloud.

G-H - A two station radio direction finder system - Instruments in the bomber measured its position from one station and distance from another. It could be used by up to 80 bombers from any one pair of stations. By using more than one pair of stations, multiple targets could be attacked at the same time without the aid of pathfinders and markers. Once a major part of Bomber Command was fitted with the technology, G-H became a most useful blind-bombing device.

Captured German documents record that the aircraft was shot down by flak at 15:40 hrs which crashed near the railway station at Kircherne, 3km NE of Dortmund.

Very unusual crew complement on Lancaster HK595 - normally a 7 man crew this Lancaster had a crew of 9 - made up with an extra Pilot and an extra Air Gunner who operated in the mid-under (belly) gunner position.
