William T. Diamond, Jr. KIA (My Uncle Billy)
SILVER STAR AWARD
Vietnam War
United States Navy
The President of the United States of America takes pride in presenting the Silver Star (Posthumously) to Seaman William Theodore Diamond, Jr. (NSN: B-501477), United States Navy, for conspicuous gallantry and intrepidity in action on 15 September 1967, during action against communist insurgent (Viet Cong) forces in the Mekong Delta region of the Republic of Vietnam. As fifty-caliber gunner aboard Armored Troop Carrier 111-6 (ATC-111-6), a unit of River Assault Flotilla ONE, operating in support of the 2d Brigade, 9th United States Army Infantry Division, Seaman Diamond participated in a riverine assault against the Viet Cong stronghold in the Cam Son Secret Zone. His unit’s task was to transport and land embarked army troops, as well as to provide beach cover-fire upon landing of these troops. While proceeding up the Rach Ba Rai River to the designated landing zone, the assault force units were suddenly subjected to withering enemy automatic weapons, recoilless rifle, and rocket fire from heavily fortified positions on both banks of the river. With automatic weapons fire hitting all around his gun mount, Seaman Diamond calmly and accurately took the enemy positions under fire. When the first of six enemy B-40 anti-tank grenades struck his boat, wounding him and causing his gun to jam, he took immediate action to clear his weapon and continued to lay down an effective base of suppressing fire until he was fatally wounded by another enemy rocket round which scored a direct hit on his gun mount. Due in no small part to Seaman Diamond’s actions, and the enemy fire which he drew as a result of the effectiveness of his own weapon, the troops embarked in ATC 111-6 were landed successfully and without casualty at the designated landing site. His courage and devotion to duty in the face of intense enemy fire were in keeping with the highest traditions of the United States Naval Service. He gallantly gave his life for his country.
