The commander of the army must leave it to the ultimate treaty of peace to settle the permanency of this change.

It is no longer considered lawful—on the contrary, it is held to be a serious breach of the law of war—to force the subjects of the enemy into the service of the victorious government, except the latter should proclaim, after a fair and complete conquest of the hostile country or district, that it is resolved to keep the country, district, or place permanently as its own and make it a portion of its own country.
34
As a general rule, the property belonging to churches, to hospitals, or other establishments of an exclusively charitable character, to establishments of education, or foundations for the promotion of knowledge, whether public schools, universities, academies of learning or observatories, museums of the fine arts, or of a scientific character—such property is not to be considered public property in the sense of paragraph 31; but it may be taxed or used when the public service may require it.
35
Classical works of art, libraries, scientific collections, or precious instruments, such as astronomical telescopes, as well as hospitals, must be secured against all avoidable injury, even when they are contained in fortified places whilst besieged or bombarded.
36
If such works of art, libraries, collections, or instruments belonging to a hostile nation or government, can be removed without injury, the ruler of the conquering state or nation may order them to be seized and removed for the benefit of the said nation. The ultimate ownership is to be settled by the ensuing treaty of peace.
In no case shall they be sold or given away, if captured by the armies of the United States, nor shall they ever be privately appropriated, or wantonly destroyed or injured.
