The ill-fated Goettge Patrol
August 2026, at the mouth of the Matanikau River. I am exploring the sites associated with the ill-fated ‘Goettge Patrol’ of 12-13 August 1942. The action happened over a very small area encompassing the beachline just west of the mouth of the Matanikau, near the old village of Matanikau, which is now overrun by urban sprawl. In 1942 the jungle extended all the way to the beach and there was very little settlement in the area. The area today is occupied by small businesses, parking lots, and dilapidated buildings. The actual beach site is, unfortunately, covered in trash, especially plastic water bottles, that wash down the Matanikau and get deposited on the beaches.
Situation
Where were the Japanese garrison?
After the landing at Beach Red on 7 August 1942, the 1st Marine Division moved quickly to secure the unfinished airfield at Lunga Point. The airfield was secured by the afternoon of 8 August, but the site was deserted. The Japanese had clearly departed in a hurry and left much of their equipment behind. Over the following days, the Marines were subjected to a rapid air and naval response by the Japanese forces. Japanese aircraft from Rabaul bombed the airfield and the ships standing offshore. On the night of 8/9 August, the US Navy suffered its worst defeat in history during the Battle of Savo Island. To preserve his scarce naval airpower, Admiral Fletcher withdrew his aircraft carriers out of range of the Japanese bombers. Without air cover, Admiral Turner also made the decision to withdraw the amphibious fleet from Guadalcanal.
Ashore, the Marines wondered what had happened to the hundreds of Japanese troops and several thousand labourers who had been working on the airfield. One of their first breakthroughs was the capture of a Japanese sailor who revealed that there was a large group of Japanese troops west of the Matanikau River who had no supplies and would be willing to surrender
A patrol beyond the Matanikau
On 12 August, Marine patrols reported seeing a white flag in the region of the Matanikau River. Together with the information provided by the prisoner, the Divisional staff saw an opportunity to potentially eliminate the remaining Japanese threat on Guadalcanal.
At this time, the perimeter around Kukum and the airfield was still a series of outposts rather than a fixed line. The ground west of the perimeter, toward the Matanikau River and Point Cruz, was not secured by American troops. It was into this unknown ground, at night, by boat, that a Marine patrol would be sent on the strength of a single interrogation. The objective area was roughly four and a half miles west of Kukum by water: a stretch of coast either side of the Matanikau’s mouth, with Point Cruz as the reference point and thick jungle running down almost to the beach.
