The President of the United States of America takes pleasure in presenting the Silver Star to Rear Admiral [then Captain] Joseph James Clark (NSN: 0-17006), United States Navy, for conspicuous gallantry and intrepidity as Commanding Officer of the Aircraft Carrier U.S.S. YORKTOWN (CV-10), during operations against enemy-held islands in the Central Pacific Area, from 31 August 1943 to 5 December 1943. Skillfully handling his ship during these widespread and extended operations, Rear Admiral Clark enabled aircraft based on his carrier to launch damaging attacks on enemy aircraft, shipping and shore installations on Marcus, Make, Jaluit, Makin, Kwajalein and Wotje Islands. During the day and night of 4 December 1943, when the YORKTOWN was under severe enemy attack almost continuously for one five-hour period at night, he maneuvered his vessel so expertly that all attacks were repelled without damage. By his devotion to duty throughout, he contributed materially to the success of our forces and upheld the highest traditions of the United States Naval Service.
