The first quote is of Henry V's supposed reaction at the Battle of Agincourt 1415 to the murder of his army's boy servants. The second is that of his Welsh captain, Fluellen, who clearly had a better understanding of the Law of Arms (later the Laws of War). This chapter is headed ‘The law of armed conflict’ since that is the more correct term to describe the international law governing the conduct of hostilities, including military occupation. International lawyers also use the Latin term jus in bello to distinguish it from jus ad bellum, the law on the use of force. But the currently fashionable term used by the United Nations, the International Court of Justice and the International Committee of the Red Cross is ‘international humanitarian law’ (IHL). This reflects the law's fundamentally humanitarian purpose, but can mislead people into thinking that the subject covers all human rights, or even that it is concerned with humanitarian aid.
