It was but a brief respite. At nightfall there was a lull in the tempest, and the garrison crept again to the ramparts. Instantly the departing roar of the winds and waters were succeeded by fainter but still more threatening sounds, and the sentinels and the drums and trumpets to rally the garrison, when the attack came. The sleepless Spaniards were already upon them. In the Porcupine fort, a blaze of wickerwork and building materials suddenly illuminated the gathering gloom of night; and the loud cries of the assailants, who had succeeded in kindling this fire by their missiles, proclaimed the fierceness of the attack. Governor Dorp was himself in the fort, straining every nerve to extinguish the flames, and to hold this most important position. He was successful. After a brief but bloody encounter the Spaniards were repulsed with heavy loss. All was quiet again, and the garrison in the Porcupine were congratulating themselves on their victory when suddenly the ubiquitous Philip Fleeting plunged, with a face of horror, into the governor's quarters, informing him that the attack on the redoubt had been a feint, and that the Spaniards were at that very moment swarming all over the three external forts, called the South Square, the West Square, and the Polder. These points, which have been already described, were most essential to the protection of the place, as without them the whole counterscarp was in danger. It was to save those exposed but vital positions that Sir Francis Vere had resorted to the slippery device of the last Christmas Eve but one.
