I always called my last base “Charlie-1,” but I have not been able to find anything on the Internet about Charlie-1. I have found mentions of Charlie-2 and Charlie-3. They are usually connected to a base called “Cam Lo” after the nearest Vietnamese town. So, I think Charlie-1 and Cam Lo may be the same place. The location given for Cam Lo, about 15 kilometers west of Dong Ha, is about where Charlie 1 was.
I thought there were three strings of bases along the DMZ between North and South Vietnam. There were the Alpha bases, Alpha-1, Alpha-2, etc., which were the closest bases to the DMZ Then came the Bravo base, a little farther south, and finally the Charlie bases, starting with Charlie-1 the eastern-most, a few miles west of Dong Ha. The Wikipedia page for Cam Lo is located here.
This is a map showing Cam Lo, just west of Dong Ha and south of Alpha 4 and Charlie-2. This map also shows Mai Loc, just below Cam Lo. Mai Loc was overrun by the North Vietnamese while we were at FireBase Barbara, which is farther west than this map extends.
I was probably at LZ Sharon from around January to March 1970
At Sharon, w had no infantry support. For defense, we had a quad-50 machine gun and an 85-mm mortar for shooting illumination rounds for the quad-50 and perimeter guards to watch for enemy probes. A quad-50 machine gun is four 50-caliber machine guns on one bracket which is mounted on the back of a 5-ton truck. It was used in previous wars as an anti-aircraft weapon. I ended up shooting most of the illumination rounds because I was up all night working on fire missions for the artillery battery. I was used to computing data to hit targets; so, I could pretty much figure out the mortar illumination settings in my head to adjust fire. In this picture, we are either setting up or removing the mortar when we were arriving at or leaving LZ Sharon.
This is the train that ran along the coast of Vietnam and along highway QL-1. One of our jobs was to protect its track, but the track was blown up almost every night, so that the train seldom ran while I was there.
I think this must be LZ Sally with the 101st Airborne, since they were the only ones who had helicopters at a base where I was posted.
I think this must be the road out to Firebase Barbara.
