Sunday, September 13, 1942. Japanese attacks on Edson's Ridge, Commonwealth raids on Tobruk, the Laconia Tragedy, Assaults at Stalingrad.

Marine Corps artillery and aircraft, from nearby Henderson Field, cause the Japanese to retreat from Edson's Ridge.  The Japanese, under the command of Gen. Kiyotaki Kawanguchi, tried again that night and broke through the line, but the were stopped by machinegun fire from Hill 123 as well as artillery.

General Kawanguchi was an unusual character who had previously objected to Japanese revenge killings of Philippine government and military officials following the fall of the Philippines.  He stated the killing of prisoners was a violation of Bushido.  Following his service at Guadalcanal, he was put on the reserve list, where he would remain until 1945.  He died in 1961.

The U-156 picked up survivors from the Laconia.  The U Boat commander sought additional help, and even broadcast in English for assistance.

The Germans commenced a large-scale offensive at Stalingrad resulting in house to house fighting, the commencement of that type of combat in the city. It made little progress.

Commonwealth forces commenced Operation Agreement near Tobruk, a series of amphibious and ground raids. They'd take large scale losses to little effect.
