A service has been held to commemorate the bravery of a soldier who died while saving his men during a training exercise in the First World War.

A plaque was unveiled at Port Laing beach in North Queensferry in Fife on Monday, 100 years after the death of Lieutenant George Cyril Olguin Paton of the Royal Scots Fusiliers.

The 21-year-old was in charge of a group of men practising grenade throwing near Port Laing on June 20, 1916, when one was thrown near the group.

Fearing the weapon would kill the men, Lt Paton ran forward to try to throw the grenade to a safe distance. He reached it but it exploded, killing him instantly.

Lt Paton was buried in nearby Inverkeithing but his bravery was never officially recognised.

Members of the North Queensferry Heritage Trust stumbled across his story online while researching the area's war veterans.

Trust member Colin Bain said he felt Lt Paton's bravery should be marked.

Mr Bain said: "We started looking into it and found that he had been killed in this heroic but tragic circumstances.

"His bravery was such that nowadays he would have been recognised with a posthumous medal. There was no provision available in those days."

Relatives, members of 2nd Battalion Royal Regiment of Scotland and the Regimental Association, pupils from North Queensferry Primary and residents gathered for the service on Monday afternoon.

A relative unveiled the small plaque in Lt Paton's honour.

Lt Paton, who was born in Argentina to a Scottish father, was one of more than 5000 men from the country who joined the British forces in the First World War.
