Good Narrative History
Format: Hardcover
The account of the Guadalcanal campaign was well-written. It has several good maps but it falls short with the two carrier battles associated with the action. There should have detailed maps for the Battle of the Eastern Solomons and the Battle of the Santa Cruz Islands. Aside from this shortcoming, the book provides an excellent, readable history of a crucial confrontation between the US and Japan.

A Very Thorough Accounting of One of the Most Savage Battles of World War 2
Format: Kindle
My father served in the United States Marine Corps during World War 2 and fought in the first offensive battle by the US during the war, the battle for the island of Guadalcanal. He was seriously wounded there and evacuated back to the states where he spent a year in a naval hospital. As a result, I have read many of the books about this battle. This book was particularly interesting because the author described the battle from the perspective of both the allied forces and the Japanese, drawing from historical records and other books. It was a very thorough accounting and demonstrated what a monstrous battle this was. I only wish my father were still alive so that I could have discussed it with him. His experience at Guadalcanal was not something he would often talk about, but considering savagery of what he saw and endured, I understand. If you are interested in Guadalcanal, I recommend this book.

Excellent book on the Campaign!
Format: Hardcover
I highly recommend this book! I have read many books on the Guadalcanal Campaign and I rate this one at the top. It has just the right blend of stragity and personal accounts to keep the story interesting. It is actually a real page-turner, which is rare for a non-fiction work. Wheelan writes in a style that reminds me of the books I read in my teens by Cornelius Ryan and John Toland, which captured my interest in WWII and history. The book jumps right into the invasion, no multiple chapters concerning the planning and build up, but this info is covered later. All phases of this campaign are covered; ground, air and sea. The maps are okay. There are never enough. The author skims over much of the U. S. Army battles after the Marines are relieved, but that seems to be a trend in all of the books on Guadalcanal that I have read.
Overall, this is an excellent book for those who want to learn about the campaign and those who need a re-fresher after reading Starvation Island and Guadalcanal by Frank in years past.

Most complete coverage of Guadalcanal I have read.
Format: Kindle
I have read dozens of WWII books and many touched on the Guadalcanal Battle. I thoroughly enjoyed The Big E and its involvement in the battle. Thas book covered the entire conflict from start to finish. Frankly, I hated to see the book end. The courage and tenacity of all those involved was amazing. To understand the miserable conditions in the area where these men fought was inspiring. To see this battle through the eyes of the American forces and Japanese forces was an added bonus. Thank you for a great read!!!

Shines a light on the reality of the War in the Pacific
Format: Audiobook
Well-written and it really laid out all of the details of how this battle unfolded. I listed to the audio-book, and it was helpful to have the PDF to see a map. How the soldiers on each side endured the battles in the Pacific Theater is beyond me. Man's inhumanity to man that result in this battle outlined here is depressing, but also the sacrifice of those called on to endure and suffer through that inhumanity is equally inspiring and humbling to those whose lives are so comfortable in comparison.
