The main Soviet attacks against the Mannerheim Line, around Summa, continue with less force. The first Soviet offensive on the Isthmus runs out of steam. By evening the main defensive positions are entirely under Finnish control.
At Summa, the Soviets are becoming worn out by their repeated tank raids into the nearby frozen swamp which turn into killing zones by defenders throwing Molotov Cocktails and satchel charges. The weather is brutal, -20C, and the Soviet tanks and other armour is having difficulty due to the elements. The tanks can break through the Finnish lines, but they are unable to penetrate the fixed defenses that hold the key to the Mannerheim line. Without infantry support, the tanks are then picked off individually. When the fuel runs out, the vehicles freeze solid and then the Soviets must advance on foot through terrain the Finns handle with ease on skis.
The Finnish II Army Corps commanded by Lieutenant-General Öhquist are ordered to launch a counteroffensive.
The Soviet Army calls off the attack on Summa. A correspondent watches Finns impose heavy losses.
At Suomussalmi, the Finnish 27th Regiment is reinforced and now called the 9th Division. It has had the Soviets in the village surrounded for a week without any significant attempts to break the blockade by the relief force. The Soviet 44th Division has enough problems as it gets cut up by the Finns on the Ratte road. The commander of the 163rd Division trapped in the town, Andrei Zelentsov, asked permission to retreat from Suomussalmi. Permission is denied and he is told that more troops are being sent to rescue him.
The Finns take the initiative at Salla.
At Salla, Mannerheim has sent a division from his strategic reserve at Helsinki. It is used to drive the Soviet 122d Division, which has advanced along the southern fork almost to Kemijarvi, back to Salla. The entire advance out of Salla on both the north and south forks of the road has been repelled.
At Joutsijärvi in the Salla sector a Russian battalion manages to infiltrate behind the Finnish positions at Mäntyvaara. The Russian battalion is finally destroyed in hand-to-hand fighting. A battalion of the Soviet 122nd Division surprises two companies of Detached Battalion 17 which had been moved into reserve. After four hours of fighting, the enemy withdraws with the loss of 300 dead. Finnish losses are 17 dead, including the two company commanders.
The Soviet 122nd Division is cut off by Finnish attacks while advancing toward Salla from positions near the White Sea.
At Taipale, the fighting has diminished considerably after the Soviets stopped attacking strong points that they can’t overwhelm.
The Battle of Kollaa is becoming a long, drawn-out affair, which is exactly what the Finns wanted.
Colonel Paavo Talvela is promoted to Major-General, and Lieutenant-Colonel A.O. Pajari to Colonel.
The Finnish “Group Talvela” named after now-Major General Paavo Talvela), which is primarily 16th Infantry Division, attacks Soviet 139th Rifle Division. It remains surrounded at Ägläjärvi. Soviet 75th Rifle Division has been sent as a relief but it is accomplishing little.
In Ladoga Karelia, the enemy bombs and machine-guns a train carrying evacuees at Jänisjärvi Station in the parish of Harlu. 16 civilians are killed. Soviet aircraft also bomb Matkaselkä. Five people are killed and three seriously injured. The Soviets bomb Kontiomäki. One person is killed.

German armored ship Admiral Graf Spee’s former commanding officer, Kapitan zur See Hans Langsdorff, commits suicide at Montevideo, Uruguay.
“I can now only prove by my death that the fighting services of the Third Reich are ready to die for the honour of the flag. I alone bear the responsibility for scuttling the panzerschiff Admiral Graf Spee. I am happy to pay with my life for any possible reflection on the honour of the flag. I shall face my fate with firm faith in the cause and the future of the nation and of my Führer.”
Meanwhile, British experts examine the radar equipment on board the wreck of the Graf Spee. The superstructure of the panzerschiffe is above water. At some point, local British authorities purchase the salvage rights to the Admiral Graf Spee for £14,000 from the German government. They examine the radar range finder and report back their findings to Fred Hoyle at the British Admiralty in order to develop countermeasures.

The Swedish steam merchant Mars struck a mine and sank one mile east of St. Marys Lightvessel near Blyth off the eastern coast of England in the North Sea (55° 04’N, 1° 24’W). At 14.30 hours the Mars struck a mine, laid earlier the same day by U-22, and sank. Of the ship’s complement, 7 died and 15 survived. Nine of the survivors, four of them injured, were landed at North Shields a few hours later. The 1,877-ton Mars was carrying wood pulp and was bound for London, England.

Another 100 tons of tin, however, consigned to a Swiss buyer, are put on the “detained list” and held in Genoa at the disposal of the British consul. That turn of affairs prompts U.S. Ambassador in Italy William Phillips, to take up the matter with the British Ambassador, who expresses his awareness of the “irritation and resentment…in American commercial and shipping circles” over the seemingly “arbitrary, careless, and casual” methods shown by the British contraband control people.

Although a new trade treaty with the United States cannot be negotiated before January 26, the Japanese expect or hope a working arrangement on lines that will not require the United States Senate’s assent can be negotiated.
The Cabinet faced increasing criticism today because of its action in announcing early reopening of the Yangtze and Pearl Rivers in China to general international commercial traffic. Ultra-nationalists accused the government of weakness and warned Premier Nobuyuki Abe they would not tolerate any policy of “appeasement” toward the United States that would tend to encourage a continuation of resistance by Generalissimo Chiang Kai-Shek.
The ultra-nationalists, equally opposed to suggestions for a “deal” with Russia that would result in a cessation of Russian support to China in return for concessions to Moscow by Japan, demanded that the government force the China war to a victorious conclusion under the Empire’s own resources. Indicative of popular opinion, 586 prominent persons, including former government officials and army officers, met late yesterday and adopted a resolution urging the government to take “appropriate measures” for disposal of the “China incident.”

Shiranui operated with the Kido Butai aircraft carrier force for the first few months of WW2, including taking part in the Pearl Harbor strike force. The only break from this came at the biggening of March, where Shiranui involved herself in a small surface action when she helped to sink the Dutch freighter Modjokerto. Shortly after escorting troop convoys during the battle of Midway, Shiranui’s entire forward 3rd was blown off by a torpedo from the submarine USS Growler. Repairs lasted until the end of 1943, with the damaging being extensively photographed. After a series of patrol duties, she took part in the battle of Leyte Gulf, nearly surviving the battle, but being sunk with all hands by dive bombers from USS Enterprise during its final stages.
