Robin Monahan, Falls High School class of 1962, said he doesn’t have the self-discipline to write a book of his experiences serving in a field hospital in Vietnam, but talking about it seems good therapy.And, he said, it may help others who experienced the things he did.“This has been a long time in coming,” he said.When Monahan came home from Vietnam and left the service in 1968, “it was difficult, impossible actually, to talk to anyone about my experiences in Vietnam out of fear of uncomfortable discussion or even hostility, given the attitude toward veterans at the time.”He served from April 21, 1967, to April 1, 1968, during the Tet Offensive, in a surgical field hospital, working in one of six operating rooms that worked 24 hours a day for 45 days.“It gave me a new perspective of what hard work is, working 16-hour shifts,” he said.“Twelve months I worked in an operating room and it’s a special sort of trauma,” he said.
