[Illustration: The Battle of the Baltic, April 2nd, 1801.
From Brenton's Naval History.]

The Sound is narrow and shallow, a mere tangle of shoals wrinkled with twisted channels and scoured by the swift tides. King's Channel runs straight up towards the city, but a huge sandbank, like the point of a toe, splits the channel into two just as it reaches the harbour. The western edge runs up, pocket-shaped, into the city, and forms the actual port; the main channel contracts, swings round to the south-east, and forms a narrow passage between the shallows in front of the city and a huge shoal called the Middle Ground. A cluster of grim and heavily armed fortifications called the Three-Crown Batteries guarded the entrance to the harbour, and looked right up King's Channel; a stretch of floating batteries and line-of-battle ships, a mile and a half in extent, ran from the Three-Crown Batteries along the edge of the shoals in front of the city, with some heavy pile batteries at its termination. The direct approach up King's Channel, together with the narrow passage between the city and the Middle Ground, were thus commanded by the fire of over 600 heavy guns. The Danes had removed the buoys that marked all the channels, the British had no charts, and only the most daring and skilful seamanship could bring the great ships of the British fleet through that treacherous tangle of shoals to the Danish front. As a matter of fact, the heavier ships in the British fleet never attempted to join in the desperate fight which was waged, but hung as mere spectators in the offing.

Meanwhile popular enthusiasm in the Danish capital was at fever-point. Ten thousand disciplined troops manned the batteries; but peasants from the farms, workmen from the factories, merchants from the city, hastened to volunteer, and worked day and night at gun-drill. A thousand students from the university enrolled themselves, and drilled from morning till night. These student-soldiers had probably the best military band ever known; it consisted of the entire orchestra of the Theatre Royal, all volunteers. A Danish officer, sent on some message under a flag of truce to the British fleet, was required to put his message in writing, and was offered a somewhat damaged pen for that purpose. He threw it down with a laugh, saying that "if the British guns were not better pointed than their pens they wouldn't make much impression on Copenhagen." That flash of gallant wit marked the temper of the Danes. They were on flame with confident daring.

Nelson, always keen for a daring policy, had undertaken to attack the Danish defences with a squadron of twelve seventy-fours, and the frigates and bomb-vessels of the fleet. He determined to shun the open way of King's Channel, grope through the uncertain passage called the Dutch Deep, at the back of the Middle Ground, and forcing his way up the narrow channel in front of the shallows, repeat on the anchored batteries and battleships of the Danes the exploit of the Nile. He spent the nights of March 30 and 31 sounding the channel, being himself, in spite of fog and ice, in the boat nearly the whole of these two bitter nights. On April 1 the fleet came slowly up the Dutch Deep, and dropped anchor at night about two miles from the southern extremity of the Danish line. At eleven o'clock that night, Hardy—in whose arms Nelson afterwards died on board the Victory—pushed off from the flagship in a small boat and sounded the channel in front of the Danish floating batteries. So daring was he that he actually sounded round the leading ship of the Danish line, using a pole to avoid being detected.

In the morning the wind blew fair for the channel. Nelson's plans had been elaborated to their minutest details, and the pilots of the fleet were summoned at nine o'clock to the flagship to receive their last instructions. But their nerve failed them. They were simply the mates or masters of Baltic traders turned for the moment into naval pilots. They had no charts. They were accustomed to handle ships of 200 or 300 tons burden, and the task of steering the great British seventy-fours through the labyrinths of shallows, with the tide running like a mill-race, appalled them. At last Murray, in the Edgar, undertook to lead. The signal was made to weigh in succession, and one great ship after another, with its topsails on the caps, rounded the shoulder of the Middle Ground, and in stately procession, the Edgar leading, came up the channel. Campbell in his fine ballad has pictured the scene:—

"Like leviathans afloat
Lay their bulwarks on the brine,
While the sign of battle flew
On the lofty British line.
It was ten of April morn by the chime;
As they drifted on their path
There was silence deep as death,
And the boldest held his breath
For a time.
But the might of England flushed
To anticipate the scene,
And her van the fleeter rushed
O'er the deadly space between."

The leading Danish ships broke into a tempest of fire as the British ships came within range. The Agamemnon failed to weather the shoulder of the Middle Ground, and went ignobly ashore, and the scour of the tide kept her fast there, in spite of the most desperate exertions of her crew. The Bellona, a pile of white canvas above, a double line of curving batteries below, hugged the Middle Ground too closely, and grounded too; and the Russell, following close after her, went ashore in the same manner, with its jib-boom almost touching the Bellona's taffrail. One-fourth of Nelson's force was thus practically out of the fight before a British gun was fired. These were the ships, too, intended to sail past the whole Danish line and engage the Three-Crown Batteries. As they were hors de combat, the frigates of the squadron, under Riou—"the gallant, good Riou" of Campbell's noble lines—had to take the place of the seventy-fours.

Meanwhile, Nelson, in the Elephant, came following hard on the ill-fated Russell. Nelson's orders were that each ship should pass her leader on the starboard side, and had he acted on his own orders, Nelson too would have grounded, with every ship that followed him. The interval betwixt each ship was so narrow that decision had to be instant; and Nelson, judging the water to the larboard of the Russell to be deeper, put his helm a-starboard, and so shot past the Russell on its larboard beam into the true channel, the whole line following his example. That sudden whirl to starboard of the flagship's helm—a flash of brilliant seamanship—saved the battle.

Ship after ship shot past, and anchored, by a cable astern, in its assigned position. The sullen thunder of the guns rolled from end to end of the long line, the flash of the artillery ran in a dance of flame along the mile and a half of batteries, and some 2000 pieces of artillery, most of them of the heaviest calibre, filled the long Sound with the roar of battle. Nelson loved close fighting, and he anchored within a cable's length of the Danish flagship, the pilots refusing to carry the ship nearer on account of the shallow depth, and the average distance of the hostile lines was less than a hundred fathoms. The cannonade raged, deep-voiced, unbroken, and terrible, for three hours. "Warm work," said Nelson, as it seemed to deepen in fury and volume, "but, mark you, I would not be elsewhere for thousands." The carnage was terrific. Twice the Danish flagship took fire, and out of a crew of 336 no fewer than 270 were dead or wounded. Two of the Danish prams drifted from the line, mere wrecks, with cordage in rags, bulwarks riddled, guns dismounted, and decks veritable shambles.

The battle, it must be remembered, raged within easy sight of the city, and roofs and church towers were crowded with spectators. They could see nothing but a low-lying continent of whirling smoke, shaken with the tumult of battle, and scored perpetually, in crimson bars, with the flame of the guns. Above the drifting smoke towered the tops of the British seventy-fours, stately and threatening. The south-east wind presently drove the smoke over the city, and beneath that inky roof, as under the gloom of an eclipse, the crowds of Copenhagen, white-faced with excitement, watched the Homeric fight, in which their sons, and brothers, and husbands were perishing.
