Morrison Waite,
Haycraft v. United States — Opinion of the Court
“ From time to time in the progress of the war it was found upon the enemy's territory occupied by the military forces of the United States. While, when so found, it might have been owned by non-combatant enemies and, in that sense, private property, it was in fact, under the circumstances, at least semi-public. If left undisturbed, and the insurgents should repossess themselves of the territory, it would again be placed where it might strengthen the rebellion. Its capture was, therefore, legitimate; not for booty, but to cripple the enemy. In that way it was kept out of the insurgent treasury. ”
