The Prince of Espinoy was absent with the army in the north, but the Princess commanded in his absence.
She fulfilled her duty in a manner worthy of the house from which she sprang, for the blood of Count Horn was in her veins.

The daughter of Mary, de Montmorency, the admiral's sister, answered the summons of Parma to surrender at discretion with defiance.

The garrison was encouraged by her steadfastness.

The Princess appeared daily among her troops, superintending the defences, and personally directing the officers.
During one of the assaults, she is said, but perhaps erroneously; to have been wounded in the arm, notwithstanding which she refused to retire.
The siege lasted two months.

Meantime, it became impossible for Orange and the estates, notwithstanding their efforts, to raise a sufficient force to drive Parma from his entrenchments.
