At approximately 1900, Commander River Division 111, LT Edward L. Therrien, fell overboard
from the CCB during operations in the RSSZ. He was wearing complete combat clothing
including tropical boots, flak jacket, helmet and sidearm. LT Therrien was in the water
for about 10 minutes due to lack of maneuverability of the CCB and conditions of darkness.
Two Army personnel jumped in and helped rescue LT Therrien who was unconscious when
brought aboard the CCB. MEDEVAC was requested and the helicopter was overhead as LT
Therrien was brought aboard the CCB. The tide was out and there was a wide stretch of very
shallow water and mud which prevented beaching the CCB to take LT Therrien to a suitable
landing zone for the helicopter; therefore the helicopter was unable to complete its
mission. The patient was evacuated by the CCB to the USS Garrett County miles away.
Patient was given resuscitation aboard the CCB. Satisfactory recovery took several days
because of pneumonia. This experience emphasizes the need for winch lift capability for
MEDEVAC helicopters responding to requirements of the Riverine Assault Force
