William H. Rupertus

William H. Rupertus was a senior officer in the United States Marine Corps who rose to the rank of major general during World War II. He is best known for his command of the famed 1st Marine Division during several critical campaigns in the Pacific War. His leadership during the intense fighting on Cape Gloucester and the costly Battle of Peleliu cemented his reputation as a determined combat commander.

Early life and education

William Henry Rupertus was born on November 14, 1889, in Washington, D.C.. He attended Western High School before receiving an appointment to the United States Naval Academy in Annapolis, Maryland. He graduated and was commissioned as a second lieutenant in the United States Marine Corps in 1913. His early training included instruction at the Marine Corps Schools in Quantico, Virginia, which laid the foundation for his tactical expertise.

Military career

Following his commissioning, Rupertus served in various posts, including sea duty aboard the USS *Wyoming*. His early career was shaped by expeditionary service during the Banana Wars, particularly the United States occupation of Haiti. He later served as an instructor at the Marine Corps Officer Candidates School and held important staff positions, including a tour as the Director of the Division of Operations and Training at Headquarters Marine Corps. He also commanded the ceremonial Marine Barracks, Washington, D.C., showcasing his versatility as an officer.

World War II service

At the outbreak of World War II, Rupertus was serving as Assistant Commandant of the Marine Corps Schools. In 1943, he was promoted to major general and assumed command of the 1st Marine Division, succeeding Alexander Vandegrift. He led the division in the latter stages of the Battle of Guadalcanal. His most significant command came during Operation Cartwheel, where he directed the Battle of Cape Gloucester in New Britain, securing a vital Allied airfield. His final and most controversial battle was the Battle of Peleliu in the Palau Islands, a campaign marked by extremely high casualties against fierce resistance from the Imperial Japanese Army.

Death and legacy

Exhausted from the prolonged combat on Peleliu, Rupertus returned to the United States and was assigned to command the Marine Corps Base San Diego. He suffered a fatal heart attack on March 25, 1945, at his quarters in Quantico, Virginia, and was buried with full military honors at Arlington National Cemetery. His legacy includes the "Rupertus' Prayer" or "My Rifle," a creed often attributed to him that emphasizes the bond between a Marine and their weapon. The USS *Rupertus*, a Gearing-class destroyer, was named in his honor.

Awards and decorations

Major General Rupertus's personal decorations include the Navy Distinguished Service Medal for his leadership of the 1st Marine Division, the Legion of Merit for his service in the South Pacific Area, and the Purple Heart. He was also entitled to wear the Marine Corps Expeditionary Medal for his service in Haiti, the World War I Victory Medal, the American Defense Service Medal, the Asiatic-Pacific Campaign Medal with three service stars, and the World War II Victory Medal.
