Secret Commandos by John L. Plaster. Autobiography of a soldier who was on a recon team inserted into Laos and Cambodia during the Viet Nam War. They were on their own for the most part : no dog tags, or insignia. Three Americans, and a few Montagnards per team. Inserted and picked up by chopper. Nearly always surrounded by hundreds of NVA.
"Reveille In Washington, 1860-1865" by Margaret Leech. Copyrighted in 1940 so might not be easy to find a copy (reprinted by Time-Life 1980). An interesting and very in depth look into the politics of Civil War. A different perspective from Doris Kearns Goodwin's recent best seller, "Team of Rivals, The Political Genius of Abraham Lincoln." Leech doesn't think Lincoln was such a genius.
Here's a great read: "Today I Baled the Hay to Feed the Sheep the Coyote Eat" written and illustrated by Bill Stockton. Stockton was a sheep rancher (born into it at Grass Range, MT) who was also highly educated - and WWII vet if I remember correctly. His philosophy of life and death on the ranch is laced with emotion and humor. The writing is absolutely amazing for a lowly sheepherder. Anyone who has experienced that country and the people who live there ... or used to live there ... should read this book.
