Their course, however, was irregular, and destitute of steersmen they arrived singly and separately at the floating works, where they continued hanging or were dashed off sidewise on the shore. The foremost powder-ships, which were intended to set fire to the floating works, were cast, by the force of a squall which arose at that instant, on the Flemish coast. One of the two, the "Fortune," grounded in its passage before it reached the bridge, and killed by its explosion some Spanish soldiers who were at work in a neighboring battery. The other and larger fire-ship, called the "Hope," narrowly escaped a similar fate. The current drove her against the floating defences towards the Flemish bank, where it remained hanging, and had it taken fire at that moment the greatest part of its effect would have been lost. Deceived by the flames which this machine, like the other vessels, emitted, the Spaniards took it for a common fire-ship, intended to burn the bridge of boats. And as they had seen them extinguished one after the other without further effect all fears were dispelled, and the Spaniards began to ridicule the preparations of the enemy, which had been ushered in with so much display and now had so absurd an end. Some of the boldest threw themselves into the stream in order to get a close view of the fire-ship and extinguish it, when by its weight it suddenly broke through, burst the floating work which had detained it, and drove with terrible force on the bridge of boats. All was now in commotion on the bridge, and the prince called to the sailors to keep the vessel off with poles, and to extinguish the flames before they caught the timbers.
