Australia Remembers: Gallipoli 100

World War II was the sum of battles waged: strategies that succeeded or failed, changing the course of the war. Some were the result of careful planning leading to decisive victory, like the Allied assault on Rommel's forces at El Alamein. Others would defy carefully laid plans. From Pearl Harbor, where Japan's attack on US naval capacity instead galvanised America to join the war, to Okinawa, where the Allied victory came at such a cost they would turn to a new strategy in Japan, the atomic bomb. Each battle another domino tipping, leading the world inexorably towards victory or surrender.

Little more than 20 years after the guns fell silent, they roar back into life. Hitler annexes all of Czechoslovakia, Britain and France respond with promises to Poland and Stalin, and Hitler, with unexpected and pragmatic hypocrisy, signs a pact. Then, Hitler moves on Poland and the fighting starts in Europe. China and Japan are already fighting. The curtain goes up on what will become the world's first truly global and total war.

In what could turn out to be the largest murder case on British soil. Forensic archaeologist, Caroline Sturdy Colls, goes in search of a Nazi SS camp constructed in secrecy on the British Channel island of Alderney during World War II. Years of research and forensic investigation have led Sturdy Colls to examine remnants of concentration and labour camps on the quiet island, and to official SS archives in Germany, where clues emerge that lead Caroline to suspect that Alderney was the scene of Nazi mass murders. However, when local officials attempt to stop the investigation, the search for the final resting place of the victims is imperilled. Sturdy Colls led the forensic team that discovered the gas chambers at Treblinka in 2013, but now they face their toughest challenge to date this time much closer to home. Shrouded in a decades-long conspiracy of silence amid attempts by local authorities to prevent examination and the search for the missing victims of Nazi atrocities, the team must turn to state-of-the-art technology to get the answers they seek. After much discussion, compromise and stonewalling, their final discoveries, made in spite of vigourous protests by the Alderney government, are chilling.
