William Henry Rupertus
Major General, US Marine Corps
Biography
William Henry Rupertus was born November 14, 1889, in Washington, D.C. Rupertus began his military career immediately after high school, originally intending to serve as a cutter captain in the United States Revenue Cutter Service (the earlier version of the modern Coast Guard). However, his excellent marksmanship led to his being recruited by the Marine Corps, and he accepted a commission in November of 1913. Rupertus served on the Marine Corps rifle team, earning the Distinguished Marksman badge and winning a number of shooting matches.

Rupertus was serving aboard the USS Florida (BB-30) when the United States entered World War I. He was called back to the U.S. to command a detachment of Marines headed for Port-au-Prince, Haiti. Rupertus served in Haiti until after the war, when he was sent to staff officer training and then made Inspector of Target Practice in the Operations and Training Division at Marine Corps Headquarters.

In July 1937, Rupertus was a battalion commander in the 4th Marines when the Japanese attacked Shanghai in the Second Sino-Japanese War.

During World War II, he served as Assistant Division Commander of the 1st Marine Division under Major General Alexander Vandegrift. It was around this time that Rupertus is said to have penned The Rifleman's Creed, with the intent of encouraging expert marksmanship and Marines' trust in their weapons.

Rupertus commanded the Landing Task Force Organization which captured the islands of Tulagi, Gavutu and Tanambogo in the Guadalcanal campaign. After Vandegrift left the division in 1943, Rupertus took command. He led the 1st Marine Division during the Battle of Cape Gloucester and the Battle of Peleliu.

In November 1944, Major General Rupertus became Commandant of the Marine Corps Schools at Quantico, Virginia. The tenure was short, however, as he died of a heart attack just four months later. In 1945, the destroyer USS Rupertus (DD-851) was named in his honor.

The Rifleman's Creed by Major General W. H. Rupertus, USMC
THIS IS MY RIFLE. There are many like it but this one is mine. My rifle is my best friend. It is my life. I must master it as I master my life. My rifle, without me is useless. Without my rifle, I am useless. I must fire my rifle true. I must shoot straighter than any enemy who is trying to kill me. I must shoot him before he shoots me. I will.... My rifle and myself know that what counts in this war is not the rounds we fire, the noise of our burst, nor the smoke we make. We know that it is the hits that count. We will hit... My rifle is human, even as I, because it is my life. Thus, I will learn it as a brother. I will learn its weakness, its strength, its parts, its accessories, its sights and its barrel. I will keep my rifle clean and ready, even as I am clean and ready. We will become part of each other. We will... Before God I swear this creed. My rifle and myself are the defenders of my country. We are the masters of our enemy. We are the saviors of my life. So be it, until victory is America's and there is no enemy, but Peace
