The E-boats keep coming . . .
The war at sea in English waters in November 1942 was a slightly quieter one than October 1942 had been, and December 1942 would be. For all that the E-boats kept coming (S-boote in German).
On the evening of the 9th the 2nd, 4th and 6th S-boot Flottille, responsible for the loss of several ships of convoy FN 832 off Norfolk in October 1942, opened fire once more on another FN convoy, FN 861, again off the east coast.
According to Wehrmacht reports, 4 ships from a convoy were sunk, and three ships, two steamers and an escort, were reported damaged.  In fact, the only victim sunk on the 9th was the Norwegian steamer Fidelio, torpedoed east of Lowestoft. The steamer Wandle was badly damaged in the same attack, her bows virtually blown off but still partially attached and sinking. Somehow she was kept afloat, albeit awash, and ultimately she reached the Tyne for repair after several days under tow in fog and heavy seas. She would go on to be rebuilt and continue in service until 1959. 
On the 15th the British steamer Linwood, on convoy FS (Forth South) 959, struck a mine laid by air off the Long Sand Head in the approaches to the Thames, with the loss of three DEMS (Defence of Merchant Ships gunners). Elsewhere, in the North Sea and the Baltic, similar mines laid by British aircraft accounted for at least 7 ships during the month. 
In the early hours of the 19th the six ships of the 5th S-boot Flottille, S-68, S-77, S-82, S-112, S-115, and S-116 located convoy PW (Portsmouth-Wales) 250 off the Eddystone with the assistance of ‘Lichtenstein’ radar apparatus. Most sources state that the attack was carried out by the E-boats alone, but the Merchant Shipping Movement Cards for the three cargo vessels lost in this incident suggest that it was a coordinated E-boat and aircraft attack.  That said, there is no explicit mention of attack from the air in the evidence given by the Norwegian survivors of one of the ships on 21 November 1942 at Plymouth before the Norwegian vice-consul though there was a hint by the carpenter, Peder Andersen, that on his lookout he saw a ‘bright light shining down’.  The master, Emanuel Edwardsen, introduced his evidence in an understated fashion, stating that he was unable to produce the logbook due to circumstances which would become clear in his account. All the witnesses confirmed that they had felt the shock of not one, but two, successive torpedoes and they were unable to release one of the boats, but successfully got away in the other, to be picked up by a British vessel.
The victims were the former Danish Birgitte now sailing under the British flag, with the loss of 10 crew, the Norwegian Lab with the loss of 3 lives in the stern part of the ship, the British steamer Yewforest laden with steel billets, with 9 crew and 2 of her gunners, and their escort, HMT Ullswater, which was lost with all hands. The four wrecks lie in close proximity to one another and Ullswater is on the Schedule of Designated Vessels under the Protection of Military Remains Act 1986. 
Like many of her compatriots, the Danish Birgitte had come under the control of the Ministry of War Transport (MOWT), having been seized as a prize and requisitioned by the British authorities at Gibraltar in May 1940 after the fall of Denmark. Lab became one of the famed Nortraships (Norwegian Shipping and Trade Mission), at that time the world’s largest shipping fleet, while Yewforest had spent her career with Scottish owners since being built in 1910. Intended as a steam whaler, Ullswater was requisitioned on the stocks on the outbreak of war and had spent the war on escort duty.
Their attackers can be seen together at Travemünde in May 1942 on this German-language site, 4th image down: from left to right, S-115, S-112 with the Lichtenstein radar antenna visible, and S-116.
In English waters at any rate the rest of the month was quiet, with no further shipping losses.
