As they approached the forts--Grimeston in front closely guarded by the Spanish captain--it was seen by the assailants that Redhead had kept his word: the drawbridge across the moat was down and the portcullis was up. Within the fort Lord Willoughby, Vere, and two thousand men were waiting them. When about fifty had crossed the drawbridge the portcullis was suddenly let fall and the drawbridge hauled up. As the portcullis thundered down Grimeston tripped up the surprised Spaniard, and, leaping into the water, managed to make his way to the foot of the walls. A discharge of musketry and artillery from the fort killed a hundred and fifty of the attacking party, while those who had crossed the drawbridge were all either killed or taken prisoners. But the water in the moat was low. The Spaniards gallantly waded across and attacked the palisades, but were repulsed in their endeavour to climb them. While the fight was going on the water in the moat was rising, and scores were washed away and drowned as they attempted to return. Parma continued the siege for some little time, but made no real attempt to take the place after having been repulsed at the north fort; and on the 12th of November broke up his camp and returned to Brussels. After the siege was over Lord Willoughby knighted twelve of his principal officers, foremost among whom was Francis Vere, who was now sent home with despatches by his general, and remained in England until the end of January, when he was appointed sergeant-major-general of the forces, a post of great responsibility and much honour, by Lord Willoughby, with the full approval of the queen's government. He was accompanied on his return by his brother Robert. A month after Sir Francis Vere's return Lord Willoughby left for England, and the whole burden of operations in the field fell upon Vere. His first trouble arose from the mutinous conduct of the garrison of Gertruydenberg. This was an important town on the banks of the old Maas, and was strongly fortified, one side being protected by the Maas while the river Douge swept round two other sides of its walls. Its governor, Count Hohenlohe, had been unpopular, the troops had received no pay, and there had been a partial mutiny before the siege of Bergen-op-Zoom began. This was appeased by the appointment of Sir John Wingfield, Lord Willoughby's brother-in-law, as its governor.
