Fourteen months after the September 11 attacks shook the world, Martin 'Jock' Wallace was awarded the nation's third-highest military honour for bravery - the Medal for Gallantry - for his actions in the war against terror in south-eastern Afghanistan. At the age of thirty-two, working as a signalman the elite Special Air Service Regiment, Wallace's courage under fire during Operation Anaconda helped save the lives of eighty American soldiers and two Australians (including himself), who were ambushed by up to 1000 al-Qaeda terrorists and Taliban hard-liners in a life-and-death battle. 18 Hours is the true story of a modern-day Australian war hero - a powerful, action filled anatomy of his eighteen-hour-long battle against the world's most dangerous terrorist group, al-Qaeda, in their last stronghold in Afghanistan.
