Percy Black and Harry Murray were extraordinary men who made enormous contributions to the Anzac tradition. In their mid-thirties and working in the Australian bush when war was declared in 1914, they were quick to enlist and were placed in the same machine gun section of the newly formed 16th battalion. Their courage and natural ability took both men to high rank and earned them several awards for gallantry. Vividly and authoritatively told, No Ordinary Determination is the true story of two great soldiers of the Anzac legend.
