There was another controlling reason why short range favored the British against the Americans. The schooners of the latter, not being built for war, carried their guns on a deck unprotected by bulwarks. The men, being exposed from the feet up, could be swept away by canister, which is a quantity of small iron balls packed in a case and fired from a cannon. When discharged, these separate and spread like buckshot, striking many in a group. They can maim or kill a man, but their range is short and penetrative power small. A bulwarked vessel was, so to say, armored against canister; for it makes no difference whether the protection is six inches of wood or ten of iron, provided it keeps out the projectile. The American schooners were in this respect wholly vulnerable.

Over-insistence upon details of advantage or disadvantage is often wearisome, and may be pushed to pettifogging; but these quoted are general and fundamental. To mention them is not to chaffer over details, but to state principles. There is one other which should be noted, although its value may be differently estimated. Of the great long-gun superiority of the Americans more than one half was in the unprotected schooners; distributed, that is, among several vessels not built for war, and not capable of acting well together, so as to concentrate their fire. There is no equality between ten guns in five such vessels and the same ten concentrated on one deck, under one captain. That this is not special pleading, to contravene the assertion advanced by James of great American superiority on Ontario, I may quote words of my own, written years ago with reference to a British officer: "An attempt was made to disparage Howe's conduct (in 1778), and to prove that his force was even superior to that of the French, by adding together the guns in all his ships, disregarding their classes, or by combining groups of his small vessels against D'Estaing's larger units. For this kind of professional arithmetic Howe felt and expressed just and utter contempt."⁷⁰ So Nelson wrote to the commander of a British cruising squadron, "Your intentions of attacking the 'Aigle'"—a seventy-four—"with your three frigates are certainly very laudable, but I do not consider your force by any means equal to it." The new American ship, the "General Pike," possessed this advantage of the seventy-four. One discharge of her broadside was substantially equal to that of the ten schooners, and all her guns were long; entirely out-ranging the batteries of her antagonists. Under some circumstances—a good breeze and the windward position—she was doubtless able to encounter and beat the whole British squadron on Ontario. But the American schooners were mere gunboats, called to act in conditions unfavorable to that class of vessel, the record of which for efficiency is under no circumstances satisfactory.

After leaving Sackett's, Chauncey showed himself off Kingston and then went up the lake, arriving off Niagara on the evening of July 27. An abortive attempt, in conjunction with the army, was made upon a position of the enemy at Burlington Heights, then far in rear of his main line; but it being found too strong, the fleet, with the troops still on board, bore over to York and there retaliated the injury done by Yeo at Genesee and Sodus. There was no opposition; many stores were destroyed or brought away, some military buildings burned, and the vessels then returned to Niagara. They were lying there at daybreak of August 7 when the British appeared: two ships, two brigs, and two large schooners. Chauncey had substantially his whole force: two ships, the "Pike" and "Madison," the brig "Oneida," and ten schooners. He got under way shortly and put out into the lake. Various manœuvres followed, his principal object being to get to windward of the enemy; or, when the wind failed, to sweep⁷¹ the schooners close enough for their long guns to reach; the only useful function they possessed. These efforts were unsuccessful, and night shut in with the two opponents sailing in parallel lines, heading north, with the wind at west; the Americans to leeward and in rear of the British. At two in the morning, in a heavy squall, two schooners upset, with the loss of all on board save sixteen souls. Chauncey reckoned these to be among his best, and, as they together mounted nineteen guns, he considered that "this accident gave the enemy decidedly the superiority"; another instance of faulty professional arithmetic, omitting from the account the concentration of power in the "General Pike."

