Burma

The demolition of oil installations around Yenangyaung, the largest oil field in the Far East, is begun in order to deny them to the Japanese. The Japanese begin to surround the Chinese T-55th Division in the area of Mauchi-Loikaw.

Eastern Front

There is renewed fighting near Vyazma as the 50th Army launches a strong attack to free the encircled 33rd Army and Group Belov. Initial progress is good; by afternoon leading elements of the 50th Army are only 3 miles from Group Belof, having taken the Zaitsevo heights by storm. The Luftwaffe then enters the battle, launching a crushing attack upon the advancing units. Repeated assaults inflict crippling casualties, forcing the 50th Army to fall back.

Mediterranean

The British submarine Upholder is sunk by the Italian motor torpedo boat Pegaso north of Tripoli with a loss of 33 on board.

Occupied France

(15th?)French Resistance carries out a grenade attack on the German HQ building in Arras.

Vichy, Politics

Pierre Laval forms a new government in Vichy. Germany has been increasingly dissatisfied with its Vichy partners. Pressure is exerted, therefore, to bring about a completely subservient regime. Petáin is to remain as head of state. Laval becomes chief of government and assumes actual direction of the Vichy administration.
