Syndemic
The worst of the 20th century influenza pandemics was the 1918 pandemic, where between 20-40 percent of the world’s population became ill between 40-100 million people died. More people died of the so-called Spanish flu (caused by the H1N1 viral strain) pandemic in the single year of 1918 than during all four-years of the Black Death. The pandemic had devastating effects as disease spread along trade and shipping routes and other corridors of human movement until it had circled the globe. InIndia, the mortality rate reached 50 per 1,000 population. Arriving during the closing phase of the World War I, the pandemic impacted mobilized national armies. Half of U.S. soldiers who died in the "Great War," for example, were victims of influenza. It is estimated that almost ¾ of a million Americans died during the pandemic. In part, the death toll during the pandemic was caused by viral pneumonia characterized by extensive bleeding in the lungs resulting in suffocation. Many victims died within 48 hours of the appearance of the first symptom. It was not uncommon for people who appeared to be quite healthy in the morning to have died by sunset. Among those who survived the first several days, however, many died of secondary bacterial pneumonia. It has been argued that countless numbers of those who expired quickly from the disease were co-infected with tuberculosis, which would explain the notable plummet in TB cases after 1918.
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.
