Established after World War I by the Royal Australian Navy, the Coast Watchers were a loose organisation of several hundred European settlers, missionaries, patrol officers and planters living in British and Australian Pacific Island territories whose job it was to observe and report on the enemy. They were mostly all unpaid volunteers whose job it was simply to observe and report on foreign shipping and aeroplane movements. It was never envisaged that the Coast Watchers would do any fighting, nor operate inside enemy-occupied territory.

On 31st October 1917, as the day's light faded, the Australian Light Horse charged against their enemy. Eight hundred men and horses galloped four miles across open country, towards the artillery, rifles and machine guns of the Turks occupying the seemingly unassailable town of Beersheba. What happened in the next hour changed the course of history. This brave battle and the extraordinary adventures that led to it are brought vividly to life by Australia's greatest storyteller, Peter FitzSimons.

Soon after the declaration of war on Japan, a secret military reconnaissance unit was established, based on the British Special Operations Executive (known as SOE) and called the Inter-allied Services Department. The unit was tasked with the role to "obtain and report information of the enemy...weaken the enemy by sabotage and destruction of morale and to lend aid and assistance to local efforts to the same end in enemy occupied territories."

When the Second World War broke out in September 1939, the British asked Australia for help. With some misgivings, the Australian government sent five destroyers to beef up the British Royal Navy in the Mediterranean. HMAS Vendetta, Vampire, Voyager, Stuart and Waterhen were old ships, small with worn-out engines. Their crews used to joke they were held together by string and chewing gum; when the Nazi propaganda minister Josef Goebbels heard of them, he sneered that they were a load of scrap iron.

It was the evening of 16 May 1943. Nineteen modified Lancaster bombers from 617 Squadron RAF, under the command of youthful Wing Commander Guy Gibson, roared into the night sky from their Lincolnshire base. They were on a top-secret Bomber Command mission, codenamed Operation Chastise, now regarded as one of the most dangerous and audacious bombing raids of World War II - an attack on the formidable, well-defended dams of Germany’s Ruhr Valley. Slung beneath the belly of each aircraft was one of the war’s greatest secrets - a bouncing bomb.
