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.
Canadian women in the World Wars
One of the greatest consequences of the First World War was the number of lives lost, missing, and wounded throughout the entirety of the battles. The Allied and Central powers felt immense casualties and losses with 22,447,500 and 16,403,000 (MIA, KIA, WIA), respectively. Nurses faced this reality throughout the war and even on rare instances, Canadian nurses lost their lives while on duty. The most prominent cases of this was the death of four nursing sisters on May 19, 1918, during the bombing raid on No. 1 Canadian General Hospital at Étaples, France, and the death of 14 nursing sisters and over 200 other service personnel on June 27, 1918, when the HMHS Llandovery Castle was sunk by the U-86 The HMHS Llandovery Castle was one of five Canadian hospital ships that served in the First World War. In total, 234 lives were lost with only 24 survivors. The sinking of the HMHS Llandovery Castle was one of the most significant Canadian naval disasters of the First World War, in terms of the overall death toll. By the end of the war, 47 Canadian nurses lost their lives while on active duty, victims of enemy attack or disease contracted from patients Overall, Canadian nurses dealt with the realities of war and were key assets to the Canadian military and Allied forces.