Yeo did not estimate conditions in the same way, and persisted warily in keeping the weather gage, watching for a chance to cut off schooners, or for other favoring opportunity; while Chauncey as diligently sought to gain the advantage of the wind, to force action with his heavy ships. Manœuvring continued all day of the 8th, 9th, and 10th. The winds, being light and shifting, favored now one, now the other; but in no case for long enough to insure a meeting which the American with good reason desired, and his antagonist with equal propriety would accept only under conditions that suited him. At nine in the evening of August 10 the American squadron was standing northwest, with the wind at southwest, when the British, which was then following to windward, wore and stood south. Chauncey made no change in direction, but kept his vessels in two lines; this being the order of battle by which, not being able to attack himself, he hoped to induce Yeo to engage incautiously. The six smallest schooners, of the eight now left to him, were put in the weather line; therefore toward the enemy, if he persisted in keeping to windward. The lee line, abreast of the other, and six hundred yards from it, was composed of the "Pike," "Madison," and "Oneida," astern of which were the two heaviest schooners. The smaller vessels were displayed as a tempting bait, disposed, as it were, in such manner that the opponent might hope to lay hands on one or more, without coming too much under the "Pike's" heavy guns; for her two larger consorts, carrying carronades chiefly, might be neglected at the distance named. If such an attempt were made, the schooners' orders were to edge imperceptibly to leeward, enticing the enemy to follow in his eagerness; and when he was near enough they were to slip cleverly through the intervals in the lee line, leaving it to finish the business. The lure was perhaps a little too obvious, the enemy's innocent forgetfulness of the dangers to leeward too easily presumed; for a ship does not get out of the hold of a clear-headed captain as a mob of troops in hot pursuit may at times escape the control of their officers. In view, however, of Yeo's evident determination to keep his "fleet in being," by avoiding action except on his own terms, nothing better was open to Chauncey, unless fortune should favor him.

At half-past ten the British again wore, now standing northwest after the American squadron, the rear vessels of which opened fire at eleven (A). At quarter-past eleven the cannonade became general between the enemy and the weather line (B). Fifteen minutes later, the four rear schooners of the latter, which were overmatched when once within carronade range, bore up and ran to leeward; two taking position on the other side of the main division, and two astern of it (c, c). So far all went according to plan; but unhappily the leading two American schooners, instead of keeping away in obedience to orders, tacked—went about towards the enemy—keeping to windward (d). Chauncey, seeing the risk involved for them, but prepossessed with the idea of luring Yeo down by the appearance of flight set by the schooners, made what can scarcely be considered other than the mistake of keeping away himself, with the heavy ships; "filled the maintopsail, and edged away two points, to lead the enemy down, not only to engage him to more advantage, but to lead him away from the 'Growler' and 'Julia'" (C). Yeo, equally dominated by a preconceived purpose not to bring his ships under the guns of the "Pike," acted much as a squirrel would do with two nuts in sight; he went for the one safely distant from suspected danger. "He kept his wind," reported Chauncey, "until he had completely separated those two vessels from the rest of the squadron, exchanged a few shot with the 'Pike,' as he passed, without injury to us, and made sail after the two schooners" (e). Some time after midnight these surrendered to odds plainly irresistible.⁷²

The tacking of the two schooners was an act as ill-judged as it was insubordinate, for which Chauncey was in no wise responsible. His bearing up was certainly an error, which unfortunately lent itself to the statement, contemporaneously made by an American paper, that he retreated, leaving the two vessels to their fate. It was possible, therefore, for Sir James to word the transaction as he airily did: "At eleven we came within gunshot of their line of schooners, which opened a heavy fire, their ships keeping off the wind to prevent our closing. At half-past twelve this ship came within gunshot of the 'Pike' and 'Madison,' when they immediately bore up, fired their stern chase-guns, and made sail for Niagara, leaving two of their schooners astern, which we captured."⁷³ This gives a more victorious and dashing air to the success than it quite deserves. As it stood, it was real enough, though trivial. To take two vessels from a superior fleet, within range of its commander-in-chief, is a handsome business, which should not need to be embellished by the implication that a greatly desired fight could not be had. To quote Marryat, "It is very hard to come at the real truth of this sort of thing, as I found out during the time that I was in his Majesty's service." Chauncey's version is perfectly probable. Seeing that the enemy would not follow, "tacked and stood after him. At twelve (midnight), finding that I must either separate from the rest of the squadron, or relinquish the hope of saving the two which had separated, I reluctantly gave up the pursuit." His reading of Yeo's conduct is plausible. "From what I have been able to discover of the movements of the enemy, he has no intention of engaging us, except he can get decidedly the advantage of wind and weather; and as his vessels in squadron sail better than our squadron, he can always avoid an action.... He thinks to cut off our small dull sailing schooners in detail." Here and always Chauncey's conduct reflects the caution prescribed in his instructions to Perry, rather than the resolute determination the latter showed to bring matters to an issue. On the other hand, it is to be remembered that, owing to the nearly equal facilities for ship-building—for replacing ships lost—possessed by Kingston and Sackett's, a decisive naval victory would not have the finality of result to be expected on Lake Erie. Contrary to the usual conditions of naval war, the two ports, not the fleets dependent on them, were the decisive elements of the Ontario campaign; and the ignoring of that truth was the fundamental, irremediable, American error.

