TY - JOUR AU - WILLARD, JOHN H. AB - Forces generated by underwater explosions incidental to marine disasters due to operations of war have produced physical injuries which we call the syndrome of "hydraulic abdominal concussion." The outstanding feature of this condition is the forceful compression of the abdomen simultaneous with the entrance of sea water into the bowel through the unprotected anus. This phenomenon was first called to the attention of one of us (L. S. A.) in the winter of 1941 while in Iceland, where it was reported that following the submarine attack on and subsequent loss of one of our smaller naval vessels many of the personnel in the water were killed or injured by the explosion of depth charges carried on the deck of the sinking vessel with detonator mechanisms set for specific pressures. The sinking of the charges to the required depth caused the percussion plungers to become activated.
