This Charlie was a rifleman in the US 25th Infantry Division who documented through photographs his involvement in the Vietnam war.
Vietnam was the first war in history to be so widely reported through still and TV images, and it was this visual imagery which led to so many street and campus protests, and eventually America's decision to pull out. It was a costly and humiliating defeat for the US and even more costly for the Vietnamese, many of whom still die every year in land mine and other ordnance explosions and the effects of the defoliant, Agent Orange.
For me, as a kid in the sixties, the war held a strange fascination as I viewed it as a struggle between the proponents of freedom and repression. I collected images from anywhere I could find them: Time magazine, Life, newspapers and books. When the war ended I was fourteen and had thousands of photos in scrapbooks, in boxes and stuck on the bedroom wall.
Time moves on and perspectives change (and I grew up) and now Vietnam is a country I love to visit whenever I can, to mix with a people of unique warmth and humanity.
The debris of war is still there and I've been through the Viet Cong tunnels, visited the museums and spoken to ex-fighters.
There's no bitterness and no recrimination, just a wish to get on and see their country prosper. American tourists are always made to feel welcome and the past has been forgiven, but not forgotten.
