He enlisted in the US Army in January of 1951, shortly before his 20th birthday, and deployed to Korea with the 223 Infantry Regiment that June.
On June 14, 1952, Corporal Speicher earned a Congressional Medal of Honor, while his unit was attempting to take an important sector. His unit was pinned down by machine-gun fire and, while wounded, Corporal Speicher left his cover and charged the machine-gun embankment, receiving additional wounds in the process. He disabled the nest by killing two enemy fighters with his rifle and one with his bayonet. Corporal Speicher crested the hill with his unit before succumbing to his wounds.
Corporal Clifton Speicher rests in the Beam Cemetery in Jennerstown Pennsylvania.
