The preliminary steps leading to the war are a diplomatic maze, revealing the double-dealing of the actors, and likewise showing the uncertain position held by the Swiss League in the empire. The destruction of this league, and the overthrow of Charles the Bold were chiefly aimed at. The maze of intrigue is, indeed, well-nigh impenetrable; yet, because the preliminaries are far less known than the wars which followed, and the actual facts have been often distorted, they will, no doubt, command general interest, and we shall try to disentangle the skeins as best we can. The battle of St. Jacques had secured for the Confederates, not only the sympathies of Louis, but also the alliance of his father, Philip the Good, of Burgundy, the Sforzas of Milan, and others. Since those times of prowess the young republic had been growing into a prosperous and powerful nation, not without its influence on continental military affairs. Admired, envied, and feared, by turns, its friendship was greatly appreciated, and it lent protection to all who sought it. So strong was its love of warfare, that it was at all times ready to avenge any wrong or fancied wrong done to itself or its friends. Thus, Zurich, in 1456, laid waste the lands of the Austrian knight-robbers who had plundered some Strasburg merchants on a Swiss round. Despite the distance between them, the two towns of Strasburg and Zurich were on terms of close friendship.[39] At the bidding of Pius II., the elegant Latin writer commonly known as Æneas Sylvius, who had fallen out with his literary friend, Duke Sigmund of Austria, the Eidgenossen conquered Thurgau, which had remained still an Austrian province, and placed it amongst their subject lands. The quarrels of Mulhausen and Schaffhausen with Austria entangled their friends of the league into a war with Sigmund (1468), who, to secure peace, agreed to pay over the sum of ten thousand florins, guaranteeing them their recent conquests. This feud of Waldshut (Black Forest) led to the Burgundian wars.
