Michael Bilton, Kevin Sim

Michael Bilton and Kevin Sim are British journalists who collaborated to investigate the My Lai Massacre, one of the most controversial events of the Vietnam War. Bilton worked as a television producer and investigative journalist for Yorkshire Television, while Sim served as a researcher and co-author on their joint project. The pair spent several years conducting extensive research into the 1968 massacre at My Lai village in South Vietnam. Their investigation involved tracking down American soldiers who participated in the killings, interviewing Vietnamese survivors, and examining military records and court documents from the subsequent trials. Their collaborative work resulted in "Four Hours in My Lai," published in 1992. The book presents a detailed account of the massacre based on their investigative reporting and interviews with participants and witnesses. The authors' work contributed to historical understanding of the My Lai incident and its aftermath, including the military cover-up and eventual prosecution of Lieutenant William Calley. Their investigation helped document testimonies from both American soldiers and Vietnamese civilians who experienced the events.

Readers praise "Four Hours in My Lai" for its thorough research and detailed documentation of the massacre. Many reviewers note the authors' extensive interviews with both American soldiers and Vietnamese survivors provide multiple perspectives on the events. Readers appreciate the factual presentation and the authors' efforts to track down participants decades after the incident.

The comprehensive nature of the investigation receives positive mentions, with readers noting the authors uncovered previously unknown details about the events and aftermath. Some readers find the detailed accounts of violence difficult to read, though they acknowledge the importance of documenting these events.

Many consider it an important contribution to Vietnam War literature and appreciate the authors' commitment to presenting factual accounts rather than taking political positions.
