Cliff Guard was born in Swansea, but went on to become a G.I. in the US Army, and fought in some of the biggest battles of the Second World War. He is now 91 years old and back home.
As we continue our coverage in the lead up to Armistice Day - he told his incredible story to our reporter Tom Sheldrick:
Cliff Guard was born in 1923, and grew up in poverty on the backstreets of Swansea, pinching potatoes from the market to survive the depression of the 1930s.
He joined the merchant navy aged just 15, and was on the Atlantic Convoys, bringing food and other supplies back to Britain at the start of the Second World War.
He was in New York as America joined the war, and signed up to fight in the US Army, after hearing about the damage done by heavy bombing to Swansea.
His comrades called him G.I. Limey, a common North American nickname for Brits.
He describes himself now as "a Welsh American."
His war service included landing on Omaha Beach at D-Day, and liberating two German concentration camps.
He was wounded, and narrowly avoided death, when shrapnel struck his nose at the bloody Battle of the Bulge.
He has been awarded American, French and British war medals.
He says "I don't feel like a hero. I had a job to do, and I did it to the best of my ability."
After the war, he settled in the USA and had children, working as a psychologist, and even in Saudi Arabia.
He then met his second wife Maggie and moved home to Swansea in retirement.
Now 91, he is contributing to a book about his life - and he even says he is eventually going to get round to completing a masters degree.
