which had been greatly interrupted by the war.

The Swedish army was now reinforced by ten thousand Hessians, which the
Landgrave of Casse commanded. Gustavus Adolphus had already invested
Koenigstein; Kostheim and Floersheim surrendered after a short siege; he
was in command of the Maine; and transports were preparing with all
speed at Hoechst to carry his troops across the Rhine. These
preparations filled the Elector of Mentz, Anselm Casimir, with
consternation; and he no longer doubted but that the storm of war would

necessary for the enemy to secure them, while the fertility afforded an
irresistible temptation to a necessitous army. Miscalculating his own
strength and that of his adversaries, the Elector flattered himself that
he was able to repel force by force, and weary out the valour of the
Swedes by the strength of his fortresses. He ordered the fortifications
of his capital to be repaired with all diligence, provided it with every

garrison of 2,000 Spaniards, under Don Philip de Sylva. To prevent the
approach of the Swedish transports, he endeavoured to close the mouth of
the Maine by driving piles, and sinking large heaps of stones and
vessels. He himself, however, accompanied by the Bishop of Worms, and
carrying with him his most precious effects, took refuge in Cologne, and
abandoned his capital and territories to the rapacity of a tyrannical

than of weak and overweening confidence, did not prevent the Swedes from
marching against Mentz, and making serious preparations for an attack
upon the city. While one body of their troops poured into the Rheingau,
