Mr. Justice Wayne
delivered the opinion of the Court.
This case arises upon the mandate of this Court on the case of Colin Mitchel and others v. The United States, reported in 9 Peters, 711.
In that case, it will be seen, that the lands claimed by the plaintiffs were in different tracts, and that this Court, in confirming the title of the plaintiffs, excepted from one of them the fortress of St. Marks, and " the territory directly and immediately adjacent and appurtenant thereto," which were reserved for the United States. The Court further decreed, that the territory thus described, shall be that which was ceded by the Indian proprietors to the crown of Spain, for the purpose of erecting the said fort:, provided the boundaries of said cession can be ascertained. If the boundaries of the' said cession cannot now be ascertained, then the adjacent lands, which were considered and held by the Spanish government, or the commandant of the post, as annexed to the fortress, for military purposes, shall be still considered as annexed and reserved with it, for the use of the United States. If no evidence can be obtained to designate the extent of the adjacent lands, which were considered as annexed to St. Marks, as aforesaid, then so much land shall be comprehended in this exception, as, according to military usage, was attached generally to forts in Florida, or the adjacent colonies. If no such military usage can be proved, then it is ordered and decreed, that a line shall be extended from the point of junction between the rivers St. Marks and Wakulla, to the middle of the river St. Marks, below the junction, thence extending up the middle of each river, three miles in a direct line, without computing the courses thereof; and that the territory comprehended within a direct line, to be run so as to connect the points of termination on each river, at the end of the said three miles up each river- and the two lines to be run as aforesaid, shall be, and the same are hereby declared to be the territory reserved, "as adjacent and appurtenant to the fortress of St. Marks;" and as'such reserved for the use of the United "States. To which, the claim of the petitioner is rejected; and as to which, this Court decree, that " the same is a part of the public lands óf the United States."
The Court then reverses the decree of the Court below, declaring it to be reversed and annulled in all matters therein contained, With the'exception-aforesaid; and proceeding to render such decree as the Court below ought to have rendered, decreed the claim of the petitioners valid, to all the land claimed, except to such part as it had excepted. The clerk of this Court is directed to certify its decree to the Surveyor General of Florida, with 'directions to' survey and lay off the lands described in the petition of the claimant, according to the lines, boundaries, and description thereof in the several deeds of cession, grant, and confirmation by the Indians or Governor of West Florida, filed as exhibits in the cause, or referred to in the record théreof; excepting, nevertheless, such part of the traet granted in 1811, lying east of the tract granted in 1804 and 1806, as is hereby declared to be the territory of the United States, pursuant to the exception hereinbefore mentioned, and to make return thereof, according to law, as to all the lands comprehended in the three first herein mentioned tracts; and as to the tract last mentioned, to survey, and in like manner to .lay óff the same, ns soon as the extent of the land excepted and reserved for the use of the United States shall be ascertained in the manner directed. And the Court directs that the land excepted and reserved, shall be ascertained and determined by the Superior Court of the middle district of Florida, in such manner and by such process as is prescribed by the acts of Congress, relating to the claims of.lands in Florida; the Court rendering thereupon such judgment or decree as to law shall appertain.
This mandate was filed by the plaintiffs in the Superior Court of Middle Florida. They afterwards filed a bill, claiming from the Court a confirmation of their title to the land excepted, up to the walls of the fort of St. Marks; assert this claim, upon the ground of the laws, usages, and military practice, in the various, colonies of Spain;'and then, in an amended bill, they ask the Court to decree to them, the fee in the land covered by the fort, as well as that adjoining and appurtenant, because they say the land on which the fort is erected was originally obtained from the Indians, for the purpose of erecting a fortification, to be occupied and used as such, for that express purpose and no other.' The attorney of the United States filed exceptions and an answer to the bills of the plaintiffs, alleging, among other things, that all the points in dispute between the United States and the plaintiffs, concerning the land they claimed, had been settled by the decision and'mandate in the original case; and that the only object of this Court, in referring the mandate to the Court below, was, that it mjght ascertain the extent and boundaries of the tract of land which includes the fortress of St. Marks, and the territory adjacent; to which the claim of the petitioner had been rejected, and which had been reserved for the use of the United States. .
