Contraband of War

Are such articles as a belligerent has by the law of nations the right of preventing a neutral from furnishing to his enemy. Articles contraband of war are, in general, arms and munitions of war and those out of which munitions of war are made. Contraband articles are subject to confiscation; but very arbitrary interpretations have been affixed to the term by powerful states, when able to enforce them by arms. Thus, provisions are held contraband of war when it is the object to reduce the enemy by famine. But with respect to these and other articles not in their nature contraband, it seems to be the practice that the belligerent should purchase them from the neutral for a reasonable equivalent, instead of confiscating.
