Major battles are significant military engagements that often determine the outcome of wars. These confrontations involve large forces and strategic planning, with each side aiming to gain control over territory or achieve specific objectives. Examples include the Battle of Gettysburg during the American Civil War and the Battle of Stalingrad in World War II. The results of major battles can lead to shifts in power, influence public opinion, and impact the morale of troops and civilians. They are often studied for their tactics and strategies, such as the use of artillery, infantry, and cavalry, which can provide insights into military history and leadership.
