The right of belligerent states to make use of (or destroy if necessary) neutral property on their own or on enemy territory or on the open sea, for the purpose of offence and defence. Traditionally, the right (jus angariae) was restricted to the belligerent laying an embargo on and seizing neutral merchant ships in its harbours and compelling them and their crews to transport troops, ammunition, and provisions to certain places on payment of freight in advance. However, all sorts of neutral property, including vessels or other means of transport, arms, ammunition, provisions, or other personal property, may be the object of the modern right of angary, provided the articles concerned are serviceable to military ends and wants. It has been contended that one ground for distinction between angary and other forms of expropriation (i.e. requisition) is the quantum of compensation. In cases of angary full compensation is payable, whereas in other cases of expropriation less than full compensation may suffice.
