The bombardment of St. Nicholas continued for some days. A breach was fast forming in the wall, and a slope composed of the fallen rubbish extended from the front of the breach to the water's edge. The grand master was frequently on the spot, and as this was at present the sole object of attack, the garrison was strengthened by as many knights as could be sheltered within its walls. At night the shattered masonry that had fallen inside was carried out, and with it a new work thrown up across the mole, to strengthen the defence on that side, should the enemy land between the town and the fort. Small batteries were planted wherever they could sweep the approaches to the breach, and planks studded with nails were sunk in the shallow water of the harbour, to impede the progress of those who might attempt to swim or wade across. For the time, therefore, the functions of Gervaise were in abeyance, and he laboured with the rest of the garrison at the defences.
