Mr. Justice DAVIS

delivered tifie opinion of the court.

In the view we take of this case it is unnecessary, to discuss the question — conceding the contract to be lawful— whether the actiob of the naval authorities could -be a ground of claim for damages far a bréac[i of this contract against the *195 United States, because, in.our opinion, the'contract was unauthorized, and had no power to bind the government.

•It appears, .by the findings of the Court of Claims, that Chowan River, in North Carolina, the ’place where the cotton was purchased, was within the lines held by the insurrectionary forces, and that the military safe-conduct protected as well the return as the outward voyage, for Lane was permitted to- take out an outward cargo, under the supervision of a person, styled in the record a sub-agent of the purchasing agent at Norfolk, whose duty it was to retain possession of the cargo until he should have received from Lane on board the vessel, three times its value in cotton.

At the time this contract purports to have been made, this country was engaged in war with a formidable enemy, and by a universally recognized principle of public law, commercial intercourse between states at war with each other, is interdicted.' It needs no special declaration on the part of the sovereign to accomplish this result, for it follows from the very nature of war that trading between the belligerents should cease. If commercial intercourse were allowable, it would oftentimes be used as a color for intercourse of an entirely different character; and in such a case the mischievous consequences that would ensue can be readily foreseen. But the rigidity of this rule can be relaxed by-the sovereign, and the laws of war so far suspended as to permit trade with the enemy. Each state settles for itself its own policy, and determines whether its true interests are better promoted by granting or withholding licenses to trade with the enemy. It being the rule, therefore, that business, intercourse with the enemy is unlawful unless directly sanctioned, the inquiry arises, whether -there was any law of Congress in force at the time that .sanctioned this transaction.

At an early period in the history of the war, Congress legislated on this subject. By an act passed on the 13th of July, 1861,. all commercial intercourse between citizens of States in insurrection and citizens of the rest of the United States was declared unlawful; but liberty was given to the President, in his discretion, to license trade with.the enemy *196 if he thought it would conduce to the public interests to do so. In so far, however, as it was licensed by him, the manner of conducting it was left to be regulated by the Secretary of the Treasury. In the administration of this law, we do not find any regulation prescribed by the Secretary of the Treasury allowing commercial intercourse within the rebel lines. On the contrary, the trade regulations which were issued by him on the 31st of March, 1863, and the 12th of September of the same year, expressly say that commercial intercourse with those parts, of the insurrectionary States within the control of the rebels is absolutely forbidden. Has this policy since then been changed ? It certainly has, if this proceeding was authorized; for-if Risley in his capacity of treasury agent, could lawfully contract with Lane, a citizen of a State not in rebellion, to purchase from him cotton in the country of the public enemy, which he did not own or control, but must procure after he got there, and had the power to assist him in this enterprise, by allowing him to take out a cargo of goods to facilitate the purchase of the cotton, and to furnish for his protection a sub-agent and a "military safe-conduct, then it is clear the door was left open for general trading with the enemy. If one citizen of a State, not in insurrection, could lawfully obtain from a treasury agent the right to transport goods to a place under tfie control of the insurgents, where he could exchange them for cotton or other products of the country, and could also have safe-conduct to take his property there, and to bring out the property he should buy, with the promise on the part of the agent to protect and purchase it,,%o could any other citizen —for in this matter equality niust-be the rule — and in this way it is easy to see a free commercial intercourse with the enemy would'be opened, and a radical change effected in the manner of conducting the war. ■ Was this result contemplated by Congress in the act of July 2d, 1864 ?

It is contended that the 8th section of this act, which says that it shall be lawful for the Secretary of the Treasury, with the approval of the President, to authorize ageuts.to purchase for the United States any products of States declared in in *197 -surrection,-conferred the power to license trading within the military lines of the enemy.

If this were so, and it was the intention of Congress to allow- this trading, providing it was done on government account, why was it not manifested by a specific provision in the law ? Why leave such an important change of policy to be inferred from the general words of the act, and the absence of express words of limitation ?

