Malaya Campaign
The battle on the border - Wellingtons and Wellesleys Singora and the Japanese armament depots on the Kra Isthmus during the night. This kind of bombardment is not very effective.
At dawn, the Hudsons of Sqn 7 and 8 of the RAAF attack the Japanese columns on the march from Jitra to Alor Setar, with more success.
At that time, Japanese troops were already heavily engaged against the Commonwealth forces around Alor Setar. A limited Australian counter-attack, supported by tanks, pushes the Japanese back to the (destroyed) railroad bridge for a while. At 11:00, as the D3A1 dive bombers appear over Alor Setar, the operation is interrupted to avoid exposing the precious tanks. Until the night, the heavy "infantry tanks" are used as mobile redoubts, effectively blocking Japanese counter-attacks. However, the commander of the 8th Australian Infantry Division, Major-General H. Gordon Bennett, has to prepare his withdrawal to Gurun, where the 11th Indian Division holds a new defense line.

The Battle in South Malaya - Japanese forces enter Kaltang at first light, after having forced the Commonwealth troops back in a series of turning movements. However, under constant harassment from Allied artillery, the Japanese are unable to prevent their opponents from retreating in good order towards Kluang airfield. However, in the course of the afternoon, it becomes clear that, as the Commonwealth troops continue to retreat westward, a serious crisis is brewing on that front.
On the other hand, the Japanese advance towards the south, towards Kota Tinggi, is continually slowed down by roadblocks, minefields and small British counter-attacks.

The Air Battle of Singapore - Japanese Army Ki-21 bombers based at Kuching attack the Singapore grounds without escort. This presumption is punished by the loss of three of them to two Hurricanes and a lone Martlet.
"With my departure," writes Yvon Lagadec, "Danny Potter had become the only FAA fighter pilot in the Far East, and even the only fighter of one of the allied naval aviation the area! He took advantage of this to equalize the score of our friendly duel, started in the Mediterranean. On the evening of January 20th, we were at eleven all!"
At the end of the day, considering that the Japanese dominated too clearly the airspace of Malaysia to risk other pilots, the local command decides to transfer some units to the Palembang-II airfield of the ML-KNIL, in Sumatra, to reconstitute them there. The first pilots to be transferred are those of the RAAF Hurricane squadrons (and Danny Potter). It is planned to use Palembang-II for the refueling operation of Sabang from Rangoon.

Singapore - In the evening, returning from Bandœng where he conferred with General Wavell and other senior officers (including the French representative, Admiral Decoux), Lord Gort announces that Air Marshal Brooke-Popham has been relieved of his responsibilities in Malaya. It is not a sanction, but the creation five days earlier of the ABDAF Command removes any justification for the existence of Far East Command. Moreover, the Air Marshal had been giving signs of physical and nervous exhaustion for some time.
GOC Malaya, General Percival, being only acting Lieutenant General, General Gort proposes to Churchill to take personal charge of the defense of Singapore and Malaya, Percival playing the role of a chief of staff. "It is clear, Prime Minister," Gort explains in his message to him, "that the situation here is very unfavourable. By taking command of His Imperial and Royal Majesty's Army in the region in person, I intend to force the Japanese Emperor's Army, whose officers place their honor so high and behave so often, I am told, like barbarians, to pay the highest price for Singapore and Malaya. For this purpose, I know that I can count on the loyalty to the Crown of men all over the Commonwealth who will fight to the end and who can, to the end, count on my presence by their side.
God save the King."
Churchill is sensitive to these arguments. However, in order not to overshadow Wavell (at ABDAF Command) and not to appear to be demoting Percival, this new command remains unofficial for seven weeks, Gort having in theory only an extended inspection mission.
