Not only did foreign powers recognize their right to make war, not as rebels but as legitimate belligerents entitled to all the consideration that the laws of civilized war guarantee to nations, but the United States government itself made similar recognition of the South's status as a power possessed of the right to make war. At the outset there was quibbling of course, and a deal of playing for position. But in view of the obvious facts all this quickly gave way to a perfectly frank recognition on both sides of the truth that there was legitimate public war between the North in the name of the Union and the South organized as the Southern Confederacy; that the struggle involved the question of the independence of the South on the one hand and the indissolubility of the Federal Union on the other; that the conflict was the result of an entirely legitimate appeal to arms for the decision of questions which no other arbitrament could decide; and that the contest must be fought out not as a struggle between constituted authority on the one hand and insurrection on the other but as a controversy between two powers, each of which was legitimately entitled to assert its contentions and to maintain its attitude by every means known to civilized war. All this was reflected, while the war lasted, in the treatment of men captured on either side as prisoners of war; in negotiations for the exchange of prisoners with full recognition of military rank on either side; in the issue, the observance and the enforcement of paroles; in safe conducts frequently granted and always honorably respected; in agreements for the immunity from arrest of medical officers and other non-combatants; in the humane and civilized arrangements made between opposing generals for the equal care of the wounded of either army by the surgeons of both, and in a score or a hundred other ways.
