One cloudless afternoon in June 1970 I was bowling along in a minibus crowded with farmers and their families near the small town of Svay Rieng in eastern Cambodia, headed for the capital, Phnom Penh, not long after it had been taken over by the pro-American general Lon Nol. The peaceful road, green-enamelled ricefields, small boys riding mud-caked water buffaloes made, I noted, a refreshing change from the sandbags, barbed wire and watchtowers I had temporarily left behind in Vietnam. War reporting, I thought, has its peaceful moments.
