military casualties. Throughout the May Offensive, however, the enemy was unable to penetrate the cities to any great extent. As a result, the ratio of military casualties to civilian casualties was higher and resulted in a greater number of out-of-country evacuations. At the request of the brigade headquarters, the 7th Air Force Surgeon's Office inactivated the 25th Casualty Staging Flight (CSF) at Qui Nhon on 11 July 1968. This CSF had been utilized as a staging area for out-of-country evacuation of patients from the 67th Evacuation Hospital. Evacuation out-of-country from Qui Nhon was disadvantageous because all flights terminated at Clark Air Force Base. where it was necessary for patients regulated to Japan to remain overnight. As a result, patients lost at least one addi­tional day prior to being further evacuated. After the 25th CSF was inactivated, all US military patients from the Qui Nhon area were evacuated to the 26th CSF at Cam Ranh Bay for further evacuation directly to Japan utilizing regularly scheduled Military Airlift Command flights. Korean patients were also evacuated to the 26th CSF for movement to Clark Air Force Base, and further evacuation to Korea. The primary advantages were the elimination of delays enroute to destination hospitals and consolidation of out-of-country evacuations at casualty staging facilities serviced on a regular basis by Military Airlift Command flights. During 1968, the average daily beds occupied by MEDCAP patients throughout the brigade's medical treatment facilities rose from 61 per day in January to 285 per day in December. The brigade observed that as military activities decreased, the number of MEDCAP admissions increased. Civilian War Casualties accounted for approximately 27% of the total patients in brigade facilities. This figure remained fairly stable since April 1968. Following the May Offensive, the number of POWs hospitalized throughout the brigade remained constant at about 400 beds per day. Aeromedical Evacuation Aviation activities at the beginning of 1968 were similar to those of 1967. Workload continued to increase slightly with a new high of 12,520 evacuated in January. The Tet Offensive in February substantially increased the workload to 16,885 and the all-time high of 21,915 patients were evacuated by brigade aircraft during the month of May. Workload throughout the remainder of the year was fairly level in the range of 14,000 to 15,000 patients evacuated monthly with the exception of August and September when evacuation rose to nearly 17,000 in each month.
