Early on the morning of the 16th of May the enemy's forces were in motion. With the dusk of dawn there came floating down from Lillo, over the inundated country, four burning vessels, which so alarmed the guards upon the dams, who recollected the former terrible explosion, that they hastily retreated to the next battery. This was exactly what the enemy desired. In these vessels, which had merely the appearance of fire- ships, soldiers were concealed, who now suddenly jumped ashore, and succeeded in mounting the dam at the undefended spot, between the St. George and Pile batteries. Immediately afterward the whole Zealand fleet showed itself, consisting of numerous ships-of-war, transports, and a crowd of smaller craft, which were laden with great sacks of earth, wool, fascines, gabions, and the like, for throwing up breastworks wherever necessary, The ships-of-war were furnished with powerful artillery, and numerously and bravely manned, and a whole army of pioneers accompanied it in order to dig through the dam as soon as it should be in their possession. The Zealanders had scarcely begun on their side to ascend the dam when the fleet of Antwerp advanced from Osterweel and attacked it on the other. A high breastwork was hastily thrown up between the two nearest hostile batteries, so as at once to divide the two garrisons and to cover the pioneers. The latter, several hundreds in number, now fell to work with their spades on both sides of the dam, and dug with such energy that hopes were entertained of soon seeing the two seas united. But meanwhile the Spaniards also had gained time to hasten to the spot from the two nearest redoubts, and make a spirited assault, while the guns from the battery of St. George played incessantly on the enemy's fleet. A furious battle now raged in the quarter where they were cutting through the dike and throwing up the breastworks. The Zealanders had drawn a strong line of troops round the pioneers to keep the enemy from interrupting their work, and in this confusion of battle, in the midst of a storm of bullets from the enemy, often up to the breast in water, among the dead and dying, the pioneers pursued their work, under the incessant exhortations of the merchants, who impatiently waited to see the dam opened and their vessels in safety. The importance of the result, which it might be said depended entirely upon their spades, appeared to animate even the common laborers with heroic courage. Solely intent upon their task, they neither saw nor heard the work of death which was going on around them, and as fast as the foremost ranks fell those behind them pressed into their places. Their operations were greatly impeded by the piles which had been driven in, but still more by the attacks of the Spaniards, who burst with desperate courage through the thickest of the enemy, stabbed the pioneers in the pits where they were digging, and filled up again with dead bodies the
