I tried to route information via another channel, but since I can't find it now, I will send this as replacement.
The SS HARTLEBURY was a part of one of the great sea tragedies of all time.
It sailed as apart of a 36 ship convey (PQ-17) from Iceland, bound for a northern port of Russia, by way of England. A total of 33 ships broke port there, enroute to deliver war materials to combatants in Russia.
The combined tonnage was approximately 156,000 tons, enough to arm 50,000 men and women. Its estimated value was a whopping 700 million dollars.
Nazi U-Boats and the Luftwaffa sank 24 of the 33 ships outright, the SS HARTLEBURY, included, with all hands.
The ship carried right at 56 tons of materials, and was hit and sank at 8:00 PM, 7 July 1942, by the U-355.
I will try to bring you information on your grandfather's ships later. OK ?

NEWCASTLE... Emlyn, Wales -on-Tyne -under-Lyme ???
I spent a couple of nights at N-on-Tyne back in the late '70s, where I engaged an elderly man, who told me of the excitement one night when a German dirigible(WW I, obviously) dropped its bombs there, without causing any damage, just excitement.
