In anticipation of war the British Admiralty took the military measure of consolidating their transatlantic stations, with the exception of Newfoundland. The Jamaica, Leeward Islands, and Halifax squadrons, while retaining their present local organizations, were subordinated to a single chief; for which position was designated Admiral Sir John Borlase Warren, an officer of good fighting record, but from his previous career esteemed less a seaman than a gallant man. This was apparently his first extensive command, although he was now approaching sixty; but it was foreseen that the British minister might have left Washington in consequence of a rupture of relations, and that there might thus devolve upon the naval commander-in-chief certain diplomatic overtures, which the Government had determined to make before definitely accepting war as an irreversible issue. Warren, a man of courtly manners, had some slight diplomatic antecedents, having represented Great Britain at St. Petersburg on one occasion. There were also other negotiations anticipated, dependent upon political conditions within the Union; where bitter oppositions of opinion, sectional in character, were known to exist concerning the course of the Administration in resorting to hostilities. Warren was instructed on these several points.

It was not until July 25, 1812, that a despatch vessel from Halifax brought word to England of the attack upon the "Belvidera" by Rodgers' squadron on June 24. By the same mail Admiral Sawyer wrote that he had sent a flag of truce to New York to ask an explanation, and besides had directed all his cruisers to assemble at Halifax.[491] The Government recognized the gravity of the news, but expressed the opinion that there was no evidence that war had been decided upon, and that the action of the American commodore had been in conformity with previous orders not to permit foreign cruisers within the waters of the United States. Some color was lent to this view by the circumstance that the "Belvidera" was reported to have been off Sandy Hook, though not in sight of land.[492] In short, the British Cabinet officially assumed that facts were as they wished them to continue; the course best adapted to insure the maintenance of peace, if perchance not yet broken.

On July 29, however, definite information was received that the United States Government had declared that war existed between the two countries. On the 31st the Cabinet took its first measures in consequence.[493] One order was issued forbidding British merchant vessels to sail without convoy for any part of North America or the West Indies; while another laid an embargo on all American merchant ships in British ports, and directed the capture of any met at sea, unless sailing under British licenses, as many then did to Continental ports. No other hostile steps, such as general reprisals or commercial blockade, were at this time authorized; it was decided to await the effect in the United States of the repeal of the obnoxious Orders in Council. This having taken place only on June 23, intelligence of its reception and results could not well reach England before the middle of September. When Parliament was prorogued on July 30, the speech from the throne expressed a willingness still "to hope that the accustomed relations of peace and amity between the two countries may yet be restored."

It is a coincidence, accidental, yet noteworthy for its significance, that the date of the first hostile action against the United States, July 31, was also that of the official promulgation of treaties of peace between Great Britain, Russia, and Sweden.[494] Accompanied as these were with clauses embodying what was virtually a defensive alliance of the three Powers against Napoleon, they marked that turn of the tide in European affairs which overthrew one of the most important factors in the political and military anticipations of the United States Administration. "Can it be doubted," wrote Madison on September 6, "that if, under the pressure added by our war to that previously felt by Great Britain, her Government declines an accommodation, it will be owing to calculations drawn from our internal divisions?"[495] Of the approaching change, however, no sign yet appeared. The reverses of the French were still in the far future. Not until September 14 did they enter Moscow, and news of this event was received in the United States only at the end of November. A contemporary weekly, under date of December 5, remarked: "Peace before this time has been dictated by Bonaparte, as ought to have been calculated upon by the dealers (sic) at St. Petersburg, before they, influenced by the British, prevailed upon Alexander to embark in the War.... All Europe, the British Islands excepted, will soon be at the feet of Bonaparte."[496] This expectation, generally shared during the summer of 1812, is an element in the American situation not to be overlooked. As late as December 4, Henry Clay, addressing the House of Representatives, of which he then was Speaker, said: "The British trade shut out from the Baltic—excluded from the Continent of Europe—possibly expelled the Black Sea—perishing in South America; its illicit avenue to the United States, through Canada, closed—was this the period for throwing open our own market by abandoning our restrictive system? Perhaps at this moment the fate of the north of Europe is decided, and the French Emperor may be dictating the law from Moscow."[497] The following night Napoleon finally abandoned his routed army and started on his return to Paris.

