Thomas Cassin Kinkaid (3 April 1888 – 17 November 1972) was an admiral in the United States Navy, known for his service during World War II. He built a reputation as a "fighting admiral" in the aircraft carrier battles of 1942 and commanded the Allied forces in the Aleutian Islands Campaign. He was Commander Allied Naval Forces and the Seventh Fleet under General of the Army Douglas MacArthur in the Southwest Pacific Area, where he conducted numerous amphibious operations, and commanded an Allied fleet during the Battle of Leyte Gulf, the largest naval battle of World War II and the last naval battle between battleships in history.
Born into a naval family, Kinkaid was ranked in the lower half of his class on his graduation from the United States Naval Academy in June 1908. His early commissioned service was spent aboard battleships. In 1913, he began instruction in ordnance engineering and served in that field for many years. He saw action during the 1916 United States occupation of the Dominican Republic. During World War I, he was attached to the Royal Navy before serving as gunnery officer aboard the battleship USS Arizona. After the war, he was assistant chief of staff to the Commander U.S. Naval Detachment in Turkey. Kinkaid received his first command, the destroyer USS Isherwood, in 1924. He was executive officer of the battleship USS Colorado when the 1933 Long Beach earthquake struck, and participated in relief efforts. He received his second command in 1937, the heavy cruiser USS Indianapolis.
From 1938 to 1941, Kinkaid was a naval attaché in Italy and Yugoslavia. In the months prior to U.S. entry into World War II, he commanded a destroyer squadron. Promoted to rear admiral in 1941, he assumed command of a U.S. Pacific Fleet cruiser division. His cruisers defended the aircraft carrier USS Lexington during the Battle of the Coral Sea and USS Hornet during the Battle of Midway. After that battle, he took command of Task Force 16, a task force built around the carrier USS Enterprise, which he led during the long and difficult Solomon Islands campaign, participating in the Battles of the Eastern Solomons and the Santa Cruz Islands. Kinkaid was placed in charge of the North Pacific Force in January 1943 and commanded the operations that regained control of the Aleutian Islands. He was promoted to vice admiral in June 1943.
In November 1943, Kinkaid became Commander Allied Naval Forces South West Pacific Area, and commander of the Seventh Fleet, directing U.S. and Royal Australian Navy forces supporting the New Guinea campaign. During the Battle of the Surigao Strait, he commanded the Allied ships in the last naval battle between battleships in history. Following the demise of Japanese naval power in the region, the Allied navies supported the campaigns in the Philippines and Borneo. Kinkaid was promoted to admiral on 3 April 1945. After the Pacific War ended in August 1945, the Seventh Fleet assisted in operations on the Korean and China coasts. Admiral Kinkaid was Commander Eastern Sea Frontier and the Sixteenth Fleet from 1946 until his retirement in May 1950. He was a member of the National Security Training Commission for much of the rest of the decade. He also served with the American Battle Monuments Commission for 15 years.
Thomas Cassin Kinkaid was born in Hanover, New Hampshire, on 3 April 1888, the second child and only son of Thomas Wright Kinkaid, a naval officer, and his wife Virginia Lee née Cassin. At the time, Thomas Wright Kinkaid was on leave from the U.S. Navy and employed at the New Hampshire College of Agriculture and the Mechanic Arts. When Thomas was only a year old, his father was posted to USS Pinta, and the family moved to Sitka, Alaska, where a third child, Dorothy, was born in 1890. Over the next few years the family successively moved to Philadelphia, Pennsylvania; Norfolk, Virginia; Annapolis, Maryland, and Georgetown, Washington, D.C.
Thomas attended Western High School for three years before entering a U.S. Naval Academy preparatory school. He sought and secured an appointment to Annapolis from President Theodore Roosevelt, and was asked to take the admission examination. The Navy was undergoing a period of expansion, and the intake of midshipmen was double that of two years earlier. Of the 350 who took the examination, 283 were admitted. The class was the largest since the Academy had opened in 1845.
Kinkaid was admitted to Annapolis as a midshipman in July 1904. His instructors included four future Chiefs of Naval Operations: William S. Benson, William V. Pratt, William D. Leahy and Ernest J. King. In 1905 he took an instructional cruise on USS Nevada. He also spent six weeks on USS Hartford, his only experience of a warship under sail. In subsequent years, his training cruises were on USS Newark and USS Arkansas which, while much newer, were by this time also obsolete. He participated in sports, particularly in rowing, earning a seat in the Academy's eight-oar racing shell. He graduated on 5 June 1908, ranked 136th in his class of 201.
Kinkaid's first posting was to San Francisco where he joined the crew of the battleship USS Nebraska, part of the Great White Fleet. During the next year, he circumnavigated the globe with the fleet, visiting New Zealand and Australia. The fleet returned to its home port of Norfolk, Virginia in February 1909. In 1910, Kinkaid took his examinations for the rank of ensign but failed navigation. While his classmates were promoted in June 1910, Kinkaid remained a midshipman, pending the result of a makeup examination in December 1910. In July, he developed pleurisy and was hospitalized in New York, New York, before being sent to Annapolis to recuperate. At the time, his father was in charge of the Naval Engineering Experiment Station there, which allowed Kinkaid to stay with his parents while studying for his navigation examination. In October, he was posted to the battleship USS Minnesota whose skipper, Commander William Sims, an Annapolis classmate of his father's, encouraged Kinkaid's early interest in gunnery. Kinkaid passed his navigation examination on 7 December and was promoted to ensign on 14 February 1911, backdated to 6 June 1910. While still at Annapolis, Kinkaid met Helen Sherburne Ross (1892–1980), the daughter of a Philadelphia businessman. The two were married on 24 April 1911 in the Silver Chapel of St. Mark's Episcopal Church in Philadelphia in a ceremony attended by a small number of guests. Their marriage produced no children. They enjoyed playing contract bridge and golf, and Helen was the women's golf champion for the District of Columbia in 1921 and 1922.
In 1913, Kinkaid, now a lieutenant (junior grade), commenced a course in ordnance at the Naval Academy Postgraduate School. This consisted of four months of classroom instruction followed by tours with the leading naval ordnance manufacturers, and concluded with a tour of duty at the Indian Head Naval Proving Ground. Students had to commit to remain in the Navy for at least eight years. After completing the four months in the classroom at Annapolis, Kinkaid commenced a three-month assignment at Midvale Steel, but this was interrupted after two months by the United States occupation of Veracruz. Kinkaid was ordered to report to the gunboat USS Machias for duty in the Caribbean, during which the ship participated in the 1916 United States occupation of the Dominican Republic. Kinkaid came under fire for the first time when the ship was fired upon from ashore. Machias replied with its machine guns. When one jammed, Kinkaid exposed himself to fire to assist in clearing the weapon. He fired it in response to gunfire against the ship. Machias returned home in December, and in February Kinkaid resumed his ordnance studies and went to Bausch & Lomb in Rochester, New York, where he studied the manufacture of spotting and fire control systems. In March he reported to the Washington Navy Yard, where he wrote a pamphlet on fire control. He also created a design for a human torpedo, but the Bureau of Ordnance decided that his concept was unsound. He completed his ordnance studies with tours at Bethlehem Steel, the Indian Head Naval Proving Ground and the Sperry Gyroscope Company in Brooklyn.
