Eastern Front

The German radio announces the discovery of eight communal graves in the Katyn forest near Smolensk, containing the remains of 4,150 Polish officers deported by the Russians in 1940 and murdered. The story says they were all shot in the back of the neck with their hands tied. The USSR denies the accusation. The truth has never been established.

SOVIET COMMAND

The Soviets begin the large-scale mobilization of civilian labor to dig hundreds of miles of trenches and defense works in teh Kursk salient. The Stavka has already identified this area as the most likely location of a renewed German offensive in the summer. By the end of the month more than 150,000 men and women are at work digging trenches and tank traps, while the Voronezh and Central Fronts lay minefields and construct elaborate anti-tank positions. The Stavka has, after considerable deliberation, decided to fight a defensive battle before unleashing its own counteroffensive.

Germany, Strategy

Hitler issues Operational Order No 6 for the destruction of the enemy forces in the Kursk salient. Codenamed Operation CITADEL, it will begin on May 3. Hitler realizes that 1943 is his last chance to avoid defeat in the East, a position made more urgent by the impending defeat of Axis forces in North Africa, U-boat losses in the Atlantic and the threat of an Allied invasion of Western Europe. Thus, Germany's ultimate fate depends on a favorable outcome on the Eastern Front in 1943. The Führer believes that if the Soviets can be exhausted, they will be more receptive to a negotiated separate peace.

New Guinea

The Japanese air offensive continues with attacks on Port Moresby, where the port installations are damaged, but not seriously.

Attack on Allied Airfields
On 12 April 1943, the 13th Squadron was on the receiving end when over one-hundred Japanese planes attacked Allied airfields in the area of Port Moresby, New Guinea. The squadron had eight B-25s at this time, and all of them were damaged or destroyed, which temporarily put the squadron out of action until they were re-equipped with the modified low level strafer B-25's. Of note is that all R.A.A.F. personnel were withdrawn from American squadrons after this attack.

North Africa

TUNISIA

By the afternoon the Axis troops have dug in on the Enfidaville line. The attacks by the 8th Army continue, and the Allies occupy Sousse, the last supply port on the Tunisian coast. Now only Enfidaville separates the 8th Army from Tunis.

It is agreed that the US II Corps will remain under the command of the 18th Army Group rather than the British 1st Army, but the 1st Army is to issue the necessary orders for the US II Corps in order to co-ordinate its operations with 1st Army's drive on Tunis.

In the British 8th Army area, Gen Montgomery, in response to a request from Gen Alexander for reinforcements for the British 1st Army, selects the 1st Armored Div and the King's Dragoon Guards for the mission. The X Corps captures Sousse and continues northward.

In the British 1st Army's V Corps area, the US 9th Div begins the relief of the 46th Div. The 78th Div continues clearing the region northwest of Medjez el Bab.

AFS ambulances delivered patients from the front to a Polish dressing station behind 8th Army lines near Sousse. Camouflage nets protected the dressing-station tents during enemy plane attacks.