War having been foreseen, the British Government took its first step without hesitation. On August 6 the Foreign Office issued Warren's secret instructions, which were substantially the repetition of those already addressed on July 8 to its representative in Washington. It being probable that before they could be received he would have departed in consequence of the rupture, Warren was to submit the proposition contained in them, that the United States Government, in view of the revocation of the Orders in Council, so long demanded by it, should recall the hostile measures taken. In case of acceptance, he was authorized to stop at once all hostilities within his command, and to give assurance of similar action by his Government in every part of the world. If this advance proved fruitless, as it did, no orders instituting a state of war were needed, for it already existed; but for that contingency Warren received further instructions as to the course he was to pursue, in case "a desire should manifest itself in any considerable portion of the American Union, more especially in those States bordering upon his Majesty's North American dominions, to return to their relations of peace and amity with this country." The admiral was to encourage such dispositions, and should they take shape in formal act, making overtures to him for a cessation of hostilities for that part of the country, he was directed to grant it, and to enter into negotiations for commercial intercourse between the section thus acting and the British dominions. In short, if the General Government proved irreconcilable, Great Britain was to profit by any sentiment of disunion found to exist.[498]

Warren sailed from Portsmouth August 14, arriving in Halifax September 26. On the 30th, he despatched to the United States Government the proposal for the cessation of hostilities. Monroe, the Secretary of State, replied on October 27. The President, he said, was at all times anxious to restore peace, and at the very moment of declaring war had instructed the chargé in London to make propositions to that effect to the British Ministry. An indispensable condition, however, was the abandonment of the practice of impressment from American vessels. The President recognized the embarrassment under which Great Britain lay, because of her felt necessity to control the services of her native seamen, and was willing to undertake that hereafter they should be wholly excluded from the naval and merchant ships of the United States. This should be done under regulations to be negotiated between the two countries, in order to obviate the injury alleged by Great Britain; but, meanwhile, impressing from under the American flag must be discontinued during any armistice arranged. "It cannot be presumed, while the parties are engaged in a negotiation to adjust amicably this important difference, that the United States would admit the right, or acquiesce in the practice of the opposite party, or that Great Britain would be unwilling to restrain her cruisers from a practice which would have the strongest tendency to defeat the negotiation." The Orders in Council having been revoked, impressment remained the only outstanding question upon which the United States was absolute in its demand. That conceded, upon the terms indicated, all other differences might be referred to negotiation. Upon this point Warren had no powers, for his Government was determined not to yield. The maritime war therefore went on unabated; but it may be mentioned here that the President's undertaking to exclude British-born seamen from American ships took effect in an Act of Congress, approved by him March 3, 1813. He had thenceforth in hand a pledge which he considered a full guarantee against whatever Great Britain feared to lose by ceasing to take seamen from under the American flag. It was not so regarded in England, and no formal agreement on this interesting subject was ever reached.

The conditions existing upon his arrival, and the occurrences of the past three months, as then first fully known to Warren, deeply impressed him with the largeness of his task in protecting the commerce of Great Britain. He found himself at once in the midst of its most evident perils, which in the beginning were concentrated about Halifax, owing to special circumstances. Although long seemingly imminent, hostilities when they actually came had found the mercantile community of the United States, for the most part, unbelieving and unprepared. The cry of "Wolf!" had been raised so often that they did not credit its coming, even when at the doors. This was especially the case in New England, where the popular feeling against war increased the indisposition to think it near. On May 14, Captain Bainbridge, commanding the Boston navy yard, wrote: "I am sorry to say that the people here do not believe we are going to war, and are too much disposed to treat our national councils with contempt, and to consider their preparations as electioneering."[499] The presidential election was due in the following November. A Baltimore newspaper of the day, criticising the universal rush to evade the embargo of April 4, instituted in order to keep both seamen and property at home in avoidance of capture, added that in justice it must be said that most people believed that the embargo, as on former occasions, did not mean war.[500]

