  Usage: Battle, Combat, Fight, Engagement. These words agree in denoting a close encounter between contending parties. Fight is a word of less dignity than the others. Except in poetry, it is more naturally applied to the encounter of a few individuals, and more commonly an accidental one; as, a street fight. A combat is a close encounter, whether between few or many, and is usually premeditated. A battle is commonly more general and prolonged. An engagement supposes large numbers on each side, engaged or intermingled in the conflict.
