three regiments which he threw into garrison, and thus set free an equal
number of fresh troops, which were forthwith sent to the camp of Maurice.
The prince at the same time was made aware that Verdugo was about to
receive important succour, and he was advised by the deputies of the
States-General present at his headquarters to send out his German Reiters
to intercept them. Maurice refused. Should his cavalry be defeated, he
said, his whole army would be endangered. He determined to await within
his fortified camp the attack of the relieving force.

During the whole month of August he proceeded steadily with his sapping

weather had impeded his operations and the march of the relieving army.
Nevertheless that army was at last approaching. The regiments of
Mondragon, Charles Mansfeld, Gonzaga, Berlaymont, and Arenberg had been
despatched to reinforce Verdugo. On the 23rd August, having crossed the
Rhine at Rheinberg, they reached Olfen in the country of Benthem, ten
miles from Coeworden. Here they threw up rockets and made other signals
that relief was approaching the town. On the 3rd of September Verdugo,
with the whole force at his disposal, amounting to four thousand foot and
eighteen hundred horse, was at the village of Emblichen, within a league
of the besieged city. That night a peasant was captured with letters
from Verdugo to the Governor of Coeworden, giving information that he
intended to make an assault on the besiegers on the night of 6th-7th
September.

Thus forewarned, Maurice took the best precautions and calmly within his
entrenchments awaited the onslaught. Punctual to his appointment,