PLAN OF CHAUNCEY'S ENGAGEMENT AUGUST 10, 1813

Chauncey returned to Sackett's on August 13, provisioned the squadron for five weeks, and sailed the same evening. On the 16th he was back off Niagara, and there again sighted the enemy; but a heavy westerly gale drove both squadrons to the lower end of the lake, where each entered its own harbor on the 19th. August 29 the American put out again, having an additional newly built schooner, named the "Sylph," large and fast, carrying three or four long 32-pounders. Chauncey reported that he had now nine vessels with ninety-one guns, but that the enemy was still superior. In number of guns, possibly; but it is difficult to accept the statement otherwise, except in the one very important particular of squadron manœuvring power. This enabled Yeo to avoid action, except when it suited him to fight; or unless Chauncey was willing to engage first with part only of his squadron, following it with the rest. Such advantage in manœuvring greatly increases the ability of the inferior to serve his own cause, but it does not constitute superiority. The delusion of measuring force by guns, irrespective of the ships that carry them, has been explained.

Yeo's intermediate movements do not appear, but on September 7 the antagonists again met off the Niagara River. From that day till the 12th the American fleet endeavored to force a general action, which the other steadily, and properly, refused. The persistent efforts of the one to close, and of the other to avoid, led to a movement round the lake, ending by the British entering Amherst Bay, five miles west of Kingston. On one occasion, off the Genesee on September 11, a westerly breeze carried the United States squadron within three-quarters of a mile of the enemy, before the latter felt it. A cannonade and pursuit of some hours followed, but without decisive result. There seems traceable throughout Chauncey's account a distinct indisposition to what is called technically "a general chase;" to press on with part of the squadron, trusting to the slower vessels coming up soon enough to complete the work of the faster. He was unwilling thus to let his fleet loose. "This ship" (the "General Pike"), "the 'Madison,' and the 'Sylph,' have each a schooner constantly in tow, yet the others cannot sail as fast as the enemy's squadron, which gives him decidedly the advantage, and puts it in his power to engage me when and how he chooses." In such a situation success can be had only by throwing the more rapid upon the enemy as an advance guard, engaging as they get within range, relying upon their effecting such detention that the others can arrive in time to their support. To this recourse, though in halting fashion, Chauncey finally came on what proved to be his last collision with Yeo, September 28.

CHAPTER XI
THE CAMPAIGN OF 1813 ON THE LAKES AND NORTHERN FRONTIER. THE BATTLE OF LAKE ERIE

While the movements last related in the preceding chapter were in progress, the contest for Lake Erie was brought to a final decision. After the successful transfer of the vessels from Black Rock to Erie, June 18, Perry remained upon the upper lake superintending all administrative work; but in particular pressing the equipment of the two brigs ordered by Chauncey the previous winter. To one of these, on which Perry intended to embark his own fortunes, was given the name of "Lawrence," the captain of the "Chesapeake," whose death, heroic in defeat, occurred at this period. The other was called the "Niagara." They were sister vessels, of five hundred tons, constructed for war, and brig-rigged; that is, with two masts, and carrying square sails on both. Their armaments also were alike; eighteen 32-pounder carronades, and two long 12-pounder guns. They were thus about equivalent in fighting force to the ocean sloops-of-war, "Wasp" and "Hornet," which, however, were three-masted. The remainder of the force would now be called a scratch lot. Three were schooner-rigged gunboats, built for the navy at Erie; the remainder were the vessels brought from Black Rock. Of these, one was the brig "Caledonia," formerly British, captured by Elliott the previous autumn; the others were purchased lake craft. When finally taking the lake, August 6, the squadron consisted of the two brigs, of the Black Rock division,—"Caledonia," "Somers," "Tigress," "Ohio," and "Trippe,"—and of three other schooners,—"Ariel," "Scorpion," and "Porcupine,"—apparently those built at Erie; ten sail, all of which, except the "Ohio," were in the final decisive battle.