Under the general sense of unpreparedness, it seemed to many inconceivable that the Administration would venture to expose the coasts to British reprisals. John Randolph, repeating in the House of Representatives in secret session a conversation between the Committee on Foreign Relations and the Secretary of State, said: "He was asked whether any essential changes would be made in the sixty days (of the proposed embargo) in the defence of our maritime frontier and seaports. He replied, pretty considerable preparations would be made. He said New York was in a pretty respectable state, but not such as to resist a formidable fleet; but that it was not to be expected that that kind of war would be carried on." The obvious reply was, "We must expect what commonly happens in wars." "As to the prepared state of the country, the President, in case of a declaration, would not feel bound to take more than his share of the responsibility. The unprepared state of the country was the only reason why ulterior measures should be deferred."[501] Randolph's recollections of this interview were challenged by members of the Committee in other points, but not in these. The Administration had then been in office three years, and the causes of war had been accumulating for at least seven; but so notorious was the unreadiness that a great part of the community even now saw only bluster.

For these reasons the first rush to privateering, although feverishly energetic, was of a somewhat extemporized character. In consequence of the attempt to elude the embargo, by a precipitate and extensive export movement, a very large part of the merchant ships and seamen were now abroad. Hence, in the haste to seize upon enemy's shipping, anything that could be sent to sea at quick notice was utilized. Vessels thus equipped were rarely best fitted for a distant voyage, in which dependence must rest upon their own resources, and upon crews both numerous and capable. They were therefore necessarily directed upon commercial highways near at hand, which, though not intrinsically richest, nor followed by the cargoes that would pay best in the United States, could nevertheless adequately reward enterprise. In the near vicinity of Halifax the routes from the British West Indies to New Brunswick, Nova Scotia, and the St. Lawrence, met and crossed the equally important lines of travel from the British Islands to the same points. This circumstance contributed to the importance of that place as a naval and commercial centre, and also focussed about it by far the larger part of the effort and excitement of the first privateering outburst from the United States. As Rodgers' bold sortie, and disappearance into the unknown with a strong squadron had forced concentration upon the principal British vessels, the cruisers remaining for dispersion in search of privateers were numerically inadequate to suppress the many and scattered Americans. Before Warren's arrival the prizes reported in the United States were one hundred and ninety, and they probably exceeded two hundred. An analysis of the somewhat imperfect data which accompany these returns indicates that about three fourths were seized in the Bay of Fundy and in the off-lying waters from thence round to Newfoundland. Of the remainder, half, probably, were taken in the West Indies; and the rest out in the deep sea, beyond the Gulf Stream, upon the first part of the track followed by the sugar and coffee traders from the West Indies to England.[502] There had not yet been time to hear of prizes taken in Europe, to which comparatively few privateers as yet went.

One of the most intelligent and enterprising of the early privateers was Commodore Joshua Barney, a veteran of the American Navy of the Revolution. He commissioned a Baltimore schooner, the "Rossie," at the outbreak of the war; partly, apparently, in order to show a good example of patriotic energy, but doubtless also through the promptings of a love of adventure, not extinguished by advancing years. The double motive kept him an active, useful, and distinguished public servant throughout the war. His cruise on this occasion, as far as can be gathered from the reports,[503] conformed in direction to the quarters in which the enemy's merchant ships might most surely be expected. Sailing from the Chesapeake July 15, he seems to have stood at once outside the Gulf Stream for the eastern edge of the Banks of Newfoundland. In the ensuing two weeks he was twice chased by an enemy's frigate, and not till July 31 did he take his first prize. From that day, to and including August 9, he captured ten other vessels—eleven in all. Unfortunately, the precise locality of each seizure is not given, but it is inferable from the general tenor of the accounts that they were made between the eastern edge of the Great Banks and the immediate neighborhood of Halifax; in the locality, in fact, to which Hull during those same ten days was directing the "Constitution," partly in pursuit of prizes, equally in search of the enemy's ships of war, which were naturally to be sought at those centres of movement where their national traders accumulated.
