Born in 1831 in Norway, Williams immigrated to the United States and lived in California. He worked as a civilian sailor for nine years before joining the U.S. Navy in New York on January 27, 1862, for a three-year term of service. His enlistment papers record him as being 5 feet 4 inches tall with blue eyes, brown hair, and a "florid" complexion. Following brief assignments to and the receiving ship, Williams was transferred to the newly built, the first ironclad warship of the Union Navy, by March 6, 1862. He served on Monitor as a seaman and quartermaster, a position responsible for navigation of the ship. At the Battle of Hampton Roads on March 9, 1862, Williams stood at the ship's wheel and steered Monitor throughout an engagement with the Confederate ironclad CSS Virginia. This battle represented the first meeting in combat of two ironclad warships. Williams was particularly noted for moving Monitor away from Virginia when the latter attempted to ram Monitor and again when Monitor's Captain John Lorimer Worden was wounded. Shipmate John Driscoll recalled of Williams: "Peter saw more of her than anyone else. He say right into the bore of the gun... Pete says, 'Captain, that is for us,' and rip! she came." For his actions during the battle, Williams was awarded the Medal of Honor a year later on April 3, 1863. He was the only person to receive the Medal of Honor for service on Monitor. Weeks after the battle, Williams was promoted to mate and then to master's mate for his "heroic service" at Hampton Roads. On December 31, 1862, he survived the sinking of Monitor in rough seas. He and fellow quartermaster Richard Anjier were applauded by their captain, Commander John P. Bankhead, for showing "the highest quality of men and seamen" during the incident. Williams entered the commissioned officer ranks on January 10, 1863, with his assignment to as an acting ensign, a position he held through the end of the war. In December 1865, he was placed in command of, a steam tugboat in the West Gulf Blockading Squadron. Williams was honorably discharged from the U.S. Navy on November 9, 1867, after nearly six years of service. Williams is one of the hundreds of Medal of Honor recipients who are considered "lost to history", as his place of burial and other biographical details outside of his naval service are unknown.