On July 23 the vessels were rigged, armed, and ready for service, but there were not men enough to man them. How little exacting Perry was in this matter, and how eager to enter upon active operations, is shown by a letter from his superior, Chauncey, to the Secretary of the Navy, dated July 8: "I am at a loss," he says, "to account for the change in Captain Perry's sentiments with respect to the number of men required for the little fleet at Presqu' Isle; for when I parted with him on the last of May, we coincided in opinion perfectly as to the number required for each vessel, which was one hundred and eighty for each of the new brigs, sixty for the 'Caledonia,' and forty for each of the other vessels, making in all seven hundred and forty officers and men. But if Captain Perry can beat the enemy with half that number, no one will feel more happy than myself."⁷⁴ Chauncey having supreme control over both lakes, all re-enforcements from the seaboard were sent to him; and as he had his own particular enemy on Ontario to confront, it was evident, and natural, that Perry would be least well served. Hence, after successive disappointments, and being of more venturous temper than his superior, it is not surprising that he soon was willing to undertake his task with fewer men than his unbiased judgment would call necessary.

The clash of interests between the two squadrons, having a common superior but separate responsibilities, is seen by a comparison of dates, which shows operations nearly simultaneous. On July 23 the Erie squadron was reported "all ready to meet the enemy the moment they are officered and manned;" on July 20 the "General Pike" was ready, and on the 21st the Ontario squadron sailed from Sackett's Harbor. On August 5 Perry had his vessels across the bar at Erie, and next day stood out into the lake. On the 7th Chauncey and Yeo met for their first encounter. On the 8th the two Ontario schooners, "Hamilton" and "Scourge," were lost with nearly all on board; and on the 10th the "Julia" and "Growler" were captured. After this, it may be imagined that Chauncey with difficulty parted with men; and in the midst of his second collision with Yeo the battle of Lake Erie occurred. In it, of the one hundred and eighty men deemed necessary by Chauncey, Perry's brig had one hundred and forty-two, of whom thirty were sick; while the squadron, with nearly all its vessels present, instead of the intended seven hundred and forty, had but four hundred and ninety. Of this total, nearly one hundred were received from the army on August 31, only nine days before the action. For the most part these were strangers to shipboard. Barring them, Perry's fighting force was barely more than half that required by Chauncey's estimate.

Indirectly, and notwithstanding Perry's disposition to make the best of his difficulty, this condition came near causing his withdrawal from the lake service; a loss which, had it occurred, might have reversed the issues, for in few general actions has the personality of the commander counted for so much, after the battle joined. In a letter of July 26 to Chauncey, he had written: "The men that came by Mr. Champlin are a motley set, blacks, soldiers, and boys. I cannot think you saw them after they were selected."⁷⁵ Chauncey replied, somewhat testily, "I regret you are not pleased with the men sent you; for, to my knowledge, a part of them are not surpassed by any seamen we have in the fleet; and I have yet to learn that the color of the skin, or the cut and trimmings of the coat, can affect a man's qualifications or usefulness." To this he added a warning not much short of a reproof: "As you have assured the secretary that you should conceive yourself equal or superior to the enemy, with a force in men so much less than I had deemed necessary, there will be a great deal expected from you by your country, and I trust they will not be disappointed in the high expectations formed of your gallantry and judgment. I will barely make an observation, which was impressed upon my mind by an old soldier; that is, 'Never despise your enemy.'"⁷⁶

This advice was sound, rightly weighed. Yet it is not too much to say that the confidence which carried Perry on to decisive victory has in it inevitably something of that assurance of success which is akin to contempt of the enemy, and that it was the precise quality in which Chauncey, throughout his own career on the lakes, showed himself deficient, and consequently failed. His plan at that moment, as he himself said in a letter to Perry of July 14, was "to seek a meeting with Sir James Yeo as soon as possible, in order to decide the fate of this lake, and join you immediately after." This was an intelligent project: to beat one enemy first, and then carry his force over to beat the other; but never, when in presence of his antagonist, could he despise him sufficiently to cut his gunboats adrift, and throw one or two vessels into the midst of the fire, as Perry rushed his own ship in, had her cut to pieces,—and won. It is even worse to respect your enemy too greatly than to despise him. Said Farragut, speaking of an officer he highly valued: "Drayton does not know fear, but he believes in acting as if the enemy never can be caught unprepared; whereas I believe in judging him by ourselves, and my motto in action is, 'L'audace, et encore de l'audace, et toujours de l'audace!'" This described Perry in battle.

