The next day was wasted in despatching a flag of truce to the Governor of Cronenburg Castle, to ask whether he had received orders to fire at the British fleet, as the admiral must consider the first gun to be a declaration of war on the part of Denmark. A soldier-like and becoming answer was returned to this formality. The governor said that the British minister had not been sent away from Copenhagen but had obtained a passport at his own demand. He himself, as a soldier, could not meddle with politics: but he was not at liberty to suffer a fleet—of which the intention was not yet known—to approach the guns of the castle which he had the honour to command, and he requested, if the British admiral should think proper to make any proposals to the King of Denmark, that he might be apprised of it before the fleet approached nearer. During this intercourse a Dane, who came on board the commander's ship, having occasion to express his business in writing found the pen blunt, and, holding it up, sarcastically said, "If your guns are not better pointed than your pens you will make little impression on Copenhagen!"
Nelson, who was now appointed to lead the van, shifted his flag to the Elephant, Captain Foley—a lighter ship than the St. George, and, therefore, fitter for the expected operations. The two following days were calm. Orders had been given to pass the Sound as soon as the wind would permit; and on the afternoon of the 29th the ships were cleared for action with an alacrity characteristic of British seamen. At daybreak on the 30th it blew a top-sail breeze from north-west. The signal was made and the fleet moved on in order of battle; Nelson's division in the van, Sir Hyde's in the centre, and Admiral Graves' in the rear.
The whole force consisted of fifty-one sail of various descriptions, of which sixteen were of the line. The greater part of the bomb and gun vessels took their stations off Cronenburg Castle, to cover the fleet; while others on the larboard were ready to engage the Swedish shore. The Danes, having improved every moment which ill-timed negotiation and baffling weather gave them, had lined their shore with batteries; and as soon as the Monarch, which was the leading ship, came abreast of them a fire was opened from about a hundred pieces of cannon and mortars. Our light vessels immediately in return opened their fire upon the castle. The enemy's shot fell near enough to splash the water on board our ships; not relying upon any forbearance of the Swedes they meant to have kept the mid channel, but when they perceived that not a shot was fired from Helsinburg and that no batteries were to be seen on the Swedish shore, they inclined to that side, so as completely to get out of reach of the Danish guns. The uninterrupted blaze which was kept up from them till the fleet had passed served only to exhilarate our sailors and afford them matter for jest, as the shot fell in showers a full cable's length short of its destined aim.
About mid-day the whole fleet anchored between the island of Huen and Copenhagen. Sir Hyde, with Nelson, Admiral Graves, some of the senior captains, and the commanding officers of the artillery and the troops, then proceeded in a lugger to reconnoitre the enemy's means of defence; a formidable line of ships, radeaux, pontoons, galleys, fire-ships, and gun-boats, flanked and supported by extensive batteries, and occupying, from one extreme point to the other, an extent of nearly four miles.
A council of war was held in the afternoon. Nelson offered his services for the attack, requiring ten sail of the line and the whole of the smaller craft. Sir Hyde gave him two more line-of-battle ships than he asked for and left everything to his judgment.
The enemy's force was not the only, nor the greatest, obstacle with which the British fleet had to contend: there was another to be overcome before they could come in contact with it. The channel was little known and extremely intricate; all the buoys had been removed; and the Danes considered this difficulty as almost insuperable, thinking the channel impracticable for so large a fleet. Nelson himself saw the soundings made and the buoys laid down, boating it upon this exhausting service, day and night, till it was effected. When this was done, he thanked God for having enabled him to get through this difficult part of his duty. "It had worn him down," he said, "and was infinitely more grievous to him than any resistance which he could experience from the enemy."
On the morning of April 1st the whole fleet removed to an anchorage within two leagues of the town and off the north-west end of the Middle Ground: a shoal lying exactly before the town, at about three-quarters of a mile distance, and extending along its whole sea front. The King's Channel, where there is deep water, is between this shoal and the town; and here the Danes had arranged their line of defence, as near the shore as possible: nineteen ships and floating batteries, flanked, at the end nearest the town, by the Crown Batteries, which were two artificial islands at the mouth of the harbour—most formidable works; the larger one having, by the Danish account, sixty-six guns; but, as Nelson believed, eighty-eight. The fleet having anchored, Nelson, with Riou in the Amazon, made his last examination of the ground; and about one o'clock, returning to his own ship, threw out the signal to weigh. It was received with a shout throughout the whole division; they weighed with a light and favourable wind. The narrow channel between the island of Saltholm and the Middle Ground had been accurately buoyed; the small craft pointed out the course distinctly; Riou led the way: the whole division coasted along the outer edge of the shoal, doubled its further extremity, and anchored there off Draco Point, just as the darkness closed—the headmost of the enemy's line not being more than two miles distant. The signal to prepare for action had been made early in the evening; and, as his own anchor dropped, Nelson called out, "I will fight them the moment I have a fair wind." It had been agreed that Sir Hyde, with the remaining ships, should weigh on the following morning, at the same time as Nelson, to menace the Crown Batteries on his side and the four ships of the line which lay at the entrance of the arsenal, and to cover our own disabled ships as they came out of action.
The Danes, meantime, had not been idle: no sooner did the guns of Cronenburg make it known to the whole city that all negotiation was at an end, that the British fleet was passing the Sound, and that the dispute between the two crowns must now be decided by arms, than a spirit displayed itself most honourable to the Danish character. All ranks offered themselves to the service of their country; the university furnished a corps of twelve hundred youths, the flower of Denmark. It was one of those emergencies in which little drilling or discipline is necessary to render courage available: they had nothing to learn but how to manage the guns, and were employed day and night in practising them. When the movements of Nelson's squadron were perceived, it was known when and where the attack was to be expected, and the line of defence was manned indiscriminately by soldiers, sailors, and citizens.
This was an awful night for Copenhagen—far more so than for the British fleet, where the men were accustomed to battle and victory, and had none of those objects before their eyes which render death terrible. Nelson sat down to table with a large party of his officers; he was, as he was ever wont to be when on the eve of action, in high spirits, and drank to a leading wind and to the success of the morrow. After supper they returned to their respective ships, except Riou, who remained to arrange the order of battle with Nelson and Foley, and to draw up instructions: Hardy, meantime, went in a small boat to examine the channel between them and the enemy, approaching so near, that he sounded round their leading ship with a pole, lest the noise of throwing the lead should discover him. The incessant fatigue of body as well as mind which Nelson had undergone during the last three days had so exhausted him that he was earnestly urged to go to his cot; and his old servant, Allen, using that kind of authority which long and affectionate services entitled and enabled him to assume on such occasions, insisted upon his complying. The cot was placed on the floor and he continued to dictate from it. About eleven Hardy returned and reported the practicability of the channel and the depth of water up to the enemy's line. About one the orders were completed; and half a dozen clerks in the foremost cabin proceeded to transcribe them, Nelson frequently calling out to them from his cot to hasten their work, for the wind was becoming fair. Instead of attempting to get a few hours of sleep he was constantly receiving reports on this important point. At daybreak it was announced as becoming perfectly fair. The clerks finished their work about six. Nelson, who was already up, breakfasted, and made signal for all captains.
