Jerseyman Clarence Ahier was one of many who joined up to fight in the First World War.
He served in the Artillery in some of the bloodiest battles of the war.
And he kept a diary of his experiences, which was recently given to the Societe Jersiaise.
His nephew David Vautier still lives in Jersey, and only came across the diary recently and reads extracts for BBC Jersey.
As the First World War continued, the two sides became deadlocked, dug in, in trenches which stretch from the English Channel to Switzerland.
The war of attrition meant they simply tried to kill each other with bombs, gas and guns without taking any actual land.
The artillery was essential, to keep the enemies heads down, and to break up any attacks. Jerseyman Clarence Ahier was a gunner.
