...entitled khon thai nai gong thap nazi - The Thai in the Nazi Army. It is the story of one Vicha Dhitavad (that's how it's transscribed in some places in the book, though "Wicha Thitawat" would be more accurate), told by himself (partly in the form of letters or diary entries, it seems). Fourth edition, I think, the previous ones being from the 50s and 70s.
I don't have the slightest idea why (with more time at hand I could possibly have found out), but this guy was trained in Germany and, unlikely as it may seem, served as a soldier in the Wehrmacht during WWII. The book included some pictures of him in German uniform and a chronology of his life at the back. Apparently he attained the rank of a captain (as a Funker = radio operator), and after the war went on to become a colonel of the Thai army, and still later served as the Thai ambassador to Denmark, Norway and Iceland.
The late Colonel Wicha (1917-1977) was initially went to study on Army Communication System in Belgium in 1938.
However, the WWII had forced him and his friends to study in Germany Military Academy and he got into a rank of Captain...after graduation.
...he and his friends had become POWs after being arrested by US Army .... It take about a year to get released ... and went back to Thiland in 1947.
