How did the arrival of the 7th Marines transform Vandegrift's Guadalcanal strategy from survival to aggressive "active defence"?

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?

Dave is an ex-Marine and was posted to Guadalcananal 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.
