Organised by the Royal Guernsey Light Infantry Charitable Trust, the students - all of whom are visiting Guernsey for the first time - spent time at the RGLI museum at Castle Cornet yesterday as part of a wider tour of St Peter Port, which included trips to Hauteville House, Town Church, and the Sunken Gardens.
They finished their day off with fish and chips at Cobo.
The students are staying with host families as part of an exchange with local students from Blanchelande College and, for the first time, St Sampson's High School, who will visit Masnieres in June.
The link between Guernsey and Masnieres stretches back to late 1917, when more than 400 islanders were reportedly killed as the RGLI held off a counter attack from German forces in Masnieres during the First World War.
In recent years the RGLI has undertaken considerable work to develop diplomatic relations with Masnieres.
The town was twinned with St Peter Port in 2019, while an annual RGLI motorcycle ride to Masnieres forms part of the memorial tributes to the events of the First World War.
RGLI trustee Yvonne Wainwright said this was the third year students from Masnieres had made the visit to Guernsey.
She said they had all been interested in learning about the RGLI during their visit to Castle Cornet, which waved a French flag in tribute to their attendance.
'It's important to keep the memory of what happened alive, especially among the younger generation,' she said.
'The men of the RGLI sacrificed so much at Masnieres, their deaths had a huge social impact on Guernsey.'
Masnieres student Camille Lepine, 13, said she had found Guernsey to be 'really beautiful'.
'The family I'm staying with has been really kind and caring.'
She will be returning to the island in May for the 80th anniversary of the Liberation, as part of a small Masnieres delegation.
'I know it's the 80th anniversary, but I don't know more than this, so I would like to learn more before I come.'
Fellow student Louka Tantant, 15, said he had also enjoyed his stay with his host family.
'The food is good, and I've played a lot of video games.'
The students will have tea with Lt-Governor Lt General Richard Cripwell at Government House and visit Herm as part of their activities for the rest of the week.