Although Chauncey closed with expressions of confidence which might be considered conciliatory, Perry experienced an annoyance which was natural, though excessive. He was only twenty-eight, quick of temper, though amiable, and somewhat prone to see more offence than was intended. When the letter reached him, the squadron had just crossed the bar; the most critical movement of the campaign, had the enemy been duly watchful. Having accomplished this, he had before him only the common vicissitudes of naval warfare. Nevertheless, under his first impulse of resentment, he applied to be removed from the station,⁷⁷ giving as his reason, not the quality of men sent, concerning which indeed he had said, "I am pleased to see anything in the shape of a man," but that "I cannot serve under an officer who has been so totally regardless of my feelings." He then summarized the difficulties with which he had contended, and added, "The critical state of General Harrison was such that I took upon myself the responsibility of going out with the few young officers you had been pleased to send me," (Elliott, the second in command, did not arrive till the squadron was over the bar), "with the few seamen I had, and as many volunteers as I could muster from the militia. I did not shrink from this responsibility; but, Sir, at that very moment I surely did not anticipate the receipt of a letter in every line of which is an insult." He then renewed his request. "I am willing to forego that reward which I have considered for two months past almost within my grasp." Fortunately for the renown of the service, from which one of its finest actions might have been lost, it was impossible to grant his application until after the battle had made the question of the command on Lake Erie one of very minor importance. The secretary replied to him with words in which rebuke and appreciation were aptly blended. "A change of commander, under existing circumstances, is equally inadmissible as it respects the interest of the service and your own reputation. It is right that you should reap the harvest which you have sown."⁷⁸

After the Frenchtown disaster⁷⁹ of January 22, 1813, the Army of the Northwest under General Harrison had remained strictly on the defensive throughout the spring and summer. The tenure of its position on the Maumee River depended upon Fort Meigs, built during the winter just above the Rapids, some twenty miles from the lake. Thirty miles east of Meigs was Fort Stephenson at the mouth of the Sandusky River, protecting the approaches to Sandusky Bay, near which were Harrison's headquarters at the time Perry's squadron was ready to move. Fort Stephenson by its situation contributed also to secure the communications of the Maumee line with Central Ohio, and was an obstacle to an enemy's approach by land to Erie, a hundred and fifty miles further east. It was not, however, a work permanent in character, like Meigs; and neither post could be considered secure, because inadequately garrisoned. Fortunately, the general tenor of the instructions received by Procter from Prevost conspired with his own natural character to indispose him to energetic measures. His force of regulars was small; and he had not the faculty, which occasional white men have shown, to arouse vigorous and sustained activity in the Indians, of whom he had an abundance at call. The use of them in desultory guerilla warfare, which was prescribed to him by Prevost, became in his hands ineffective. Nevertheless, from the number known to be under his command, and the control of the water enabling him to land where he would, the threat of savage warfare hung over the frontier like a pall, until finally dissipated by Perry's victory.

The danger to British control of the water, and thereby to the maintenance of their position in the northwest, if the American fleet now building should succeed in getting upon the lake, was perfectly apparent, and made Erie a third and principal point of interest. At the time of Perry's arrival, March 27, the place was entirely defenceless, and without any organization for defence, although the keels of the two brigs were laid, and the three gunboats well advanced in construction. By a visit to Pittsburgh he obtained from an army ordnance officer four small guns, with some muskets; and upon his application the local commander of Pennsylvania militia stationed at Erie five hundred men, who remained till the vessels crossed the bar. Under this slender protection went on the arduous work of building and equipping a squadron in what was substantially a wilderness, to which most of the mechanics and material had to be brought half a thousand miles from the seaboard, under the difficulties of transport in those days. The rapid advance in the preparations aroused the disquietude of the British, but Procter had not the enterprising temper to throw all upon the hazard, for the sake of destroying an armament which, if completed, might destroy him; while the British inferiority of force on Lake Ontario and the Niagara peninsula, together with the movement of Chauncey and Dearborn resulting in the capture of York, April 27, effectually prevented intervention from that quarter in the affairs of Lake Erie. At this time Procter made his first effort of the season, directed against Fort Meigs, which he held besieged for over a week,—from May 1 to May 9. Although unable to capture it, the mismanagement of an American relief force enabled him to inflict a very severe loss; a corps of eight hundred and sixty-six men being cut to pieces or captured, only one hundred and seventy escaping. The chief points of interest in this business are the demonstration of the weakness of the American frontier,—the principal defence of which was thus not merely braved but threatened,—and the effect of control of the water. By it Procter brought over gunboats which ascended the river, and guns of a weight not to be transported by land. The lake also secured his communications.

