The 2nd Battle of the Matanikau Part II - This is the eighth episode of our Guadalcanal series with historian and author Dave Holland. This episode discusses: What was the plan for 27 September, and why was it inherently risky? How did a breakdown in command-and-control affect the Marines' river-crossing plan at the Matanikau River? How did the Japanese react so fast, and what trap did they set behind Chesty Puller? Why did the Raiders get stopped short of the One Log Bridge—and what happened to Ken Bailey? What role did comms failure play once the fight started to go wrong? How did the amphibious "end run" force end up trapped west of Point Cruz? What made the situation worse once they were cut off—equipment and radios? How did the "HELP" undershirt signal actually work, and what did the pilot do? How was the rescue executed—who coordinated it, and what enabled withdrawal under fire? What were the lessons learnt and why are they important today? Who was Samuel B. Griffith? *]:pointer-events-auto [content-visibility:auto] supports-[content-visibility:auto]:[contain-intrinsic-size:auto_100lvh] scroll-mt-[calc(var(--header-height)+min(200px,max(70px,20svh)))]" dir="auto" tabindex="-1" data-turn-id= "59f613f3-b8a9-420c-bd76-32fbc72206af" data-testid= "conversation-turn-4" data-scroll-anchor="true" data-turn= "assistant"> 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.

What was Japan's Operation Ka, and how was it meant to crush the Marines and recapture Henderson Field in one decisive blow? How did the sinking of USS Wasp and the escorting convoy turn Guadalcanal logistics into a day-to-day survival crisis for the 1st Marine Division? In what ways did Vandegrift and Admiral Kelly Turner pioneer the modern CLF–CATF relationship during the Guadalcanal campaign? Why did the Marines abandon textbook 'defence in depth' and trial a all round defensive cordon with little depth around Henderson Field—and why did it work? How badly did Marine intelligence underestimate Japanese strength around the Matanikau, and how did it effect operational planning? Who was Lt Col "Chesty" Puller in 1942, and why was he Vandegrift's preferred commander for the first major offensive patrol west of Henderson Field? What really happened on Chesty Puller's reconnaissance-in-force over Mount Austin, and how close did his battalion come to disaster? Why does Dave Holland call the failed Matanikau crossing "Alligator Creek in reverse," and what brutal small-unit lessons come out of that sandbar assault? Why did more sailors than soldiers and Marines die in the Guadalcanal campaign, and what does that reveal about sea control and amphibious logistics?