On these pleadings, and the evidence taken in it, the cause was tried. The Court expresses the opinion, that the boundaries of the territory ceded by the Indians to Spain, for the purpose of erecting the fortress of St. Marks, cannot now be ascertained; that no evidence can now be obtained to designate the extent of the adjacent lands which were considered as annexed to the fort, by the crown of Spain, or the commandant of the post; but declares there is sufficient evidence of the military usage of Spain, to determine the extent of land adjacent to forts in Florida;, which were usually attached to said forts. The Court proceeds to say the extent of such reservations was determined by a radius of fifteen hundred .Castilian varas, from the salient angles of the covered way all round the works; or, there being no covered way, from the salient angles of the exterior line of the ditch. A decree is made by the Court, conformably with Jhis opinion, from which the plaintiffs appeal.
It is urged for the appellants, that as the sale from the Indians to Forbes and Company calls for the St. Marks river as the eastern boundary of the cession and grant; and as the title to the land was in the Indiáns, with only-a pre-emptive right 'to the ultimate fee in the soil in the King of Spain, with the additional right of assenting to, or rejecting sales, by the Indians; that if no formal cession, or transfer of the land, upon which the fort is erected, can be found from the Indians to Spain, before the sale to Forbes and Company, confirmed, as it was, by the authorities of Spain, without any exception of the .site of the fort' or land appurtenant to it, that the adjacent land up to the walls'of the fort belongs to the claiaiants, and the site of the fort also, in the event of its abandonment as a fortification; that the right to the site would have been consummated in the claimants, in virtue of the sale by the Indians, .if it had been disused as a fortress by Spain before Florida was ceded to the United'States; and that , the latter could only hold it for the same use, oras Spain held it; and, now having been discontinued by the United States as a fortress, that the. claimants were entitled to it in fee. It was also said, that the Spanish government recognised by its laws the ownership of lands to the walls of forts; and that military usage, in Florida, and the adjacent colonies, permitted it.
' The case before us does not require any discussion upon the nature and extent of the property held by the Florida Indians in these lands under Spain-. .That was satisfactorily done in the decision given by this Court in the original case, 9 Peters. It was then shown, that the Indians " held under Great Britain and Spain, a right of property in these lands, which could not be impaired,without a violation of the laws of both, and the sanctity of repeated'treaties." 9 Peters, 756. " That Spain did not consider the Indian right to be that of mere occupancy and perpetual possession, but a right of property in the lands they held under the. guaranty of treaties; Which were so highly respected, that in the establishment of a military post by a royal order, the site thereof was either purchased from the Indians, or occupied with their permission, as that of St. Marks." 9 Peters, 752.
These extracts present the claim of the appellants under their Indian title, and confirmation of it by Spain, in its strongest light. The last of them is particularly applicable to the point in controversy.
It is then to be determined whether the Court below, in its judgment, has rightly apprehended and executed the mandate of this Court. -
The meaning of the mandate maybe ascertained from the instrument. itself; but'the reasons which induced the Court to make it, are to be found in the evidence contained in the original re'cord. The Court will now do what it did in the case of Sibbald, 12 Peters, 493. It said, "To ascertain the true intention of the decree and mandate of this Court, the decree of the Court below, and of this Court, and the petitioners' title, must be taken into consideration." In 10 Wheat. 431, this Court says, " The proceedings in the original suit are always before the Court, so far as to determine any new points between the parties."
Prom the evidence then adduced by the claimants in the original .case, it appeared that when the Floridas were retroceded to Spain, by England, September, 1793, that Panton, an'English merchant, resided at St. Augustine, and traded with the Indians in East Florida. Rec. 114. In 1784, Governor Mero, finding it necessary to cultivate trade with the Indians, gave permission to one Mather to bring two vessels from London, direct to Pensacola and Mobile, laden with goods of British manufacture, to supply the Indians. In July, 1784, Panton applied to Governor Zespedes for leave to remain in the province, with permission to' import from Great Britain such articles as the Indian trade required, and to export peltries received in payment. Rec. 157. A royal order was passed on the 8th May, 1786, (Rec. 160,)^ allowing Panton and his partners to remain in Florida, on their taking the oath of alliegance, and permitting them to trade with the Indians. They were allowed to send a ship, annually, to Pensacola, with British goods, and to take back peltries. Rec. 118. In 1787 or 1788, (Rec. 162. 304,) they were allowed to erect a storehouse on the. river St. Marks, to collect their peltries; and the vessel from Pensacola was permitted to go there to load them. In 178.9, Panton was intrusted with the exclusive trade, (Rec: 118. 