Although the United States has been in a number of so-called wars, Congress last used its power to declare war in 1942, according to the archives of the House of Representatives. That declaration was part of a series at the start of World War II. The other well-known congressional actions were for World War I and the War of 1812.
World War II was, without a question, the largest war in history, in terms of the scope of nations involved, the wide geography of where battles were fought, and the use of ground, air and naval weapons.
Many of the battles in World War II were conflicts between the Soviet Union, one of the Allied powers, and Nazi Germany, the main Axis power. These battles were characterized by the size of military resources involved and the significant civilian population loss.
The fog of war always complicates exact casualty totals. The estimates are the result of historians patching together primary documents over many years.
24/7 Wall St. has chosen the largest battle of World War II based on the number of casualties, which includes deaths and wounded. As part of our evaluation, we included civilian casualties.
