Civilian casualty ratio
Some 7 million combatants on both sides are estimated to have died during World War I, along with an estimated 10 million non-combatants, including 6.6 million civilians. The civilian casualty ratio in this estimate would be about 59%. Boris Urlanis notes a lack of data on civilian losses in the Ottoman Empire, but estimates 8.6 million military killed and dead and 6 million civilians killed and dead in the other warring countries. The civilian casualty ratio in this estimate would be about 42%. Most of the civilian fatalities were due to famine, typhus, or Spanish flu rather than combat action. The relatively low ratio of civilian casualties in this war is due to the fact that the front lines on the main battlefront, the Western Front, were static for most of the war, so that civilians were able to avoid the combat zones.
British yeomanry during the First World War
The British yeomanry did not have the same huge casualty lists, common among the infantry regiments. The Queen's Own Worcestershire Hussars with 215 had the highest total dead, while the 1st County of London Yeomanry (Middlesex, Duke of Cambridge's Hussars) only had eight dead. The greatest loss on one day was ninety-three from the Leicestershire Yeomanry on 13 May 1915, during the Second Battle of Ypres. Out of the fifty-four regiments, three had over 200 dead, ten of them over 100 dead, sixteen had fifty or more dead and the remainder less than fifty dead. According to the Commonwealth War Graves Commission the yeomanry regiments total dead during the First World War was 3,867 men,
among that total was Brigadier-General Wight-Boycott of the Warwickshire Yeomanry, and nineteen lieutenant-colonels some while serving with other units.