250;) and in 1791, received a special royal license.. The year after, an attack was made by the Indians, under' Bowles, on Panton's store, on the river St. Marks, and much property taken away. The same kind, of outrage was repeated in 1800, with heavy loss to Panton and his associates. The Indians also owed them a large sum for goods. Forbes succeeded Panton in the trade which the latter began with the Indians, and was the assignee of his claimsupon the -Indians. In January, 1801,. (Rec; 56,) he informs the Marquis Casa Calvo, that he had been negotiating with the Indians to cede lands in payment of the debt, and. in satisfaction for the outrages committed by them on the store at St. Marks. -The Governor countenanced the negotiatibn. In 180.4, Inverarity, an agent of Forbes, informed Governor Folch that the Indians had agreed to sell the land, and asks his consent to complete the purchase. The consent w.as given. On the 25th May, a deed was made, and in August, in a full. Indian council,'held at . St: Marks, the Governor being present, the sale was ratified. This was Forbes's first purchase. If embraced the land between the Appalachicola and Wakulla, extending several miles up the rivers. The boundaries of this first purchase we're run and fixed by the Indians, in 1806, All the surveys being completed irithin that year, Governor Folch confirmed'the- grant, and gave the grantees possession. Rec. 618. 622. 74: In January, 1811, -a. new negotiation was made with the Indians, ánd they agreed to sell additional strips of land on the western, northern, and eastern sides of the first purchase; but the cession was of " all the right the Indians had retained in the land until that time." ' The eastern addition embraced the land from the Wakulla to the Sti Marks, and down the latter to the sea; thus including the-point between the two rivers. This second cession was also confirmed by Governor Folch, in June, 1811. Thus matters stood, the cession. being known as Forbes's land; and the fort of St. Marks continuing to be garrisoned by Spain until it was surrendered to the' United' States, under the i treaty. The history of the grants to the claimants .having been traced, it is here necessary to give that, of the fortress of St. Marks, as it is to be collected from the evidence in the original case.
In the record, 123, a'despatch from the Marquis of Casa Calvo shows that during the possession of Florida .by the English, thé fort of St. Marks had been a military post; though it had been abandoned, and suffered to go to decay. Shortly after its retrocession fo Spain, the latter extended the jurisdiction of West Florida,-so as to include the site of the fort. Rec. 189. In May, 1785, Count Galvas issued an order to repair the old fort at St. Marks, and a detachment of troops was ordered to it from Pensacola.. - Rec: 306. This detachment was cut off, or driven away by,the Indians. Rec. 582. But in the spring of 1787, (Rec. 198. 3Ó6,) a royal order was issued, directing the permanent establishment .of the fort. " It is notorious and public," (Rec. 233,) says Governor Folch, the principal witness of the claimants, and the person who gave them possession of their whole purchase, "that at the establishment of the fort of St. Marks, at Appalachia in the year 1787, all the solemnity and requisites were observed to obtain from the Indians in sale, the lands necessary to that object." Benigno de Calderon, who was then an officer of the Spanish government, twice refers to the " fact, that not merely a military post itself, " but the quantity of land needed to preserve it;" and what he calls "the circle of jurisdiction of a fortified ffiace;" was severed from the Indian land, and vested in the government of Spain. Rec. 570. 582.
Immediately after the sale of which Governor Folch speaks, the fort was constructed by Spain, at a heavy expense. So were the public stores. The evidence of the claimants'shows at least two hundred thousand dollars were expended upon these works. Calderon says there was. a regular Spanish garrison^ there from 1787 to 1818. Caro says the.. Governor exercised both civil and military jurisdiction. When Florida was ceded to the United States, St. Marks was given up as a military fortress of the King of Spain. Such is the history of the fortress of St. Marks, taken from the testimony and the witnesses of the claimants in the original case. Is it surprising then, that the Court in its mandate should have excepted the fort and land directly adjacent to it from its confirmation of the claimant's title to the lands bought by them from the Indians? The king's royal order to establish afort at St. Marks, the occupancy of the fortress for more than twenty years before any grant was made to Forbes, tyenty-five years before the grant was made, which includes it, and forty years occupation of it with the use of the land adjacent; seemed to the Court to be inconsistent with the idea that ii was intended to be included in the sale, by the Indians, or by the confirmation of that sale by Governor Folch. It must be remembered, also, that when Governor Folch gave possession of the land to the grantees, that the fort was retained, and that the land, to the extent at least of what is termed the circle of military jurisdiction had been cleared, and that the grantees, though living by permission for protection of .themselves and their trade, within that circle, never exercised by cultivation ór otherwise any acts of ownership over any