World War II was a global war that spanned from 1939 to 1945. The war pitted the Allies and the Axis power in the deadliest war in history, and was responsible for the deaths of over 70 million people.
World War II's Eastern Front was the most brutal war in human history. Historian Samuel Mitchum outlines this contrast vividly — towards the end of the war, when any rational Nazi soldier or officer knew they were going to lose, many would readily surrender to the Allied Forces on the Western Front.
The casualties in World War II were much higher. Over 15 million died in battle — nearly double the number from World War I — and 25 million were wounded. Additionally, World War II resulted in over 45 million civilian deaths.
The First World War was the first time that the psychological trauma of warfare was formally recognised both by doctors and society at large. The condition became known as 'shell shock'.
World War II was the biggest and deadliest war in history, involving more than 30 countries. Sparked by the 1939 Nazi invasion of Poland, the war dragged on for six bloody years until the Allies defeated the Axis powers of Nazi Germany, Japan and Italy in 1945.
The three bloodiest conflicts have been American Civil War (1861–1865), World War I (1917–1918), and World War II (1941–45).
The heaviest loss of life for a single day occurred on July 1, 1916, during the Battle of the Somme, when the British Army suffered 57,470 casualties.
The Anglo-Zanzibar War was a military conflict fought between the United Kingdom and the Zanzibar Sultanate on 27 August 1896. The conflict lasted between 38 and 45 minutes, marking it as the shortest recorded war in history.
On 22 June 1941 Germany invaded the Soviet Union. Codenamed Operation Barbarossa, it was the largest military operation in history, involving more than 3 million Axis troops and 3,500 tanks.
A total of 4,414 Allied troops were killed on D-Day itself, including 2,501 Americans. More than 5,000 were wounded. In the ensuing Battle of Normandy, 73,000 Allied forces were killed and 153,000 wounded.
Battle of Antietam breaks out
Beginning early on the morning of September 17, 1862, Confederate and Union troops in the Civil War clash near Maryland's Antietam Creek in the bloodiest single day in American military history.
The longest war in history is believed to be the Reconquista (Spanish for Reconquest), with a duration of 781 years.
Abstract. Throughout America's first 145 years of war, far more of the country's military personnel perished from infectious diseases than from enemy action.
SS-Obersturmbannfuhrer Otto Skorzeny was one of the most celebrated and feared commandos of World War II. Daring operations such as the rescue of Italian fascist dictator Benito Mussolini and missions behind enemy lines during the Battle of the Bulge made him known as "the most dangerous man in Europe."
Disease was endemic in armies, and in fact killed more fighters than did the enemy. Disease imposed a serious limitation on the size of armies, and on the length of time they could be kept in the field.
World War II (1938-1945) – With a death toll between 40 and 85 million, the Second World War was the deadliest and worst war in history. Experts estimate with such a high death toll, about three percent of the world's population in 1940 died.
The Civil War was the deadliest war in American history. Altogether, over 600,000 died in the conflict, more than World War I and World War II combined. A soldier was 13 times more likely to die in the Civil War than in the Vietnam War.
The Axis powers (Nazi Germany, Fascist Italy, and Imperial Japan) were some of the most systematic perpetrators of war crimes in modern history.
The deadliest and most destructive war in human history claimed between 40 and 50 million lives, displaced tens of millions of people, and cost more than $1 trillion to prosecute. The financial cost to the United States alone was more than $341 billion (approximately $4.8 trillion when adjusted for inflation).
Horrors of war
In Germany's 49 largest cities, nearly 40 percent of homes were seriously damaged or destroyed. In the western Soviet Union, the destruction was even greater. Nearly 40 million European souls perished from war-related causes between 1939 and 1945, more than half of them noncombatants.
