Campagne militaire

A military campaign is large-scale long-duration significant military strategy plan incorporating a series of interrelated military operations or battles forming a distinct part of a larger conflict often called a war. The term derives from the plain of Campania, a place of annual wartime operations by the armies of the Roman Republic.

1. A military campaign denotes the time during which a given military force conducts combat operations in a given area (often referred to as AO, area of operation). A military campaign may be executed by either a single Armed Service, or as a combined services campaign conducted by land, naval, air, cyber and space forces.
2. The purpose of a military campaign is to achieve a particular desired resolution of a military conflict as its strategic goal. This is constrained by resources, geography and/or season. A campaign is measured relative to the technology used by the belligerents to achieve goals, and while in the pre-industrial Europe was understood to be that between the planting (late spring) and harvest times (late autumn), it has been shortened during the post-industrial period to a few weeks. However, due to the nature of campaign goals, usually campaigns last several months, or up to a year as defined by Trevor N. Dupuy. "A campaign is a phase of a war involving a series of operations related in time and space and aimed towards a single, specific, strategic objective or result in the war. A campaign may include a single battle, but more often it comprises a number of battles over a protracted period of time or a considerable distance, but within a single theatre of operations or delimited area. A campaign may last only a few weeks, but usually lasts several months or even a year". Planning – the General Staff defining objectives, time, scope and cost of the campaign Executing – the coordination of forces and resources in logistic and combat operations Controlling – the monitoring of the progress of the campaign when compared to its baseline plan Concluding – acceptance or rejection of the campaign outcomes by the directing command structure In premodern times, campaigns were usually interrupted during the winter season, during which the soldiers retreated into the winter quarters (or 'cantonments') to get through the coldest months with warmth and protection.
