Surrender in military terms is the relinquishment of control over territory, combatants, fortifications, ships, or armament to another power. A surrender may be accomplished peacefully, without fighting; or it may be the result of defeat in battle. A sovereign state may surrender following defeat in a war, usually by signing a peace treaty or capitulation agreement. A battlefield surrender, either by individuals or when ordered by officers, will normally result in those surrendering becoming prisoners of war.
