The 15 Highest Ranking Military Generals and Admirals in American History

Before becoming the first president of the United States, military officer and statesman George Washington was appointed commander in chief of the Continental Army, a rank he held from 1775 until the conclusion of the Revolutionary War in 1783. In 1976, Congress posthumously promoted him to general of the Armies – the highest Army rank possible – for his service as the first commanding general of the U.S. Army.

On July 25, 1866, Congress promoted General Ulysses S. Grant to general of the Army for his command of the Union Army that led to victory in the Civil War. Although the rank carried only four stars at the time, a 1924 ruling determined that the rank was equivalent to the general of the Armies rank held by both George Washington and John J. Pershing.

When Grant became president, he passed the role of general of the Army on to former Union Army General William T. Sherman. Although the rank bears the same name as the modern five-star rank of general of the Army, this post-Civil War era rank was distinct from the modern rank and only awarded to three people between 1866 and 1888.

While in ill health, former Union Army General Philip Sheridan became the last post-Civil War era general of the Army, a position he held for a few months until his death on Aug. 5, 1888. As opposed to the modern five-star general rank, the rank that Sheridan shared with Sherman and Grant could only be held by one officer at a time.

On March 24, 1903, Admiral George Dewey was promoted to admiral of the Navy (retroactive to March 2, 1899) in recognition of his victory at Manilla Bay during the Spanish American War. Dewey remains the only U.S. Navy officer ever awarded this title. Admiral of the Navy is generally considered equivalent to or senior to the five-star rank of fleet admiral.

Army General John J. Pershing was promoted in 1919 to general of the Armies, the most senior rank possible in the U.S. Army, for his leadership in the American Expeditionary Forces during World War I. Although the rank supersedes that of a five-star general, it has yet to be officially assigned six stars.

The first World War II general to be promoted to general of the Army was George C. Marshall, who was already serving as chief of staff of the U.S. Army. He would later become the U.S. secretary of defense and the U.S. secretary of state. Marshall is remembered for facilitating the Allied victory during the war and for his organization of post-war aid to Western Europe.

Known for his leadership in the Pacific theater of World War II, General Douglas MacArthur was the field marshal of the Philippine Army and the military advisor to the commonwealth government of the Philippines. He was promoted to general of the Army on Dec. 18, 1944, and oversaw the Allied occupation of Japan after its surrender in 1945.

During World War II, Dwight D. Eisenhower served as supreme commander of the Allied Expeditionary Force in Europe, leading both the invasion of North Africa (Operation Torch) and the invasion of Normandy (Operation Overlord). He was promoted to general of the Army on Dec. 20, 1944, and is remembered as the architect of D-Day who would later become the 34th president of the United States.

An aviation pioneer, Henry H. Arnold was chief of the U.S. Army Air Corps, then became head of the Army Air Forces during World War II before being promoted to general of the Army. He is the only officer ever to hold five star ranks in two branches of the U.S. Armed Forces as well as the only person to ever hold the position of general of the Air Force, which he gained in 1949.

The first U.S. Navy officer to officially hold a five-star rank, WIlliam D. Leahy was the senior-most military officer on duty during World War II, serving as the chairman of the joint chiefs of staff, and advisor to the president. He became a five-star fleet admiral on Dec. 15, 1944, and was a major decision maker during World War II.

After the Japanese attack on Pearl Harbor, naval officer Ernest King became commander in chief of the United States Fleet. He then served as chief of naval operations during World War II and was second in command under William Leahy. King was promoted to fleet admiral on Dec. 17, 1944, and retired a year later, leaving Chester Nimitz in command.

As a leading authority on submarines, naval officer Chester Nimitz served not only as the commander in chief of the U.S. Pacific Fleet during World War II, but also the commander of all Allied air, land, and sea forces in the Pacific theater. He was promoted to fleet admiral on Dec. 19, 1944, and served as chief of naval operations from 1945 to 1947.

Having commanded a destroyer and an aircraft carrier during World War I, William Halsey Jr. became commander of the South Pacific area during World War II under Fleet Admiral Chester Nimitz. Halsey led Allied forces during the Battle of Guadalcanal and commanded the Third Fleet during the Battle of Leyte Gulf, one of the largest naval battles in history. He became the last officer to be promoted to fleet admiral on Dec. 11, 1945.

Omar Bradley served as the commander of the Twelfth U.S. Army Group – the largest Army formation ever to serve under one field commander – during World War II, then went on to become chief of staff of the U.S. Army before he was promoted to general of the Army after the start of the Korean War. He remains the last individual appointed to a five-star position in the U.S. Armed forces.
