1200 Hours, 14 December 1942, HMS Victorious, Reykjavik, Iceland – Vice Admiral Lyster was hosting Rear Admiral McWhorter, senior flying officers, and carrier captains onboard HMS Victorious for one last planning session. The task force was due to sortie in 24 hours, coincident with the sailing of the Murmansk bound convoy JW-51A from Loch Ewe, Scotland. Despite the security surrounding the operation, Lyster assumed the Germans would pick something up and his scheme of maneuver was designed to disguise his task force’s movements as that of a heavy covering force for the convoy.
Training of the strike squadrons against the task force’s battleships over the past week had not gone as well as the senior officers had hoped it would. They had lost three days of practice due to poor flying weather and the training sorties had cost six aircraft. The Americans lost a Wildcat and two SBDs and the British lost a single Albacore and two of the new Barracudas. Four valuable air crews were lost to the frigid water as well. The accidents could not be helped, the mission demanded realistic training and realistic training always led to losses. The weather forecasters were predicting several days of relatively clear weather and Lyster and McWhorter would have preferred two or three more days of training but the phases of the moon, predicted weather over the target area, and convoy sailing schedules meant the task force sailed on 15 December, ready or not. After an early dinner Lyster dismissed his guests to make final preparations and to get some rest. The next five days promised to be interesting.
