Friday 1 July 2016 marks the centenary of the beginning of the Battle of the Somme, the biggest conflict seen on the Western Front during World War I. Here are some of the most arresting photos from the war. Contains graphic images.
John "Jack" Simpson Kirkpatrick (centre of picture) who served under the name John Simpson, was a stretcher bearer with the Australian and New Zealand Army Corps (ANZAC) during the Gallipoli Campaign. After landing at Anzac Cove on 25 April 1915, he obtained a donkey and began carrying wounded soldiers from the frontline to the beach, for evacuation. He did this for three and a half weeks, often under fire, until he was killed. Simpson and his Donkey are a key part of the "Anzac legend".
