I was with Alpha Company from late May 1969 (just after Hamburger Hill) to about January 1970 when I transferred to the 159th Aviation Battalion to be a door gunner. 

You other Avengers may be interested to know that I wrote a book titled "The Ghosts of Thua Thien" and had it published by McFarland and Co. in 2008.  It won the Military Writers Society of America's 2008 Gold Medal Award for Memoirs.  If you or anyone is interested, the book is available on Amazon.Com which has several book reviews.  Other bookstores can order the book as well.  A good deal of the book is my recollections of ground ops with Alpha Company. Some may recognize themselves in the book though I used fictitious names at the direction of my publisher.
