Students from the Oasis Academy might have unwittingly changed the outcome of the First World War.
When they recreated the 1914 Christmas Day football match in No Man's Land Germany ended up winning.
PE teacher Wesley Carlow said: "The game ended 4-2 to Germany but it was a very good match.
"Germany went into an early two-goal lead but England pulled it back to equalise before Germany won with two last-minute goals. The boys and girls really got into the spirit of things."
He said the teams fielded boys and girls because if the match had been played today both sexes would be allowed on the front line. Both teams wore army uniforms from the different sides.
The Christmas Truce of 1914 is often celebrated as a symbolic moment of peace in an otherwise devastatingly violent war.
It happened after the indecisive result of the First Battle of Ypres.
The school's football match on Friday was part of the Academy's Inspire event to mark the 100th anniversary of the end of the First World War.
Students from all of Sheppey's schools had been invited to entertain guests in the packed Sheerness campus theatre with songs, dances and poetry before a "peacefields" tree was planted at the Minster campus.
Mayor of Swale Cllr Samuel Koffie-Williams told guests: "We should all leave here today in peace."
The event was masterminded by the academy's community leader Paul Murray.
