Execution by firing squad, sometimes called fusillading (from the French fusil, rifle), is a method of capital punishment, particularly common in the military and in times of war. Execution by shooting is a fairly old practice. Some reasons for its use are that firearms are usually readily available and a gunshot to a vital organ usually kills the subject relatively quickly. Before the introduction of firearms, bows or crossbows were often used — Saint Sebastian is usually depicted as executed by a squad of Roman auxiliary archers in around 288 AD; King Edmund the Martyr of East Anglia, by some accounts, was tied to a tree and shot dead by Viking archers on 20 November 869 or 870 AD.
