In the northern French town of Le Quesnoy, the names of local streets and landmarks serve notice of a debt to New Zealand. In the final week of World War I Kiwi soldiers freed Le Quesnoy from its German occupiers — thanks partly to a 'magic' ladder, daringly used to scale the town’s 90-foot-high ramparts. Director David Blyth heads to France for the anniversary of Le Quesnoy’s liberation, following the path of one of the liberators: his late grandfather ‘Curly’ Blyth. The doco also includes an interview with Curly, conducted by historian Christopher Pugsley.

Lawrence 'Curly' Blyth volunteered for World War 1 despite being under age. In 1916 his rifle brigade was sent to the Western Front, where he fought for 23 days amongst the mud of the Somme. In the final weeks of WW1 Blyth helped liberate the strategic French town of Le Quesnoy from German forces, later winning a French Legion of Honour for his efforts. In this documentary his grandson, director David Blyth, uses interviews and stock footage to chronicle the times at war of his bossy yet personable grandad, who died in 2001, aged 105.

Harry Varnham was scarred both physically and mentally by his experience of World War One. In this episode of Great War Stories, his family explain why they believe the trauma of war eventually led him to take his own life decades later. Wounded during the Battle of Messines in Belgium, Varnham returned to the front and was seriously wounded again at Le Quesnoy. He was evacuated to London; he was just 19 when his leg was amputated. Back in New Zealand, Varnham married later in life and had two daughters, but he never overcame the mental scars from his time serving in WWI.
