Turin was a night trip. S/L Nettleton and crew were shot down by a German night-fighter.
Yeah - this is what gave me pause about that:

and here as The Focke-Wulf 190 With 5./B.F.Gr. 196, 1./S.A.Gr. 128 AND 10./Z.G. 1 in MSWord format:

Mr Arthy seems to have done a good job of research. Transcribed German microfilm records available on the net don't list any NJG claims for the night of 12/13 July 1943, as he says. There are plenty for 13/14 July on Bomber Command's trip to Aachen.
Several sources I've seen say Nettleton's aircraft was shot down by a nightfighter "off the Brest peninsula" but the Turin raid didn't go near Brest on the way in, when it was dark. The stream went directly to the target via Cayeux and Paris, well to the east. After bombing Turin the stream was routed westward over southern France, then well out over Biscay before turning NNE to Britain over the western Channel. The crews were warned to swing wide of Brest to avoid the defences.
There was insufficient darkness to cover the round trip to Turin. In July Brest gets 16 hours of daylight per day. Sunrise is about 5.30am. A descendant of one of the pilots killed on the raid, P/O Thomas Forbes of 12 Squadron, dug up the 1 Group orders for the (return) trip which end with: "(D) AFTER CROSSING THE ALPS A/C ARE TO LOSE HEIGHT AND FLY LOW OVER FRANCE. AFTER CROSSING THE ENEMY COAST A/C ARE TO FLY AS LOW AS POSSIBLE. AS SOON AS IT IS LIGHT ENOUGH A/C ARE TO ENDEVOUR TO COLLECT TOGETHER IN TWOS FOR MUTUAL SUPPORT." I gather the planners knew the aircraft would be coming home in daylight. Here's the link to the rest of the order, and some more raid route details:

German pilots claimed several four-engined aircraft off Brest and over the Channel about 6.30am, claims made by FW190 day fighters scrambled just after sunrise to intercept. JG2 claimed Lancasters while SAGr 128 claimed Liberator and Halifax aircraft - mistakenly, in Arthy's view.
Terrible weather there and back gave the Turin bombers some protection but the cloud also made it very tough to find airfields, so it appears the pilots had a hard choice to make: avoid Brest and have less fuel, or 'cut the corner' and risk the fighters to gain a safe margin for landing.
I'm inclined to believe Nettleton's was among the aircraft the FW190s claimed, although one bomber did report being attacked by a Ju88 over the channel.
