The Cattegat is divided from the Baltic by the Danish islands, between the east coast of the Cimbric peninsula in the neighbourhood of the German frontier and south-western Sweden.
Denmark, however, is nowhere low in the sense in which Holland is; the country is pleasantly diversified, and rises a little at the coast even though it remains flat inland.
In 1713 the regent broke the stipulated neutrality of the duchy in favour of Sweden and Frederick IV.
The negotiations broke down, however, on the refusal of Denmark to yield the principle of the indissoluble union with the Danish crown; on the 23rd of February the truce was at an end, and on the 3rd of April the war was renewed.
Denmark replied with a refusal to recognize the right of any foreign power to interfere in her relations with Schleswig; to which Austria, anxious to conciliate the smaller German princes, responded with a vigorous protest against Danish infringements of the compact of 1852.
