I went to Viet Nam in October of 1972. The Paris Peace Talks had just broken down, so President Nixon started a huge bombing campaign on Hanoi. We started getting increasing rocket attacks. By then, we were staying in our "secure" area, but we did have to provide our own area defense of course. I was made a M-60 gunner on M-113 APC and had no idea of what I was doing! Fortunately, we never got the expected attack, only rocket fire. Perhaps the other side was just waiting for the end also.
The Vietnamese came back to the table and a plan was resolved. I think the date for cease fire was Feb 11, 1973? Anyway, we were on perimeter defense that night, into the morning. In the early morning darkness, we began to get some rockets fired into our area. At the predetermined time of cease-fire, the rockets stopped. Eight AM if I remember correctly. I recall this as being a very strange and surreal moment. We were told that we had been in the last combat action of the war. But this is embarrassing to me as I had not experienced anything like others had endured.
Anyway, the war was over. I sure wish it had been the last one.