part of it. Besides, the. Court was advised, when the decision in the original case, was. made, that by the laws of the Indies, reservations of lands were made appurtenant to fort's, though the extent of such reservations was not known. It was then, however, a subject of inquiry, and would-no doubt have been fully investigated; if the counsel for the claimant had not admitted in his argument, that .the Indian title for. the sale of the fort of St. Marks, had been' extinguished by a negotiation made by the Governor of' West Florida. In the opinion' of the Court, given by Mr. Justicé Baldwin, is found."the following paragraph: " Iris objected that the grant of 1811 is invalid, because it comprehends the fort of St. Marks, then actually occupied by the troops of the king. It is in full proof that the site of St. Marks and the adjacent country was within the territory claimed by the Seminole Indians. Ree. 12. 131. 603 — 607. 618.. It is not certain, from the evidence, whether it was phrchased from the Indians, or merely occupied by their permission; there seems to be no written evh dence of the purchase, hut.no witnéss asserts that possession was taken adversely to the Indian claim, and it is clearly proved to have been amicably doné. Rec. 282. 306. 581. Whether the Indians had a right to grant this particular spot then or not, cannot affect the validity of the deeds to the residue of the lands conveyed in 1811. The grant is good so far as it interfered with no prior right of the crown, according to the principles settled by this Court, in numerous cases, arising on grants by North Carolina and Georgia, extending partly over the Indian boundary, which have uniformly been held good, as to whatever land was within the line established • between the state and the Indian territory. Wear v. Danforth, 9 Wheat. 673. Patterson v. Jenckes, 2 Pet. 216; and Winn and Patterson, decided by the Supreme Court of the United States. • As to the land covered by the fort and appurtenances, to some distance around it, it became unnecessary to inquire into the effect of the deeds, as the counsel of the petitioners have in open Court disclaimed any pretensions to it." It is not, however, upon this disclaimer of the claimants' counsel, that the Court relies to sustain the judgment of the Court below upon the mandate. It is cited only to them to show that the subjéct .matter of the present'controversy was'considered by the Court. That the Court, not knowing at that time what should be the reservation appurtenant to the fort of St. Marks, directed it to be ascertained, and excepted it absolutely .from the grant of the claimants'; declaring it to be a part of the public lands of the United States. The object of the Court, was to put these claimants in respect to the lands which they claimed, in the condition they would have been, if Florida had not been ceded to the United States. It was the intention of the Court, in the language of. the treaty, to put them in possession of the lands, to the same extent that the same grants would be valid, if the territories had remained under the dominion of his Catholic Majesty. Can it be supposed for a moment, when the king, by his royal order, -directed the Intendant General of Cuba-, to inquire into the subject of the indemnity, which should be made to the house of Panton, Leslie, and Company, for services to the crown and for Indian depredations, that he would have sanctioned, or that the Intendant General would have ventured to propose a cession of land, including public stores and a fortress, which had been built at a great expense, at an important point on the coast, which was essential to control and kéep the Indians in subjection, and all-important to resist external attack.-
Does any one believe, when Governor Folch sanctioned the purchases, confirmed and gave possession of the lands to Forbes- and Company, that he would have done either, if he had thought he was giving to them a title to the fort of St. Marks, and its circle of military jurisdiction, against the king; or that the Captain General of Cuba, to whom Governor Folch reported his proceedings in this matter, would have approved and declared that the king would confirm them; if he had supposed that he was permitting the Indians to sell a; fortress, then garrisoned by the troops of Spain* and'which had been so for more than twenty years ? Is it not certain nothing of the kind was intended, when it is remembered that Governor Folch, who superintended the sale of the land, marked out its boundaries, and gave possession of it to the original grantees, says: " It is notorious and public, that.at the establishment of the fort of St. Marks; at Appalachia, in. the year 1787, all the solemnities and requisites were observed, to obtain from the Indians in sale, the lands necessary to that object?"
We will not enter into the question,'how far the appropriation of the land for a fortress,' by order of the government, extinguished the Indian title. It might be done successfully, upon the positions takén by this Court in respect to'the rights of European •monarchs to Indian -lands in North America, in Johnson and M'Intosh, 8 Wheat. We are inclined to put this case upon fapts disclosed by the claimants',, evidence in the former cause, and the inferences and arguments which may be drawn from them, because the Court did not do so, in its decision, in consequence of the admission of counsel, "that the land covered by the fort and appurtenances, to some distance around it," were not contended for.
