Battlefield

It is commonly understood to be limited to the point of contact between opposing forces, though battles may involve troops covering broad geographic areas.

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.

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 1820s, General Joseph Rogiat, of Napoleon Bonaparte's Grande Armée, spoke at great length of the circumstances that make for a good battlefield.

He mentions the high ground as a means of observing the enemy, and concealing friendly forces;[5] while this has been mitigated by aerial reconnaissance, improved communication (field telephonesradio,and indirect fire, it remains important.

Rogniat describes a "disadvantageous field of battle" as one: which is everywhere seen and commanded from heights within cannon and musket shot, and which is encumbered with marshes, rivers, ravines, and defiles of every kind.

Suppose that a position, for instance, offers to the defenders a field of battle well situated, but admitting of easy access upon all points; the assailants, finding no obstacle to their deployment for the contest, will be able to force it in a tolerably short time.

In general, the best positions are those, the flanks of which are inaccessible, and which command from their front a gently inclined ground, favourable for attack as well as defence; farther, if the lines lean on villages and woods, each of which forms, by its saliency, a sort of defensive bastion, the army becomes almost impregnable, without being reduced to inaction.

[5] During World War I, for instance, the An Nafud behind Aqaba seemed impassible, until a force of Arab rebels led by T. E. Lawrence successfully crossed it to capture the town.

In World War II, the Pripyat Marsh was an obstacle to vehicles, and the Red Army successfully employed cavalry there specifically because of that, while in North Africa, the Qattara Depression was used as an "anchor" for a defensive line.

Even a seemingly open field, such as that faced by George Pickett at Gettysburg, was broken by fences which had to be climbed—while his division was constantly exposed to fire from the moment it left the trees.

On modern battlefields, introducing obstacles to slow an advance has risen to an art form: everything from anti-tank ditches to barbed wire to dragon's teeth to improvised devices, have been employed, in addition to minefields.

Mardonius illustrated the problem for the Ancient Greeks, whose phalanges were ill-suited for combat except on level ground without trees, watercourses, ditches, or other obstacles that might break up its files,[6] a perfection rarely obtained.

The adoption of chariots makes flat, open battlefields desirable, and larger fields than for infantry alone, as well as offering opportunities to engage an enemy sooner.

The arrival of aerial reconnaissance has been credited with the development of trench warfare, while the combination of high explosives in ammunition and hydraulic recoil mechanisms in artillery, added to aircraft observation, made its subsequent spread necessary, and contributed to the stalemate of WW1.

As much as technology has changed, terrain still cannot be ignored, because it not only affects movement on the battlefield, but movement to and from it, and logistics are critical: a battlefield, in the industrial age, may be a railway line or a highway As technology grows more sophisticated, the length of the "tail", upon which the troops at the front depend, gets longer, and the number of places a battle can be decided (beyond the immediate point of contact) grows.

With respect to the seizure of property, it has been noted that in ancient times it was understood that a prevailing enemy was free to take whatever was left on the battlefield by a fleeing enemy—weapons, armor, equipment, food, treasure—although, customarily, "capture of booty may take place some distance from the battlefield; it may transpire a few days after the battle, and it may even occur in the total absence of any pitched battle".

In particular, the battlefields and positions in the Alps from World War I, which were often exposed, were only partially cleared and fatal accidents continue to happen because mountaineers and climbers collect ammunition.

It was common among the Ancient Greeks and Romans to raise a trophy on the field of battle, initially of arms stripped from the defeated enemy.
