gave the United Nations their first toehold in the area of enemy defenses protecting Rabaul, center of Japanese power in the Southwest Pacific.
The American part in the Buna-Sanananda campaign, in which Australian and American troops defeated "the invincible Imperial Army" of Japan, is the subject of this pamphlet. The proportion of American troops in the Allied forces at Buna was much greater than at Sanananda, and for this reason the Buna operation receives the more detailed treatment. The story is set in a background of fever-ridden swamp and jungle, where American soldiers lay day after day in waterlogged fox holes or crawled through murderous fire toward enemy positions they could not see. Despite all the difficulties imposed by terrain, climate, and the formidable strength of Japanese fortifications, despite failure in many heroic attacks, the effort was carried through to a final and smashing success. This campaign and the almost simultaneous action on Guadalcanal were the first victorious operations of U. S. ground forces against the Japanese.

On 21 and 22 July a Japanese convoy of 3 transports, 2 light cruisers, and 3 destroyers reached Gona and disembarked Maj. Gen. Tomitaro Horii with about 4,400 troops. Allied Air Force attacks succeeded in setting fire to 1 transport. Additional troops and supplies poured in during the next few days. By 13 August 11,100 men had landed and the drive on Port Moresby began. The Japanese fought their way across the deep gorges and razor-backed ridges of the Owen Stanley Mountains and descended the southern slopes to within 32 miles of the port. Here Australian resistance stiffened and on 14 September the advance was held at Imita Range, south of Ioribaiwa.
During the next 2 weeks the Allied Air Force continued relentless strafing and bombing of the Japanese supply lines running over the mountains to Buna, Sanananda, and Gona. The enemy, half-starved, attacked on front and flank by the Australians, yielded Ioribaiwa on 28 September and began to withdraw hastily up the trail. During the critical last days of August, Japanese units had landed at Milne Bay 2
