In June 1942, the Japanese army suffered heavy losses by the US military during the Battle of Midway and was forced to stop its all-out offensive. However, it desperately wanted to regain its strategic initiative. At the end of June, it sent troops to build an airport on Guadalcanal, hoping to use its air force to threaten the US-Australia (Australia) transportation line and expand its aggression in the South Pacific. The U.S. military decided to fight back against Japan's expansion and sent 20,000 troops to land on Guadalcanal on August 7, 1942. The Japanese army lost its resistance and fled into the jungles of the northwest of the island. Important military facilities such as airports fell into the hands of the US military. The Japanese army continued to send reinforcements, organized many counterattacks, and fought more than 30 times with the US fleet in nearby waters. Japan suffered heavy losses. 24 large warships, more than 600 aircraft were destroyed, and 24,000 soldiers were annihilated. Allied Pangli's losses were only 5,800 people.

From then on, the Japanese army fell on the defensive and was passive step by step until defeat and surrender.
