The President of the United States of America takes pleasure in presenting the Coast Guard Medal to Engineman Third Class Earl H. Leyda, United States Coast Guard, for heroism during rescue operations following a violent explosion in the Oswsego Water Works Tunnel, at Oswego, New York, on the evening of 18 August 1957. Engineman Third Class Leyda volunteered with two other men to attempt the rescue of three construction workers trapped somewhere in the 6,200 foot tunnel under Lake Ontario. Other workers had made several rescue attempts but were forced to withdraw because of fumes, lack of oxygen, and the distance involved. With the aid of Coast Guard OBA equipment, Engineman Third Class Leyda and two other members of the rescue party entered the gas and smoke filled tunnel. Loose rock, water seepage and toxic gas added to the hazards. Engineman Third Class Leyda and the others had proceeded approximately 5,900 feet underground when they located the bodies of the victims, apparently killed by the explosion. Boatswain’s Mate Third Class Leyda demonstrated initiative and fortitude in spite of imminent personal danger during this rescue operation. His unselfish actions and unwavering devotion to duty reflect the highest credit upon himself and the United States Coast Guard.
