"This was another of those stipulations which inevitably lead to trouble, for it afforded to Denmark a pretext for continual complaint and interference. When Frederick the Fourth succeeded his father as Duke of Holstein, in 1694, the quarrel grew so hot that Denmark would have invaded Holstein, had not the parties to the Treaty of '89 interfered, and brought about a conference. This lasted all through the year 1696, but the negotiators appointed to settle the matter were unable to arrive at any conclusion.

"The following year, Charles of Sweden, who had just succeeded his father, furnished the duke with some troops, to help him to build some forts that were intended to protect the frontier, in case of invasion by Denmark. Christian of Denmark at once attacked and captured these forts, and levelled them to the ground. The duke, being too weak to engage in a war with his powerful neighbour, did not resent this attack, and the negotiations were continued as before. In view of the danger of the situation, and the necessity for a monarch at the head of affairs, the Swedish Diet met, at Stockholm, to take part in the funeral of the late king, which was to be performed on the 24th of November, and to deliberate upon the situation.

"By the will of the late king, Charles was not to ascend the throne until he reached the age of eighteen, but the diet passed a vote overruling this, and, as the regency concurred, he was at once crowned, and the alliance with Holstein was cemented by the marriage, that had been previously arranged between Charles's eldest sister and the Duke of Holstein, being celebrated at Stockholm. Charles the Twelfth at once concluded treaties with France, England, and Holland; while Denmark is reported to have prepared for war by making a secret alliance with Augustus of Saxony, King of Poland, and the Czar of Russia. Both these monarchs were doubtless desirous of extending their dominions, at the cost of Sweden, whose continental possessions are considerable.

"Augustus is not yet very firmly seated on the throne of Poland. There are several parties opposed to him, and these united in obtaining, from the diet, a refusal to pay the Saxon troops Augustus had brought with him. The king, no doubt, considered that these could be employed for the conquest of Livonia, and that the addition of so large a territory to Poland would so add to his popularity, that he would have no further troubles in his kingdom.

"Charles the Twelfth, being in ignorance of this secret agreement, sent an embassy to Russia, to announce his accession to the throne. The ambassadors were kept a long time waiting for an audience, as the czar was bringing a war with the Turks to a conclusion, and did not wish to throw off the mask until he was free to use his whole force against Sweden. The ambassadors were, at last, received civilly, but the czar evaded taking the usual oaths of friendship, and, after long delays, the embassy returned to Sweden, feeling somewhat disquieted as to the intentions of the czar, but having no sure knowledge of them.

"The King of Poland was more successful in disguising his leaning towards Denmark, sending the warmest assurances to Charles, requesting him to act as mediator in the quarrel between himself and the Duke of Brandenburg, and signing a treaty of alliance with Sweden. But, while Sweden had no idea of the triple alliance that had been formed against her, the intention of Denmark to make war was evident enough, for King Christian was gathering a great naval armament.

"The Duke of Holstein, becoming much alarmed at these preparations, hastened on the fortifications of Tonningen, on the Eider, three leagues from its mouth. The garrison of the place was a weak one, and a thousand Swedish troops were thrown in to strengthen it. The King of Denmark complained that this was a breach of the treaty, but, as his own preparations for war were unmistakable, no one could blame the Duke of Holstein for taking steps to defend his territories.

"As you know, Christian of Denmark died about this time, and was succeeded by his son Frederick the Fourth.

"Last August, he commenced the war, by sending a naval squadron to cover the passage of four regiments into Pomerania. Charles of Sweden, seeing that Holstein must be crushed by its powerful neighbour, called upon Holland and the Duke of Lunenburg, who were with Sweden guarantors of the treaty, to enforce its provisions; and a joint protest was sent to the King of Denmark, who was informed that, if he invaded Holstein, they should consider it a breach of the Treaty of Altena, and treat him as a common enemy. Frederick replied by sending some troops into the duchy.

"No active operations took place, until the beginning of this year. Up to that time, Sweden had not doubted the friendship of the King of Poland, and Charles, at first, could hardly believe the reports he received from the governor of Livonia, that the Saxon troops were approaching the frontier.
