North Africa

In the Battle of Wadi Akarit the 8th Army breaks through the Axis lines south of Sfax, but fails to exploit its initial success.

In the US II Corps area, while the 1st and 9th Divs press forward toward the general line intended originally for the first phase, Task Force Benson, 1st Armored Div, follows up closely and reaches the road juntion northeast of Djebel Berda. As a diversion in the Maknassy area, Combat Command B attacks Djebel Maïzila, and Combat Command C demonstrates at Djebe Naemia. After nightfall the enemy disengages and for the most part withdraws eastward under cover of artillery fire. The II Corps is ordered to apply maximum pressure on the 7th.

The British 8th Army begins an assault on the Wadi Akarit line, from which the enemy begins withdrawing during the night. The XXX Corps jumps off before dawn with the 51st Div on the right, the 50th Div in the center, and the Indian 4th Div on the left. Progress is made, particularly on the flanks, but tenacious resistance and counterattacks prevent a complete breakthrough. The X Corps, which is to drive through the XXX Corps' bridgehead, moves forward at noon. The New Zealand 2nd Div, which reverts to the corps, leads the drive.

South Pacific

After the disastrous Battle of the Bismarck Sea (see March 3-5), Yamamoto feels that some action on a huge scale is necessary to halt the American pressure in every sector. In view of Japanese losses in warships and transports there can be no question of a naval operation, nor of an operation on land. The only possible answer is a great air attack 'which will weaken the claws of the American eagle'. The Japanese bases in New Guinea and the Solomons are under threat. It is clear that the Americans are aiming at the capture of the northern Solomons and the important base of Rabaul, in New Britain. The fall of Rabaul would give the enemy a jumping-off place for an attack on the Philippines and might allow them to cut off Truk, the key point of the Japanese imperial forces in the Pacific, their 'Pearl Harbor'. Since there are many signs that the American offensive is to be launched soon, Yamamoto decides to act at aonce. He concentrates all available air formations at Rabaul, at Kavieng in New Ireland and at Bium in the south of Bougainville. Even the aircraft from the aircraft carriers are transferred to land bases to take part in Operation A. 350 aircraft are assembled and regrouped, ready for action.
