At that time, he was on the Asiatic Station, where, during the Philippine–American War and the Boxer Rebellion in China, he served on and and commanded the gunboat.

Government service and recall

Governor of Puerto Rico

From September 1939 to November 1940, Leahy served as Governor of Puerto Rico after Roosevelt removed Blanton Winship over his role in the Ponce massacre. Leahy oversaw the development of military bases and stations across the island while serving as governor. He took an open stance of not intervening directly in local politics, attempted to understand and respect local customs, and initiated various major public works projects in the island.
While given the unflattering sobriquet Almirante Lija by locals, based on his family name, he was regarded as one of the most lenient American governors of the several who served Puerto Rico in the first half of the 20th century.

Ambassador to France

Leahy was appointed Ambassador to France in 1941 following that country's capitulation to Germany. Leahy relates in his memoir I Was There that "major task was to keep the French on our side in so far as possible". He was recalled in May 1942.
The United States supplied food and medical aid to the Vichy regime and to French North Africa, hoping in return to moderate Vichy collaboration with Germany and to avoid an open Vichy–German alliance in the Mediterranean. American aid proved too little to buy French support over North Africa.

Chief of Staff to the Commander in Chief

After the United States entered World War II, President Roosevelt decided he needed a senior military officer as personal adviser and point of contact with his three service chiefs, Admiral Ernest King of the Navy, General George Marshall of the Army and General Henry Arnold of the Army Air Forces. The service chiefs resisted this move until Marshall suggested that only Leahy would be accepted in this post. On July 6, 1942, Leahy was appointed Chief of Staff to the Commander in Chief, U.S. Army and Navy, the President of the United States. Leahy was also appointed to be the head of the Joint Chiefs of Staff, which would serve as the governing body of the U.S. Armed Forces, with the Chief of Staff of the U.S. Army, the Chief of Naval Operations of the U.S. Navy, which also had jurisdiction over the U.S. Marine Corps and the U.S. Coast Guard, and the Commanding General of the U.S. Army Air Forces also serving as members during World War II.
Leahy spent D-Day, June 6, 1944, in his home town of Hampton, Iowa. This well-publicized "sentimental journey" was part of the deception efforts surrounding the Allied invasion of Europe. The idea was to lull any German agents in Washington, D.C., or elsewhere in the United States into believing that the operation would not take place while such an important officer was out of the capital.
In July 1944, Leahy accompanied President Roosevelt to the Pacific Strategy Conference in Hawaii at which Roosevelt met Admiral Chester Nimitz and General Douglas MacArthur to decide the course of the war in the Pacific theater.
Leahy was promoted to the rank of Fleet Admiral on December 15, 1944, the most senior of the seven men who received five star rank in 1944.
Leahy accompanied President Roosevelt as his personal aide to the Yalta Conference in February 1945. At Yalta Roosevelt met the British Prime Minister Winston Churchill and Soviet leader Joseph Stalin to decide how Europe was to be reorganized after the impending surrender of Germany. Five months later, he went with President Truman to the Potsdam Conference where Truman met with Stalin and the new British Prime Minister Clement Attlee to make decisions about the governance of occupied Germany.

Atomic bomb

According to Truman's Memoirs: Year of Decisions, Leahy had stated in 1945 to President Truman:
Once the bomb was tested, Leahy became strongly opposed to its use in Hiroshima and Nagasaki. In his own memoirs, Leahy wrote:
After mediating between the United States Navy and the Puerto Rican government over the involuntary transfer of part of the islands of Vieques and Culebra to naval authorities, Leahy again retired from the Navy in March 1949, though as an officer with five-star rank, he technically remained on active service. The following year, he published his war memoirs, I Was There.
There is a bilingual book called Las memorias de Leahy: los relatos del almirante William D. Leahy sobre su gobernación de Puerto Rico that lists his diary entries from Puerto Rico in both Spanish and English, which was published by the Luis Muñoz Marín Foundation in 2001.

Personal life

While serving on the, which was based in San Francisco, Leahy met Louise Tennent Harrington, whom he married on 3 February 1904. During Leahy's tenure as Ambassador to France, his wife underwent a hysterectomy which could not be delayed until their pending return to the United States. While recovering in the hospital from the operation, Louise Leahy suffered an embolism and died with Leahy at her side on 21 April 1942. After a service at the St Thomas Episcopal Church, she was buried on 3 June 1942 in Arlington National Cemetery.
William and Louise had children, including a son, William Harrington Leahy, who graduated from the U.S. Naval Academy in 1927. He engaged in pre-World War II naval intelligence. William H. Leahy retired from the U.S. Navy as a 2-star rear admiral in 1961.

Leahy died at the U.S. Naval Hospital in Bethesda, Maryland, July 20, 1959, at the age of eighty-four. He was given an Armed Forces military funeral on July 23, 1959. His body was viewed at the Bethlehem Chapel at the Washington National Cathedral from July 22 noon until noon the following day.
