Reddit reviews NAM: The Vietnam Experience 1965-75

I've read ALOT of Vietnam novels, most of them having to do with personal accounts rather than a historical overview. 100 Miles of Bad Road, is a very detailed and honest approach to life in Vietnam from the perspective of a soldier in the Armored Cav. The Tet offensive is a massive part of that book, and is IMHO one of the best personal descriptions of Tet from the American perspective.

If you want to learn about the logistics & politics of the Tet offensive, look to the man who planned it in Vo Nguyen Giap. Battle field Vietnam, is amazing for that as well.

The only book I've read on Tet is balanced and gives both sides but doesn't really have every piece of information. There are many ways in which Tet was a failure for the NVA and NLF but also many ways it was a victory, so I don't always share the same view as the author in that regard.

Edit: Sorry, Here is the Grand Daddy of all Vietnam books. It's literally a hard cover text book and will provide you with all the information you need for an essay; it also has many Diagrams, photos, and art for any visual presentation. I've owned it for a long time and as far as my collection is concerned is the most comprehensive "all encompassing" text on the logistics & politics. If you don't want to pay all that money there is a wonderful thing called a library.

Good Luck!!
