Received from Rob Martin - His source: "Nightmare Convoy" by Lund and Ludlam (1987), which gives 22 ships.

Further details have been added with the help of:
"The Allied Convoy System" Arnold Hague
"Axis Submarine Successes of WW II", Jürgen Rohwer
"The World's Merchant Fleets", R. W. Jordan.
"Lloyd's War Losses" Vol I

Plus 3 more unnamed ships, 1 of which was Greek, the others British.

The convoy was attacked on Aug. 18 by 2 Ju 88's, but no damage.

As will be seen from what follows, numbers of casualties and survivors from each ship varies according to source - I've quoted some of them (a few of the ships mentioned here are not listed in R. W. Jordan's "The World's Merchant Fleets").

Aug. 19 - Nightime attack by U boats (all times are German times):
At 02:05, the straggling Norwegian destroyer Bath was sunk by U-204 - I have a crew list on this page.
"Nightmare Convoy" says she had a crew of 130, 83 lost (13 RN), and about 50 survivors).

At 02:08, Alva was torpedoed by U-559.
• "Nightmare Convoy" states she had a crew of 25, 24 survivors - 17 later lost with Clonlara and Empire Oak.
• "The Allied Convoy System", Arnold Hague, says she had 16 casualties, 9 of whom died with Empire Oak.
• R. W. Jordan gives U-201 as the attacker, 1 died, 24 picked up by Clonlara, 15 died when the latter was sunk.
• "Lloyd's War Losses" says she had a crew of 25, including 4 gunners. 1 crew died when Alva was torpedoed, remainder picked up by Clonlara, 15 died when the latter was sunk, including 4 gunners - 16 casualties in all.
• Uboat. net says that all 25 survived the initial attack, and that 11 Alva survivors picked up by Empire Oak survived the attack on the latter, but 14 died when Clonlara was sunk.

At 04:06, Ciscar was torpedoed by U-201.
• "Nightmare Convoy" gives 38 crew, 15 survivors.
• Arnold Hague gives 18 casualties.
• R. W. Jordan gives U-204 as the culprit, 13 died, 26 survived, 5 survivors on Cervantes, 2 of whom died when Cervantes was sunk - Cervantes was sunk the following month, when en route to Liverpool in Convoy HG 73.
• R. W. Jordan appears to have gotten some of his information from "Lloyd's War Losses", which says Ciscar had a crew of 30 and 9 gunners, 21 of the crew and 5 of the gunners were saved - 3 of 5 Ciscar survivors died when Cervantes was was sunk the following month. Checking the information for Cervantes in this source, I found that it lists 4 passengers, 3 of whom (Ciscar crew members) died when she was sunk on Sept. 27, when en route to Liverpool. (For info, Empire Stream was also sunk in Convoy HG 73, as were Lapwing and Petrel - see this page on Uboat.net).
• Uboat.net says 13 died, 35 surv and were picked up by Petrel.

At the same time, Aguila was also torpedoed by U-201.
• "Nightmare Convoy" gives 161 passengers and crew, 16 survivors (six of whom were lost on the Empire Oak.
• Arnold Hague gives 91 passengers, 156 died in all.
• R. W. Jordans says 157 died, 10 survived.
• "Lloyd's War Losses" says she had a crew of 65 and 5 gunners, 58 crew and all 5 gunners lost, as well as the Commodore and his staff of 5, and 89 out of a total of 91 passengers.
• Uboat.net gives 152 dead, 89 of whom were passengers, and 16 survived (168 on board in all) - 6 later lost with Empire Oak (the other 10 had been picked up by HMS Wallflower).

On Aug. 22
Marklyn broke down and was unsuccessfully attacked by 2 Ju88's whilst rejoining convoy.
