The sun shone fair upon the blue waters as the great fleet of thirty-odd fighting ships sailed up from the south. From the city’s walls and towers a mighty multitude watched it come, unmindful of peril from shot and shell; the Danish line was not half a mile away. In the churches whose bells were still ringing when the first gun was fired from the block-ship _Prövestenen_, the old men and women prayed through the long day, for there were few homes in Copenhagen that did not have son, brother, or friend fighting out there. A single gun answered the challenge, now two and three at once, then broadside crashed upon broadside with deafening roar. When at length all was quiet a tremendous report shook the city. It was the flag-ship _Dannebrog_ that blew up. She was on fire with only three serviceable guns left when she struck her colors, but no ship of her name might sail with an enemy’s prize crew on board, and she did not. The story of that bloody day has been told many times. Briton and Dane hoist their flags on April 2 with equal right, for never was challenge met with more dauntless valor. Lord Nelson owned that of all the hundred and five battles he had fought this was hottest. On the _Monarch_, which for hours was under the most galling fire from the Danish ships, two hundred and twenty of the crew were killed or wounded. “There was not a single man standing,” wrote a young officer on board of her, “the whole way from the mainmast forward, a district containing eight guns a side, some of which were run out ready for firing, others lay dismounted, and others remained as they were after recoiling.... I hastened down the fore ladder to the lower deck and felt really relieved to find somebody alive.” The slaughter on the Danish ships was even greater. More than one-fifth of their entire strength of a little over five thousand men were slain or wounded. Of the eighteen hulls they lost thirteen, but only one were the British able to take home with them. The rest were literally shot to pieces and were burned where they lay. As one after another was silenced, those yet alive on board spiked their last guns, if indeed there were any left worth the trouble, threw their powder overboard and made, for the shore. Twice the Danish Admiral abandoned his burning ship, the last time taking up his post in the island battery Tre Kroner. Each time one of the old hulls was crushed, a Briton pushed into the hole made in the line and raked the remaining ones fore and aft until their decks were like huge shambles. The block-ship _Indfödsretten_ bore the concentrated fire of five frigates and two smaller vessels throughout most of the battle. Her chief was killed. When the news reached head-quarters on shore, Captain von Schrödersee, an old naval officer who had been retired because of ill health, volunteered to take his place. He was rowed out, but as he came over the side of the ship a cannon-ball cut him in two.