In addition to what has been said, however, in respect to St, Marks, and the appurtenant land, not being within the grant from the Indian? to the claimants, we remark, that the subject may he satisfactorily disposed of, by a reference to the second article of the treaty with Spain. " His Catholic Majesty cedes to the United States, in full property and sovereignty, all the ter ritories which belong to him, situated to the eastward of the Mississippi, known by the name of East and West Florida; the adjacent islands dependent on said provinces; all public lots, and squares, vacant lands, public edifices, fortifications, barracks, and other buildings, which are not private property." In the construction of this article, it will be admitted, that the last mémber of the sentence cannot refer to any of the enumerated cessions, notorious as public property, or that it must be confined to the terms, " other buildings in connexion with it." The treaty then secures to the United States the fort of St. Marks, and so much land appurtenant to it as, according to military usage, was attached generally to forts in Florida, or the adjacent colonies. Was there any such psage, and has it been established by sufficient testimony to sustain the judgment of the Court below? We think there was, and that the proofs are sufficient. At the instance of the claimants, the testimony of the director of enginee rs was taken by order of the Governor General Tacón. His evidence on the record before us, is that, "a radius of 1,500 Castilian varas, is measured from the salient angles of th'e covered way, all around the fortification." That such was the rule, is confirmed by a document introduced by the claimants, 'as evidence in this case. In 1801 a petition was presented-to Governor White, for a grant of. land at Macariz. He referred it to the chief engineer. The engineer reported it to be within one thousand five hundred yards of the castle, i! that it cannot be cultivated in corn, nor can ditches, or thorn fences, be allowed; that plants of a low growth, and vegetables may be permitted to be cultivated, and it may be allowed for the security of the produce to erect simple post and rail fences, which may be sufficient to prevent animals from breaking in." Under these restrictions, it was granted;.so that it could only be used in such a way, as could not interfere with the defensive and offensive power of the castle. Several witnesses were, examined on this point: all of them concur in saying a fortress cannot be defended, unless it has the command of the ground around it, to a considerable extent. Colonel Murat gives asifieusage of the European armies, tha.t from the salient angles ot the covered way, a radius of three thousand, four hundred yards.- is marked, in which it is not permitted to' erect any permanent buildings, or embankment, or stone fences, of ditches. We know it, also, to be the usage of all civilized nations, to assert such rights over thé ground adjacent to fortifications, in a time of war. It is reasonable, then, to conclude, that European monarchs, in the construction of permanent fortifications, in the new world, upon Indian lands before it had been granted by the sovereign, or permitted to be alienated by the . Indian, intended to appropriate so much of the land adjacent to a fortification as was necessary to defend it. That it was so intended in the instance of St. Marks, is strpngly corroborated by the testimony of Col. Butler, who says the woods had been cleared away by the authorities at St. Marks, to the distance of a mile and a half ^from the Walls. Another fitness says, no buildings were erected outside of the fort, before 1827, and then, by permission of the United States. It is hard to resist the conclusion, that such a clearing before the sale by the Indians, without the cultivation or occupancy of any part of it, by the grantees, from the time of the Indian sale, to the surrender of the fort to the United States, does not indicate an intention upon the. part of the authorities of Spain, to reserve some land adjacent to the fort for military purposes; and the acquiescence of the purchasers, that though withiiti the boundaries of the grant,, the fort and land attached to it by military usage was not intended to be conveyed. Nor can we admit, as.it was argued by the counsel of the appellants, that the instances cited in the record of grants of land, up to the walls of fortifications, by the Spanish authorities in Florida and Louisiana, disprove the existence of .a military usage to reserve land adjacent to forts in them. Those instances are exceptions out of the military laws of Spain, as contained in the royal ordinances; which declare that " a radius of one thousand, five hundred varas is measured from the salient angles of the covered way." We do not think it necessary to remark further upon the opinion given by the chief engineer, in réspect to the manner in which such titles were acquired to land adjacent to fortifications, or the extent of the military jurisdiction over them, than to observe the fact of certain reservation being declared by him, as a fact; we require something more than his conclusion or inference, that there was no reservation according to the military usage and ordiilances of Spain, in the instance of St. Marks. Our opinion is, that the Court below has fully apprehended and executed the judgment of this Court; and its judgment is accordingly affirmed.- .
This case carné on to be heard,, on the transcript of. the record from the Superior Court of the middle district of Florida, and was argued by counsel. On consideration whereof, it is ordered and decreed by this Court, that the decree of the said Superior Court in this cause be, and the same is hereby, affirmed'.
