In the first six months of war, all the major engagements had been victories. Japanese advances were stopped in the summer of 1942 with the battle of Midway and the landing of the American forces on Guadalcanal and Tulagi in August. The emperor played an increasingly influential role in the war; in eleven major episodes he was deeply involved in supervising the actual conduct of war operations. Hirohito pressured the High Command to order an early attack on the Philippines in 1941–42, including the fortified Bataan peninsula. He secured the deployment of army air power in the Guadalcanal campaign. Following Japan's withdrawal from Guadalcanal he demanded a new offensive in New Guinea, which was duly carried out but failed badly. Unhappy with the navy's conduct of the war, he criticized its withdrawal from the central Solomon Islands and demanded naval battles against the Americans for the losses they had inflicted in the Aleutians. The battles were disasters. Finally, it was at his insistence that plans were drafted for the recapture of Saipan and, later, for an offensive in the Battle of Okinawa. With the Army and Navy bitterly feuding, he settled disputes over the allocation of resources. He helped plan military offenses.
