It was at once obvious that the watery expanse between Harlem and
Amsterdam would be the principal theatre of the operations about to
commence. The siege was soon begun. The fugitive burgomaster, De Fries,
had tho effrontery, with the advice of Alva, to address a letter to the
citizens, urging them to surrender at discretion. The messenger was
hanged--a cruel but practical answer, which put an end to all further
traitorous communications. This was in the first week of December. On
the 10th, Don Frederic, sent a strong detachment to capture the fort and
village of Sparendam, as an indispensable preliminary to the commencement
of the siege. A peasant having shown Zapata, the commander of the
expedition, a secret passage across the flooded and frozen meadows, the
Spaniards stormed the place gallantly, routed the whole garrison, killed
three hundred, and took possession of the works and village. Next day,
Don Frederic appeared before the walls of Harlem, and proceeded regularly
to invest the place. The misty weather favored his operations, nor did
he cease reinforcing himself; until at least thirty thousand men,
including fifteen hundred cavalry, had been encamped around the city.
The Germans, under Count Overstein, were stationed in a beautiful and
extensive grove of limes and beeches, which spread between the southern
walls and the shore of Harlem Lake. Don Frederic, with his Spaniards,
took up a position on the opposite side, at a place called the House of
Kleef, the ruins of which still remain. The Walloons, and other
regiments were distributed in different places, so as completely to
encircle the town.
