een constructing a half moon of solid masonry on the inside of
the same portal. Old men, feeble women, tender children, united with the
able-bodied to accomplish this work, by which they hoped still to
maintain themselves after the ravelin had fallen:

On the 31st of January, after two or three days' cannonade against the
gates of the Cross and of Saint John, and the intervening curtains, Don
Frederic ordered a midnight assault. The walls had been much shattered,
part of the John's-gate was in ruins; the Spaniards mounted the breach in
great numbers; the city was almost taken by surprise; while the
Commander-in-chief, sure of victory, ordered the whole of his forces
under arms to cut off the population who were to stream panic-struck from
every issue. The attack was unexpected, but the forty or fifty sentinels
defended the walls while they sounded the alarm. The tocsin bells tolled,
and the citizens, whose sleep was not-apt to be heavy during that
perilous winter, soon manned the ramparts again. The daylight came upon
them while the fierce struggle was still at its height. The besieged, as

on the inner side. The reason why the ravelin had been at last conceded
was revealed. The half moon, whose existence they had not suspected, rose
before them bristling with cannon. A sharp fire was instantly opened upon
the besiegers, while at the same instant the ravelin, which the citizens
had undermined, blew up with a severe explosion, carrying into the air
all the soldiers who had just entered it so triumphantly. This was the
turning point. The retreat was sounded, and the Spaniards fled to their
camp, leaving at least three hundred dead beneath the walls. Thus was a
second assault, made by an overwhelming force and led by the most
accomplished generals of Spain, signally and gloriously repelled by the
plain burghers of Harlem.

It became now almost evident that t
