The Naval, Military and Air Situation up to 12 noon on 28 December 1939, as reported to the War Cabinet:
Throughout the week under review the Northern Patrol has been maintained by a strong force of cruisers and armed merchant cruisers. A force of heavy ships has been operating to cover the patrol, the convoys to and from Bergen and their homeward bound convoy from Narvik. These convoys arrived without incident.
2. Strong submarine patrols have also been maintained in the approaches to the Skagerrak and Heligoland Bight, but there has been kept comparatively little enemy activity either of surface ships, U-boats or aircraft, due possibly to the bright moonlight and foggy weather in home waters.
3. No merchant ships, Allied or neutral, have been attacked by U-boat, and losses due to mines are small.
4. The second Canadian troop convoys sailed from Halifax on 23 December with a powerful escort of British and French warships, and the military convoy which left India on 10 December, with four animal transport companies, has arrived at Marseille.
13. Following the destruction of the Admiral Graf Spee off Montevideo on 17 December, the forces which had been hurrying towards the Plate and from northward carried out a sweep to locate the German tanker Altmark (20,000 tons), from which the Admiral Graf Spee had fuelled on 7th December. The Altmark is believed to have on board about 300 prisoners, the remainder of the crews of the merchant vessels sunk by the Admiral Graf Spee. This sweep has now been completed without success. The French have disposed a number of submarines and armed merchant cruisers to intercept the Altmark should she work towards the north Atlantic. The area to be covered is a very large one.
British Expeditionary Force
29. Headquarters and ancillary units of the fifth division had now arrived in France, thus completing that formation.
Reports from the British sector of the Saar front state that there has been no activity apart from patrolling.
30. No major operations have taken place. On the Rhine-Moselle found several minor German attacks were launched on French positions and successfully repulsed.
On the Rhine front a tentative attempts by the garrison of a German casemate to fraternise with French troops was interrupted by French machine gun fire.
Royal Air Force Operations.
Operations against German Naval forces
35. During the week under review a number of reconnaissances have taken place with a view to locating and attacking enemy naval forces.
On the 24th December seventeen Wellingtons made a reconnaissance of an area off the west coast of Denmark and sighted several patrol ships in a position 40 miles north west of Horn Reefs. The ships were steaming in pairs and, after challenge and counter challenge, they opened fire on the aircraft with pom-poms. Three Wellington was attacked, dropping eight 500 lb. bombs from a height of 4000 feet. Observations were rendered difficult by clouds and it is not known if any hits were made.
Russo- Finnish Operations
Situation on land.
50. Information received during the period under review shows that the situation of the Finnish armies has improved considerably in all sectors.
51. On the Karelian Isthmus a major Soviet offensive which took place between the 19th and 21st of December failed to make any impression on the Finnish defences, though it was accompanied by very heavy bombardment by artillery and aircraft. Lack of success appears to have reacted unfavourably on the morale of the Red Army; and, though the offensive has been continued, it has achieved nothing.
52. On the eastern frontier Finnish troops have scored a number of successes, helped by severe weather and by increasing Soviet maintenance difficulties.
53. These successes have greatly improved Finish morale and the High Command are now very confident. They find the enemy’s leadership feeble, his tactics poor and wasteful, his troops inferior. They express themselves as able to hold the Karelian Isthmus against any attack the Soviet can make and consider that maintenance difficulties will prevent attacks in other sectors developing on a dangerous scale. In spite of Finnish confidence it is doubtful whether it would be physically possible to hold any position against the weight of artillery which the Soviet could deploy against the Karelian Isthmus position, unless the defenders possess large quantities of artillery and aircraft to carry out counter battery bombardments on a large scale. It is, therefore to be hoped that Finnish optimism will not lead them to undertake any dangerous counter offensive, which might well result in losses of men and material the country could ill afford. It should be remembered that the Russian soldier always gives a much better account of himself in defence than in attack.
On the Soviet side it appears that the High Command have been attempting to reverse the course of events by bringing out further reinforcements, a doubtful remedy in a war where the lack of communications and limited frontages are the decisive factors. There is, however, some chance that Russian numbers may tell in the south, once the ice on Lake Ladoga and the Gulf of Finland become thick enough for Soviet troops to operate across them.
The latest reports suggest that there are 11 Soviet infantry divisions in the Karelian Isthmus and 16 divisions between Lake Ladoga and the Arctic Ocean. A partial evacuation of Leningrad is reported to have taken place so as to facilitate the working of the principal base of these large forces.