That the Secretary of the Treasury, who, it is natural to suppose, having the administratioñ of the law in his hands was, before it was passed, consulted about it, did not give this interpi’etation to it, is very clear, for, within a short time after the passage of the act, he adopted, with the approval of the President, a new series of rules regulating commercial intercourse, which were intended to supersede all others, and the third rule absolutely prohibits all intercourse beyond our military lines, and declares further, “ that no permit will be granted for. the transportation of any property to any place under the control of the insurgents.” (See Treasury Regulations,.and Rules for Commercial Intercourse, of July 29th, 1864.)

It is argued, as the regulations which were issued on the 24th of September following, for the express purpose of enforcing that provision of the act reláting to the purchase for the United States of the products of insurrectionary States, do not, in terms, readopt this prohibition against non-intercourse, that therefore it was abandoned. But this does not follow, for there is nothing in these regulations inconsistent with its continuance, and if not expressly revoked, it remained in force. Aside, however, from the construction adopted by the Secretary of the Treasury, we are able to see, by reference to other provisions of the same act, that Congress did not mean to change, by the 8th section, the non-intercourse policy which had prevailed. By the 4th section of this act the prohibitions of the act of July 13th, 1861, were extended even to commercial intercourse -by and 'between persons residing, or being within the lines of National military occupation in districts declared in insurrection, “ with *198 each other;” and the 9th section repeals so much of the act of July, 1861, as made it lawful for the President to license and permit trade by private citizens, in such districts, even within the Federal lines, except to supply the actual wants of the loyal people, aud to authorize persons within the Federal lines to bring to the loyal States the products of their own labor, or of freedmen, &c.

The incorporation of these sections in the law is irreconcilable with the idea that Congress intended, notwithstanding these prohibitions, to confer power on the Secretary of the Treasury to allow citizens of loyal States on government account to trade withizi the actual military lines of the iusuz’gents. If this is not the nature of the power conferred, it is asked what'authority did Congress intend to give the' secretary, and how was it to be exercised ’1 There is 'no difficulty-in answei’iug these questions aud reaching the true meaning of this particular provision, when we consider the entire act, and the treasury regulations adopted to carry into effect the 8th section, in connection with the history of the times/ The law7 was designed to remedy existing evils. The mischiefs atteiiding private trading with the enemy, even, in those parts of the-insurrectionary districts which were for the time withizi our military .lines, had been seriously felt in the conduct of the war, and the best interests of the couutry required that it should cease. It was deemed important, however, to still maizitain some species of commercial intez*coui’se w'ith the insui'gents, for it is well known that the government desired to have, if it did not interfere with military opez’ations, the products of the South, and particularly cotton, brought within our lines. To accomplish this end, and at the same time avoid the complications and embarrassments incidental to private trading, requii’ed the inauguz’ation of a'new-system. This was done by withdrawing from the citizen the privilege of trading with the enemy, and allowing the Secretary of the Treasury, with the approval of the President, -to púnchase through agents, for the United States, any pi’oducts of States declared in insurrection. The inquiry is made, how could these agents pui’chase these products' if *199 privaté citizens were denied the right of trading in the insurrectionary districts, whether they happened tó be within the National or Confederate military lines?/ It would not do to let the army be' used for this purpose, and the only other way left open was to hold out inducements for the.insurgents themselves to bring thejr products to us.

