Maruyama vs Vandegrift in the fight to control the Matanikau River. The 3rd Battle of the Matanikau Part I - This is the ninth episode of our Guadalcanal series with historian and author Dave Holland. This episode discusses: How did the Japanese plan to exploit the Second Battle of the Matanikau to set up their October 1942 offensive to retake Guadalcanal?

What was Japan's concept for suppressing Henderson Field before the main assault?

What was the "One Log Bridge" on the Matanikau River, and why did it matter tactically? How did the weather have on the Matanikau operation? Dave Holland is an ex-Marine and was posted to Guadalcanal with the Australian Federal Police. He regularly leads battlefield study tours through the area. He is a world-leading expert on the battles of Guadalcanal and author of Guadalcanal's Longest Fight - The Pivotal Battles of the Matanikau Front. Check out the show notes for the…
