World War I casualties
Casualty statistics for World War I vary to a great extent; estimates of total deaths range from 9 million to over 15 million. Military casualties reported in official sources list deaths due to all causes, including an estimated 7 to 8 million combat related deaths (killed or died of wounds) and another two to three million military deaths caused by accidents, disease and deaths while prisoners of war. Official government reports listing casualty statistics were published by the United States and Great Britain. These secondary sources published during the 1920s, are the source of the statistics in reference works listing casualties in World War I. This article summarizes the casualty statistics published in the official government reports of the United States and Great Britain as well as France, Italy, Belgium, Germany, Austria and Russia. More recently the research of the Commonwealth War Graves Commission (CWGC) has revised the military casualty statistics of the UK and its allies; they include in their listing of military war dead personnel outside of combat theaters and civilians recruited from Africa, the Middle East and China who provided logistical and service support in combat theaters. The casualties of these support personnel recruited outside of Europe were previously not included with British war dead, however the casualties of the Labour Corps recruited from the British Isles were included in the rolls of British war dead published in 1921. The methodology used by each nation to record and classify casualties was not uniform, a general caveat regarding casualty figures is that they cannot be considered comparable in all cases.
List of First World War Victoria Cross recipients
On 1 July 1916, the first day of the Battle of the Somme, the British Army endured the bloodiest day in its history, suffering 57,470 casualties and 19,240 dead; nine Victoria Crosses were awarded for action on that day. Most of the casualties occurred in the first hour of the attack. The entire Somme offensive cost the British Army almost half a million men. The war was not just fought on land; the First World War saw major naval battles as well as the first large-scale use of military aircraft. The war at sea was mainly characterised by the efforts of the Allied Powers in blockading the Central Powers by sea. In return, the Central Powers attempted to break that blockade and establish an effective blockade of the British Isles and France with U-boats and raiders. The largest naval battle of the First World War was the Battle of Jutland which was the only full-scale clash of battleships in that war. Four Victoria Crosses were awarded for action at Jutland. The war in the air saw 19 VCs being awarded to airmen. The First World War saw significant interest in flying aces, including the German Manfred von Richthofen—also known as The Red Baron—as well as British aces such as Albert Ball, Mick Mannock and Billy Bishop, who were all Victoria Cross recipients. Hostilities ended on 11 November 1918 with the signing of the Armistice Treaty in the Compiègne Forest, but the war was not officially over until the various peace treaties were signed in 1919. By the war's end, four major imperial powers – Germany, Russia, Austria-Hungary, and the Ottoman Empire—had been militarily and politically defeated, and the latter two ceased to exist as autonomous entities. Of the 60 million European soldiers who were mobilised from 1914–1918, 8 million were killed, 7 million were permanently disabled, and 15 million were seriously injured.
