From hence the army marched to Mentz, which in four days’ time capitulated, with the fort and citadel, and the city paid his Majesty 300,000 dollars to be exempted from the fury of the soldiers. Here the king himself drew the plan of those invincible fortifications which to this day makes it one of the strongest cities in Germany.
Friburg, Koningstien, Neustadt, Kaiserslautern, and almost all the Lower Palatinate, surrendered at the very terror of the King of Sweden’s approach, and never suffered the danger of a siege.
The king held a most magnificent court at Mentz, attended by the Landgrave of Hesse, with an incredible number of princes and lords of the empire, with ambassadors and residents of foreign princes; and here his Majesty stayed till March, when the queen, with a great retinue of Swedish nobility, came from Erfurt to see him. The king, attended by a gallant train of German nobility, went to Frankfort, and from thence on to Hoest, to meet the queen, where her Majesty arrived February 8.
During the king’s stay in these parts, his armies were not idle, his troops, on one side under the Rhinegrave, a brave and ever-fortunate commander, and under the Landgrave of Hesse, on the other, ranged the country from Lorraine to Luxemburg, and past the Moselle on the west, and the Weser on the north. Nothing could stand before them: the Spanish army which came to the relief of the Catholic Electors was everywhere defeated and beaten quite out of the country, and the Lorraine army quite ruined. ’Twas a most pleasant court sure as ever was seen, where every day expresses arrived of armies defeated, towns surrendered, contributions agreed upon, parties routed, prisoners taken, and princes sending ambassadors to sue for truces and neutralities, to make submissions and compositions, and to pay arrears and contributions.
