Summary of Action


On 23 May 1939, Chief Metalsmith James Harper McDonald displayed extraordinary heroism during the rescue and salvage operations following the sinking of the USS Squalus.


The submarine had gone down during a test dive off the New England coast after catastrophic flooding, trapping crewmen deep underwater in a race against time for survival.


As one of the Navy’s master divers, McDonald became a key figure in the dangerous operation to rescue survivors and recover the submarine.


Working under some of the most hazardous underwater conditions imaginable, he directed diving operations and personally conducted critical dives beneath the ocean surface.


The rescue effort required repeated descents into deep, cold waters with limited visibility, dangerous currents, and constant risk to the divers themselves.


Any failure in equipment or procedure could easily have resulted in additional deaths.


Despite these dangers, McDonald demonstrated exceptional leadership, technical expertise, and unwavering devotion to duty throughout the operation.


His masterful diving skill and tireless work helped make possible one of the most significant submarine rescue efforts in U.S. Navy history.


The successful rescue of surviving Squalus crewmen became a landmark achievement in naval rescue operations, and McDonald’s courage and professionalism were central to that success.
