Battlefield

A battlefield, battleground, or field of battle is the location of a present or historic battle involving ground warfare. It is commonly understood to be limited to the point of contact between opposing forces, though battles may involve troops covering broad geographic areas. Although the term implies that battles are typically fought in a field – an open stretch of level ground – it applies to any type of terrain on which a battle is fought. The term can also have legal significance, and battlefields may have substantial historical and cultural value—the battlefield has been described as "a place where ideals and loyalties are put to the test". Various acts and treaties restrict certain belligerent conduct to an identified battlefield. Other legal regimes promote the preservation of certain battlefields as sites of historic importance.

Modern military theory and doctrine has, with technological advances in warfare, evolved the understanding of a battlefield from one defined by terrain to a more multifaceted perception of all of the factors affecting the conduct of a battle and is conceptualised as the battlespace.

The occurrence of a battle at a particular location may be entirely accidental, if an encounter between hostile forces occurs with neither side having expected the encounter. Typically, however, the location is chosen deliberately, either by agreement of the two sides or, more commonly, by the commander of one side, who attempts to either initiate an attack on terrain favorable to the attack, or position forces on ground favorable to defense, if anticipating an attack.

Although many battlefields arise in the course of military operations, there have been a number of occasions where formal conventions have ordained the nature and site of the battlefield. It has been suggested, on the basis of anthropological research, that ritual warfare involving battles on traditional "fighting grounds", bound by rules to minimise casualties, may have been common among early societies.

In the European Middle Ages, formal pre-arrangement of a battlefield occasionally occurred. The Vikings had the concept of the "hazelled field", where an agreed site was marked out with hazel rods in advance of the battle.

Formal arrangements by armies to meet one another on a certain day and date were a feature of Western Medieval warfare, often related to the conventions of siege warfare. This arrangement was known as a journée. Conventionally, the battlefield had to be considered a fair one, not greatly advantaging one side or the other. Arrangements could be very specific about where the battle should take place. For example, at the siege of Grancey in 1434, it was agreed that the armies would meet at "the place above Guiot Rigoigne's house on the right side towards Sentenorges, where there are two trees".

In a pitched battle, although the battlefield is not formally agreed upon, either side can choose to withdraw rather than engaging in the battle. The occurrence of the battle therefore generally reflects the belief by both sides that the battlefield and other circumstances are advantageous for their side.

Some locations are chosen for certain features giving advantage to one side or another.
