It is difficult to decide whether Waldemar foresaw the full danger and bearing of his high-handed step; whether he knew what it meant to plunder a city like Wisby, one of the strongest arms of the Hansa. He had certainly thrown the gauntlet down to the towns; he was quickly to learn that the power which some years ago had successfully beaten his predecessors had but grown in strength since that date.

On the first news of Waldemar's treachery, the Baltic cities laid an embargo on all Danish goods, and then called together a hasty council in which it was decreed that until further notice all intercourse with Denmark should be forbidden on pain of death and loss of property. Then they put themselves into communication with Norway and Sweden in order in the event of a war to secure the alliance of these countries, an assistance that was the more readily promised because their sovereigns were at feud with Waldemar. To defray the war costs it was determined to levy a poundage tax on all Hanseatic exported goods.

A fleet was got ready with all possible speed, and when everything was in order, the towns sent a herald to Waldemar with a formal declaration of war.

In May, 1362, their ships appeared in the Sound, and brilliant success at first attended their arms. Copenhagen was plundered, its church bells carried to Lübeck as the victor's booty. At Scania the cities looked to meet their northern allies, in order in conjunction with them to take possession of the Danish strongholds on the mainland. Here, however, disappointment awaited them. Whether lack of money or fear had deterred the northern kings from keeping their word is unknown; at any rate, they did not put in an appearance with their armies.

The Burgomaster of Lübeck, Johann Wittenborg, who commanded the Hanseatic fleet, saw himself forced to use the men he had on board for the land attack. He held himself the more justified in doing this since he deemed he had so thoroughly routed the Danes, that from the side of the sea there was nothing to be feared.

This decision was rash, and Wittenborg was to atone for it with his life. Already it seemed as if the stronghold Helsingborgs was in his hands—he had been besieging it sixteen days with great catapults—when Waldemar suddenly appeared with his fleet upon the Scanian coast, surprised the Hansa vessels that had been left with but a feeble crew, and carried off twelve of the best ships, and most of their provisions and weapons. The consequence was that Wittenborg saw himself obliged to return with the remnant of his army to Lübeck.

He found the city embittered against him in the highest degree for his defeat; though it saw that the main guilt of the disastrous end of the war lay with the faithless northern kings. The stern free city deemed it right, not only towards itself, but also to its sister towns, to punish heavily the unsuccessful leader. Wittenborg had hardly landed ere he was arrested, chained, and thrown into a dungeon. Here he dragged out a weary year of imprisonment. In vain some of the cities pleaded his cause, in vain his friends tried to obtain his deliverance. Lübeck was a stern mistress, who knew no mercy, and could brook no ill success. In her dictionary, as in that of youth, according to Richelieu in Bulwer's play, there might be no such word as "fail." Wittenborg had, of course, been at once deprived of his burgomagisterial honours; a year after his defeat his head publicly fell under the executioner's axe in the market-place of Lübeck. Burial in the councillors' church was denied him. He was laid to rest in the cloisters of the Dominicans the spot where all criminals were interred in Lübeck during the Middle Ages; the spot where, down to our own era, all criminals passing that way to execution received from the pious monks a soothing drink as last farewell to life. Further, Wittenborg's name is absent from the record of the burgomasters; an omission in this place, which doubtless has the same meaning as the absence of Marino Falieri's portrait among the long row of Doges in the Venetian Palace.

The election of a burgomaster as leader of the troops is quite in character with the spirit of those times. Such trade warriors are not uncommon in the history of the Hansa. Within the roomy stone hall that served as entry and store-room to those ancient dwelling-houses, it was usual to see helmet, armour, and sword hanging up above stores of codfish, barrels of herrings, casks of beer, bales of cloth, or what not besides.

To this day the stranger is shown in the marketplace at Lübeck the stone on which Wittenborg sat before his execution, and in the collection of antiquities is the chair of torture in which he was borne thither. So sternly did the Hansa punish.

There exists an entirely unauthenticated fable that Wittenborg had betrayed his trust in return for a dance with the Queen of Denmark, promising her as a reward the island of Bornholm. That the fable had some currency is proved by the fact that for a long while there survived in Lübeck the expression, "He is dancing away Bornholm," when some one light-heartedly did an unjustifiable deed. The story has given one of the younger German poets, Geibel, the theme for a famous ballad. Further, it was fabled that twice a year the Burgomaster and council of Lübeck solemnly drank Hippokras out of silver cups made from Wittenborg's confiscated property, repeating the while a Low German distich that reminded them of their stern duty and their predecessor's sad fate. Modern accurate research, pitiless in the destruction of picturesque legends has discovered that these cups were not made till the sixteenth century, and were paid for by a tax levied on Bornholm, then in rebellion.
