siege

n. blockade, act of surrounding and attacking a fortification in order to cut off supply and aid routes; prolonged period of difficulty or trouble

v. blockade, besiege, surround and attack a fortification in order to cut off supply and aid routes

A siege is a military blockade of a city or fortress with the intent of conquering by force or attrition, often accompanied by an assault. The term derives from the Latin word for "seat" or "sitting." A siege occurs when an attacker encounters a city or fortress that refuses to surrender and cannot be easily taken by a frontal assault. Sieges involve surrounding the target and blocking the reinforcement or escape of troops or provision of supplies (a tactic known as "investment"), typically coupled with attempts to reduce the fortifications by means of siege engines, artillery bombardment, sapping (also known as mining), or the use of deception or treachery to bypass defenses. Failing a military outcome, sieges can often be decided by starvation, thirst or disease, which can afflict both the attacker or defender.
