Captain Greenbacker served for almost thirty years before retiring from the Navy in August 1969. Although originally assigned to the aircraft carrier USS
YORKTOWN, most of his sea duty was spent in destroyer escorts, and it is this type of ship with which he is most closely identified.
In his interviews, Captain Greenbacker discusses his experiences while at the U.S. Naval Academy and his duty in the USS
YORKTOWN from July 1940 until June 1942. He comments on the development of the carrier's role in the Navy during World War II, the use of fighter direction, and the ship's involvement in the Battle of the Coral Sea and at Midway.
Captain Greenbacker discusses his transfer to subchasers, reverse lend-lease with the British, and his duty in SC 1472. He describes duty aboard the USS
NEUNZER, and USS
LLOYD E. ACREE during the remainder of and immediately after the war. Included are comments on ship preparation; convoy duty in the Atlantic; supply delivery for operations in the Philippines at Leyte, Mindora, and Luzon landings; and hunter-killer operations in the South China Sea.
