The Battle of the Somme was the biggest battle in World War I, which took place from July 19 16 to July 1 Day1Year1October 65438. In order to break through the German lines and repel them to the French-German border, Britain and France fought in the Somme region of northern France. The casualties on both sides were 1.3 million, which was the worst positional warfare in World War I and the first time that tanks were put into actual combat in human history.

The Battle of Stalingrad was a turning point in the Eastern Front of World War II. Judging from the number of casualties, this is also the bloodiest battle in modern history. It is estimated that the number of casualties on both sides is about 2 million, and the number of participants in this battle is more than other battles in history, and it is more famous for the casualties caused by ignoring the difference between the military and the people. The Battle of Stalingrad was the first large-scale defeat of Germany in World War II, which made the possibility of German victory on the Eastern Front completely disappear and the strategic dominance changed hands to the Soviet Union. The German Army Group A attacking the North Caucasus retreated to Rostov-on-Don.

Comparing the casualties of the two battles, the battle with the largest scale and the largest number of casualties in human history should be the Battle of Stalingrad.
