The President of the United States of America takes pleasure in presenting the Silver Star to Major Donald Keith Yost (MCSN: 0-5453), United States Marine Corps, for conspicuous gallantry and intrepidity in action as leader of a flight of fighter planes attached to Marine Aircraft Group FOURTEEN, FIRST Marine Aircraft Wing, in combat with enemy Japanese forces in the Solomon Islands Area on 23 and 24 December 1942. Leading his group of four fighters as escort for our dive bombers attacking Japanese land installations at Munda Point, Major Yost daringly intercepted enemy planes attacking the bombers and, despite heavy anti-aircraft fire, destroyed two of the hostile planes and completely disrupted the assault. The following day, he again led his command against the enemy with such outstanding skill and grim determination that ten Zeros were shot down, he, himself, accounting for four of them. His superb leadership and indomitable fighting spirit reflect great credit upon himself, his command, and the United States Naval Service.
