Battle

Generally, a battle is a conceptual component in the hierarchy of combat in warfare between two or more armed forces, or combatants. A war sometimes consists of many battles. Battles generally are well defined in duration, area, and force commitment.

Wars and military campaigns are guided by strategy, whereas battles take place on a level of planning and execution known as operational mobility. German strategist Carl von Clausewitz stated that "the employment of battles ... to achieve the object of war" was the essence of strategy.

Admiral Stahl states in his book ."The Soul of War" - :

"The first battle defines a war, the last it's outcome"