If they could be induced to do this, we would obtain their products which we needed, and in the manner of obtaining them, would avoid the evils inseparable from private trading. The inducements for the insurgents to pursue this course ■were very strong, for besides the liability of having their principal product — cotton—confiscated or destroyed, they were, as is well .known, in want of many of the necessaries of life. They were substantially told in the Regulations of the Treasury Department, “If you will bring your cotton within our lines, we will not only not seize it, but will buy. it from you, and you are at liberty to go to the nearest treasury agent in "an insurrectionary district to sell it, or if you prefer, you can leave it under the control of some one who can go to the agent and sell - it for you.” ■ If this were not enough to accomplish the object, the President of the United States, by way of further inducement^ in an executive order of the same date with the Treasury Regulations, said to them: “You can purchase such articles of merchandise as you need, not contraband of war, to one-third of the aggregate value of the products sold by you, and return with them, and I will guarantee you safe conduct.” Why this limited permission to buy, after the delivery of the products, unless the privilege was for the benefit of thednsurgents ? If private persons, living in the Loyal States, could engage in a venture like this of the claimant, they would need, as he did, to make the venture remunerative, to take with them a cargo of goods to exchange for Southern products; but there was no authority for this. The permission of the President is limited to the taking of a return cargo, bought with part of the proceeds of Southern products, previously sold and delivered to a purchasing agent of the Treasury Department. Indeed, so particular is the direction on this subject, that the *200 military officer commanding at the place of sale, was not authorized to permit a person who had sold Southern products -to buy merchandise,-unless he exhibited to him a certificate of the purchasing agent, setting forth the fact of the purchase and sale, the character and quantity of products, and the aggregate amount paid therefor.

Enough has been said, without pursuing this investigation further, to show there is nothing in the act. itself, the Regulations of the Treasury Department, or the order of the President, to justify Risley in dealing in the manner he did, with Lane. It follows, therefore, that the voyage itself was illegal, as were the contracts and arrangements by which it was undertaken, and that the vessel and cargo were properly seized for being engaged in illegal trading with the enemy.

Although Risley was not authorized in making any contract with a person occupying the status of Lane, still, if he were, he could only do it in the manner and for the purposes pointed out in the Treasury Regulations.

By these regulations the purchasing agent could not act at all until the person desiring to sell Southern products made application, in writing, that he owned or controlled them,, stating their kind, quality, and location, and then the power of- the purchasing agent before the delivery of the products was limited to a stipulation (the form is prescribed) to purchase, and to the giving a certificate that such application was made, and requesting safe conduct for the party and his property.

There is nothing in the petition, or the-findings of the court below, to show that. Lane complied with these provisions. On,the contrary, it is clear from his own statement that he neither owned tor controlled the cotton when he contracted to sell'it, but that,.after the contract was made, he procured it within the rebel lines. . Neither the law, nor the regulations through which it was administered, were intended to protect a speculation of this sort. The purchasing agent had no authority to negotiate even with any one in relation to-the purchase of Southern products, unless at the time of the negotiation he either owned or controlled them. *201 (See Regulations for the purchase of products of insurrectionary States on government account, of September 24th, 1864, and executive order same date.)

The Court of Claims find that no proceedings were taken against the cotton, and that it was restored to the claimant, but that the vessel was libelled at. the instance of the United States, in the Supreme Court of the District of Columbia, where a decree, with costs, passed in favor of the claimant. It is argued, and was so ruled by the court below, that this decree concludes the United States. But the inquiry arises, how far the United States are concluded by it? The record of the admiralty court is not before us, and we only know from the record in this case, that that court refused to render a decree of forfeiture against the vessel, and awarded costs against the United States.

On what ground the court put its decision — whether for want of proof, insufficient allegations, or on the merits of the ease — we have no means of determining.

It may well be that the United States could not re-seize the vessel, or take further proceedings against the cotton, and yet be at perfect liberty to litigate the right of the claimant to damages, in a direct proceeding brought against them to test that question.

There is nothing in this record to show that the Supreme-Court of this District, in decreeing to the claimant the restoration of his vessel, adjudicated on the question of his right to damages. As that court had the power to award damages —and the record is silent on- the subject — it is clear, either that the court refused damages, or that the claimant did not insist on the court considering the question.

The United States are, therefore, not concluded on this point, and the case is relieved of all difficulty.

The judgment of the Court of Claims is reversed, and this cause is remanded to that court, with directions to enter

An order, dismissing the petition.
