Untold stories of World War I Australian and New Zealand sappers—combat engineers—with extracts from their diaries. The sappers were always in the vanguard, clearing defences, and building bridges, roads and walkways, usually under fire, for the troops who followed. At Gallipoli, strafed by machine guns and targeted by snipers, they dug trenches and tunnels to advance on the Turkish defences. On the Western Front, they burrowed under the German lines to plant massive explosives. In Egypt they demolished a Turkish railway in a day.

This book would be of high interest to people whose forebears served as a Sapper or Australian engineer during World War I.