After the failure before Meigs, Procter turned his attention more seriously to the situation at Erie, and demanded re-enforcements to enable him to attack the place.⁸⁰ Prevost, being commander-in-chief for all Canada, recognized the expediency of the move, and wrote him, June 20, that he had directed General De Rottenburg at Niagara, to push on re-enforcements and supplies; but Prevost was in Kingston, and De Rottenburg, immediately responsible for Niagara, wrote declining to weaken his force. He was already inferior to the United States army under Boyd, which was then confronting him, resting upon Fort George; and there was the prospect also that Chauncey might regain control of the lake. Instead of co-operation for offence, he transmitted arrangements for retreat in case of a disaster to Yeo on Ontario. Procter enclosed this letter to the commander-in-chief, remarking pathetically that he was fully confident of receiving aid from him, but intentions were of no avail. Had the force ordered been sent, he felt sure of destroying the fleet at Erie, thus securing the command of the lake, which would have benefited also the centre [Niagara] division. He should now, he said, make an attempt upon Sandusky; Erie was impossible without re-enforcements. At the same time, July 13, Captain Barclay was about to sail for Long Point, on the Canada shore directly opposite Erie, to embark one hundred troops, and then to endeavor to retain the American fleet in port until the required assistance could be sent. The new British ship "Detroit" was nearly ready for launching at Amherstburg, and could be equipped and gunned there; but seamen were absolutely needed.

In accordance with these plans Barclay went with his squadron to Long Point. There the desired soldiers were refused him; and, as also no seamen were forthcoming, he wrote on July 16 a letter directly to Sir George Prevost, "lest Sir James Yeo should be on the lake," representing the critical state of affairs, owing to the inadequate equipment of his vessels, the want of seamen, and the advanced preparations of the Americans to put afloat a force superior to his. July 20 he appeared off Erie, where Perry's fleet was still in the harbor, waiting for men. How imminent the exposure of the American flotilla at that moment, and how great the British opportunity, appears from the recently published memoirs of a prominent resident.⁸¹ "An English fleet of five vessels of war was at that time cruising off the harbor, in full view. That fleet might at any time have sent in its boats during a dark night, and the destruction of the whole American fleet was almost inevitable; for Perry's force was totally inadequate to its defence, and the regiment of Pennsylvania militia, stationed at Erie expressly for the defence of the fleet, refused to keep guard at night on board. 'I told the boys to go, Captain,' said the worthless colonel of the regiment, 'but the boys won't go.'" Like American merchant ships, American militia obeyed or disobeyed as they pleased. Two hundred soldiers, loaned by Dearborn when the Black Rock flotilla came round, had been recalled July 10. On the 23d and 30th re-enforcements were received from Chauncey, in all one hundred and thirty men. With these, and some landsmen enlisted on the spot for four months, the force of the squadron, estimated to require seven hundred and forty men, was raised to three hundred; but having lately received two pressing letters from the Navy Department, urging General Harrison's critical need of co-operation, Perry determined to go out. Most opportunely for his purpose, Barclay disappeared on the 30th, Friday, which thus for him made good its title to "unlucky." He was absent until August 4, and was by the Americans believed to have gone to Long Point. Before his Court Martial he merely stated that "I blockaded as closely as I could, until I one morning saw the whole of the enemy's force over the bar, and in a most formidable state of preparation." The Court did not press inquiry on the point, which perhaps lay beyond its instructions; but the double failure, to intercept the Black Rock division on its way to Erie,⁸² and to prevent the crossing of the bar, were serious strategic misadventures when confronting superior numbers. Perry's preparations for the passage had been for some time completed, but information of contemplated movements travelled so easily from shore to shore that he gave no indication of immediate action until Sunday. On that day the officers were permitted to disperse in town as usual, but afterwards were hastily summoned back, and the vessels moved down to the bar, on which the depth ordinarily was from five to seven feet, much less than needed for the "Lawrence" and "Niagara." This obstacle, hitherto a protection against naval attack, now imposed an extremely critical operation; for to get over, the brigs must be lightened of their guns and their hulls lifted upon floats. So situated, they were helplessly exposed to destruction, as far as their own powers went.
