Planes from four Japanese aircraft carriers struck Darwin on 19 February 1942. Early in the raid, "William B. Preston" got underway and headed for the open sea. As the attack had developed rapidly, Chief Machinist's Mate Blair, a member of the after repair party, went below in company with Metalsmith 2d Class LeRay Wilson, to close hatches and watertight doors. Just after they finished that task, a bomb struck the ship in the compartment in which they were standing, killing both instantly. Their efficient performance of duty, however, limited the flooding suffered by the warship to two compartments. Each man was awarded the Silver Star posthumously.
