Australian soldiers look at crane diggin

Australian soldiers look at crane digging up a field on May 5, 2009, in Fromelles, northern France, as forensic experts began to excavate a World War I mass grave at a solemn ceremony to launch the recovery of hundreds of fallen Australian and British troops. Between 250 and 400 the Australians and Britons killed in the Battle of Fromelles are thought to have been buried by German forces, without name tags, in five separate pits in Pheasants Wood. Test digs ordered by the Australian army in 2007 and 2008 revealed human remains, along with buttons from military underwear, in what is thought to be the largest unmarked Allied war grave found since the 1918 Armistice.
