First World War authority Malcolm Baxter is helping to ensure the youngsters of today do not forget the sacrifices made by their great-grandparents.
Malcolm gives regular talks on the old Machine Gun Corps which was based at Belton Park during the First World War.
He said: “I lived in Queensway when I was young and my dad used to tell me about the Machine Gun Corps being just across the road in Belton Park so I got interested from there.
“My grandfather served in the Lincolnshire Regiment and I used to go on quite a few battlefield trips to places like Gallipoli and the Somme.”
Mr Baxter also works as a caretaker at Belmont Community Primary School and recently put on a talk there for the children.
He said: “I took in some gas masks - from baby to adult - and bells and whistles and they were very, very interested.
“ I also told them about some of the bombings in Grantham because both my mum and dad lived in streets that were bombed.”
