f his bravest
soldiers. But notwithstanding, the Swedes continually gained ground,
and had at last advanced so close to the ditch that they prepared
seriously for storming the place. The courage of the besieged now began
to droop. They trembled before the furious impetuosity of the Swedish
soldiers, of which Marienberg, in Wurtzburg, had afforded so fearful an
example. The same dreadful fate awaited Mentz, if taken by storm; and
the enemy might even be easily tempted to revenge the carnage of
Magdeburg on this rich and magnificent residence of a Roman Catholic
prince. To save the town, rather than their own lives, the Spanish
garrison capitulated on the fourth day, and obtained from the
magnanimity of Gustavus a safe conduct to Luxembourg; the greater part
of them, however, following the example of many others, enlisted in the
service of Sweden.

On the 13th December, 1631, the king made his entry into the conquered
town, and fixed his quarters in the palace of the Elector. Eighty
pieces of cannon fell into his hands, and the citizens were obliged to
redeem their property from pillage, by a payment of 80,000 florins. The
benefits of this redemption did not extend to the Jews and the clergy,
who were obliged to make large and separate contributions for
themselves. The library of the Elector was seized by the king as his
share, and presented by him to his chancellor, Oxenstiern, who intended
it for the Academy of Westerrah, but the vessel in which it was shipped
to Sweden foundered at sea.

After the loss of Mentz, misfortune still pursued the Spaniards on the
Rhine. Shortly before the capture of that city, the Landgrave of Hesse
Cassel had taken Falkenstein and Reifenberg, and the fortress of
Koningstein surrendered to the Hessians. The Rhinegrave, Otto Louis,
one of the king's generals, defeated nine Spanish squadrons who were on
their march for Frankenthal, and made himself master of the most
important towns upon the Rhine, from Boppart to Bacharach. After the
capture of the fortress of Braunfels, which was effected by the Count of
Wetterau, with the co-operation of the Swedes, the Spaniards quickly
lost every place in Wetterau, while in the Palatinate they retained few
places besides Frankenthal. Landau and Kronweisenberg openly declared
for the Swedes; Spires offered troops for the king's service; Manheim
was gained through the prudence of the Duke Bernard of Weimar, and the
negligence of its governor, who, for thi
