Their approach was entirely unobserved, and they effected an entrance into the town.
Scarcely had they done so when they came upon a body of three hundred Imperialists who were about to make a sally under Colonel Gratz, son of the governor.

The pikemen at once fell upon them.

Taken by surprise the Imperialists fought nevertheless stoutly, and eighty of the Scots fell under the fire of their musketry.

But the pikemen charged home; Colonel Gratz was killed, with many of his men, and the rest taken prisoners.
Hepburn marching on behind heard the din of musketry and pressed forward; before reaching the town he found a place in the swamp sufficiently firm to enable his men to march across it, and, turning off, he led his troops between the town and the redoubt, and then attacked the latter in the rear where its defences were weak, and after three minutes' fighting with its surprised and disheartened garrison the latter surrendered.
The redoubt having fallen, and Munro's men having effected a lodgment in the town, while the retreat on one side was cut off by the force of Gustavus, and on the other by a strong body of cavalry under Marshal Horn, the governor sent a drummer to Colonel Munro to say that he was ready to surrender, and to ask for terms.

The drummer was sent to Gustavus, who agreed that the garrison should be allowed to march away with the honours of war, taking their baggage and effects with them.
Accordingly at eight o'clock the Count of Gratz at the head of his soldiers marched out with colours flying and drums beating, and retired into Silesia.
