than four thousand men. In the beginning it was much less numerous.
The same circumstances, however, which assisted the initiatory operations
of Don Frederic, were of advantage to the Harlemers. A dense frozen fog
hung continually over the surface of the lake. Covered by this curtain,
large supplies of men, provisions, and ammunition were daily introduced
into the city, notwithstanding all the efforts of the besieging force.
Sledges skimming over the ice, men, women, and even children, moving on
their skates as swiftly as the wind, all brought their contributions in
the course of the short dark days and long nights of December, in which
the wintry siege was opened.

The garrison at last numbered about one thousand pioneers or delvers,
three thousand fighting men, and about three hundred fighting women. The
last was a most efficient corps, all females of respectable character,
armed with sword, musket, and dagger. Their chief, Kenau Hasselaer, was a
widow of distinguished family and unblemished reputation, about
forty-seven years of age, who, at the head of her amazons, participated
in many of the most fiercely contested actions of the siege, both within
and without the walls. When such a spirit animated the maids and matrons
of the city, it might be expected that the men would hardly surrender the
place without a struggle. The Prince had assembled a force of three or
four thousand men at Leyden, which he sent before the middle of December
towards the city under the command of De la Marck. These troops were,
however, attacked on the way by a strong detachment under Bossu,
Noircarmes, and Romero. After a sharp, action in a heavy snow-storm, De
la Marek was completely routed. One thousand of his soldiers were cut to
pieces, and a large number carried off as prisoners to the gibbets, which
were already conspicuously erected in the Spanish camp, and which from
the commencement to the close of the siege were never bare of victims.
Among the captives was a gallant officer, Baptist van Trier, for whom De
la Marck in vain offered two thousand crowns and nineteen Spanish
prisoners. The proposition was refused with contempt. Van Trier was
hanged upon the gallows by one leg until he was dead, in return for which
barbarity the nineteen Spaniards were immediately gibbeted by De la
Marck. With this interchange of cruelties the siege may be said to have
opened.

Don Frederic had stationed himself in a position opposite to the gate of
