Night combat


Night combat is combat that occurs during the hours of darkness. It is distinguished from daytime combat by lower visibility and its reversed relation to the Circadian cycle. Typically combat at night is favorable to the attacker, with offensive tactics being focused on exploiting the advantages to maximum effect. Defensive night tactics mainly focus on negating the advantages given by the night to the attacker.

The most obvious effect of is reduced visibility. This affects a soldier's ability to observe friendly troop movements, understand terrain, and especially affects perception of enemy movements and position. Officers find that darkness hampers many aspects of command, including their ability to preserve control, execute movement, firing, maintenance of direction, reconnaissance, security, and mutual support. A U.S. Army report on historic Japanese warfare described an instance of this confusion:

An example is recorded in the history of Japan when about 1180 a force[sic] of the Heike confronting a force of the Genji across the Fuji river (Shizuoka Prefecture) beat a hasty retreat one night due to mistaking the noise made by water fowl for an attacking Genji force.

Indeed, a side effect of the reduced visibility is heightened audibility, as soldiers focus more on what they can hear. There are many instances of soldiers losing their bearings at night due to flashes from guns or enemy searchlights. The difficulties of perception lend themselves to fear of the unknown. Soldiers under fire can't tell where the fire originates and can't devise appropriate countermeasures. Such uncertainty is associated with feelings of loneliness and helplessness, and creates a tendency to over estimate enemy strength or be excessively pessimistic of the combat situation.

And without the aid of artificial illumination, a soldiers marksmanship skills are negatively affected during total darkness. "Prior to the introduction of aided night vision devices, effective firing at night with a rifle was limited to very close distances, typically within 50 meters. The ability to hit targets was dependant upon a soldiers ability to acquire targets in their sights, which in turn, depended greatly upon the amount of natural and artificial illumination."

Night operations have been subject to vast shifts in effectiveness and frequency throughout history, as tactics and technology became more sophisticated.

Night fighting between standing armies was rare in ancient times. Night logistics were mostly limited to the carrying of torches, or navigation by what little light was provided by the stars or moon. However, circumstances occasionally necessitated fighting at night. Usually due to the massive nature of the battles, they could not be resolved in one day, and combat could not be cleanly disengaged as darkness fell, or prevented as armies camped near each other overnight.Sieges which lasted for weeks, months or, even years were often fought day and night. Below are a few notable examples.
